Users who wish +to use, test, and provide feedback on the new features are encouraged to try +this branch. However, this branch provides no stability guarantees and reserves +the right to change and break the API at any time. + +## Further knowledge + +It may help to read the [Google Test documentation](https://github.com/google/googletest/blob/master/googletest/docs/primer.md) +as some of the structural aspects of the APIs are similar. + +## Example usage +### Basic usage +Define a function that executes the code to be measured, register it as a +benchmark function using the `BENCHMARK` macro, and ensure an appropriate `main` +function is available: + +```c++ +#include + +static void BM_StringCreation(benchmark::State& state) { + for (auto _ : state) + std::string empty_string; +} +// Register the function as a benchmark +BENCHMARK(BM_StringCreation); + +// Define another benchmark +static void BM_StringCopy(benchmark::State& state) { + std::string x = "hello"; + for (auto _ : state) + std::string copy(x); +} +BENCHMARK(BM_StringCopy); + +BENCHMARK_MAIN(); +``` + +Don't forget to inform your linker to add benchmark library e.g. through +`-lbenchmark` compilation flag. Alternatively, you may leave out the +`BENCHMARK_MAIN();` at the end of the source file and link against +`-lbenchmark_main` to get the same default behavior. + +The benchmark library will measure and report the timing for code within the +`for(...)` loop. + +#### Platform-specific libraries +When the library is built using GCC it is necessary to link with the pthread +library due to how GCC implements `std::thread`. Failing to link to pthread will +lead to runtime exceptions (unless you're using libc++), not linker errors. See +[issue #67](https://github.com/google/benchmark/issues/67) for more details. You +can link to pthread by adding `-pthread` to your linker command. Note, you can +also use `-lpthread`, but there are potential issues with ordering of command +line parameters if you use that. + +If you're running benchmarks on Windows, the shlwapi library (`-lshlwapi`) is +also required. + +If you're running benchmarks on solaris, you'll want the kstat library linked in +too (`-lkstat`). + +### Passing arguments +Sometimes a family of benchmarks can be implemented with just one routine that +takes an extra argument to specify which one of the family of benchmarks to +run. For example, the following code defines a family of benchmarks for +measuring the speed of `memcpy()` calls of different lengths: + +```c++ +static void BM_memcpy(benchmark::State& state) { + char* src = new char[state.range(0)]; + char* dst = new char[state.range(0)]; + memset(src, 'x', state.range(0)); + for (auto _ : state) + memcpy(dst, src, state.range(0)); + state.SetBytesProcessed(int64_t(state.iterations()) * + int64_t(state.range(0))); + delete[] src; + delete[] dst; +} +BENCHMARK(BM_memcpy)->Arg(8)->Arg(64)->Arg(512)->Arg(1<<10)->Arg(8<<10); +``` + +The preceding code is quite repetitive, and can be replaced with the following +short-hand. The following invocation will pick a few appropriate arguments in +the specified range and will generate a benchmark for each such argument. + +```c++ +BENCHMARK(BM_memcpy)->Range(8, 8<<10); +``` + +By default the arguments in the range are generated in multiples of eight and +the command above selects [ 8, 64, 512, 4k, 8k ]. In the following code the +range multiplier is changed to multiples of two. + +```c++ +BENCHMARK(BM_memcpy)->RangeMultiplier(2)->Range(8, 8<<10); +``` +Now arguments generated are [ 8, 16, 32, 64, 128, 256, 512, 1024, 2k, 4k, 8k ]. + +You might have a benchmark that depends on two or more inputs. For example, the +following code defines a family of benchmarks for measuring the speed of set +insertion. + +```c++ +static void BM_SetInsert(benchmark::State& state) { + std::set data; + for (auto _ : state) { + state.PauseTiming(); + data = ConstructRandomSet(state.range(0)); + state.ResumeTiming(); + for (int j = 0; j < state.range(1); ++j) + data.insert(RandomNumber()); + } +} +BENCHMARK(BM_SetInsert) + ->Args({1<<10, 128}) + ->Args({2<<10, 128}) + ->Args({4<<10, 128}) + ->Args({8<<10, 128}) + ->Args({1<<10, 512}) + ->Args({2<<10, 512}) + ->Args({4<<10, 512}) + ->Args({8<<10, 512}); +``` + +The preceding code is quite repetitive, and can be replaced with the following +short-hand. The following macro will pick a few appropriate arguments in the +product of the two specified ranges and will generate a benchmark for each such +pair. + +```c++ +BENCHMARK(BM_SetInsert)->Ranges({{1<<10, 8<<10}, {128, 512}}); +``` + +For more complex patterns of inputs, passing a custom function to `Apply` allows +programmatic specification of an arbitrary set of arguments on which to run the +benchmark. The following example enumerates a dense range on one parameter, +and a sparse range on the second. + +```c++ +static void CustomArguments(benchmark::internal::Benchmark* b) { + for (int i = 0; i <= 10; ++i) + for (int j = 32; j <= 1024*1024; j *= 8) + b->Args({i, j}); +} +BENCHMARK(BM_SetInsert)->Apply(CustomArguments); +``` + +### Calculate asymptotic complexity (Big O) +Asymptotic complexity might be calculated for a family of benchmarks. The +following code will calculate the coefficient for the high-order term in the +running time and the normalized root-mean square error of string comparison. + +```c++ +static void BM_StringCompare(benchmark::State& state) { + std::string s1(state.range(0), '-'); + std::string s2(state.range(0), '-'); + for (auto _ : state) { + benchmark::DoNotOptimize(s1.compare(s2)); + } + state.SetComplexityN(state.range(0)); +} +BENCHMARK(BM_StringCompare) + ->RangeMultiplier(2)->Range(1<<10, 1<<18)->Complexity(benchmark::oN); +``` + +As shown in the following invocation, asymptotic complexity might also be +calculated automatically. + +```c++ +BENCHMARK(BM_StringCompare) + ->RangeMultiplier(2)->Range(1<<10, 1<<18)->Complexity(); +``` + +The following code will specify asymptotic complexity with a lambda function, +that might be used to customize high-order term calculation. + +```c++ +BENCHMARK(BM_StringCompare)->RangeMultiplier(2) + ->Range(1<<10, 1<<18)->Complexity([](int n)->double{return n; }); +``` + +### Templated benchmarks +Templated benchmarks work the same way: This example produces and consumes +messages of size `sizeof(v)` `range_x` times. It also outputs throughput in the +absence of multiprogramming. + +```c++ +template int BM_Sequential(benchmark::State& state) { + Q q; + typename Q::value_type v; + for (auto _ : state) { + for (int i = state.range(0); i--; ) + q.push(v); + for (int e = state.range(0); e--; ) + q.Wait(&v); + } + // actually messages, not bytes: + state.SetBytesProcessed( + static_cast(state.iterations())*state.range(0)); +} +BENCHMARK_TEMPLATE(BM_Sequential, WaitQueue)->Range(1<<0, 1<<10); +``` + +Three macros are provided for adding benchmark templates. + +```c++ +#ifdef BENCHMARK_HAS_CXX11 +#define BENCHMARK_TEMPLATE(func, ...) // Takes any number of parameters. +#else // C++ < C++11 +#define BENCHMARK_TEMPLATE(func, arg1) +#endif +#define BENCHMARK_TEMPLATE1(func, arg1) +#define BENCHMARK_TEMPLATE2(func, arg1, arg2) +``` + +### A Faster KeepRunning loop + +In C++11 mode, a ranged-based for loop should be used in preference to +the `KeepRunning` loop for running the benchmarks. For example: + +```c++ +static void BM_Fast(benchmark::State &state) { + for (auto _ : state) { + FastOperation(); + } +} +BENCHMARK(BM_Fast); +``` + +The reason the ranged-for loop is faster than using `KeepRunning`, is +because `KeepRunning` requires a memory load and store of the iteration count +ever iteration, whereas the ranged-for variant is able to keep the iteration count +in a register. + +For example, an empty inner loop of using the ranged-based for method looks like: + +```asm +# Loop Init + mov rbx, qword ptr [r14 + 104] + call benchmark::State::StartKeepRunning() + test rbx, rbx + je .LoopEnd +.LoopHeader: # =>This Inner Loop Header: Depth=1 + add rbx, -1 + jne .LoopHeader +.LoopEnd: +``` + +Compared to an empty `KeepRunning` loop, which looks like: + +```asm +.LoopHeader: # in Loop: Header=BB0_3 Depth=1 + cmp byte ptr [rbx], 1 + jne .LoopInit +.LoopBody: # =>This Inner Loop Header: Depth=1 + mov rax, qword ptr [rbx + 8] + lea rcx, [rax + 1] + mov qword ptr [rbx + 8], rcx + cmp rax, qword ptr [rbx + 104] + jb .LoopHeader + jmp .LoopEnd +.LoopInit: + mov rdi, rbx + call benchmark::State::StartKeepRunning() + jmp .LoopBody +.LoopEnd: +``` + +Unless C++03 compatibility is required, the ranged-for variant of writing +the benchmark loop should be preferred. + +## Passing arbitrary arguments to a benchmark +In C++11 it is possible to define a benchmark that takes an arbitrary number +of extra arguments. The `BENCHMARK_CAPTURE(func, test_case_name, ...args)` +macro creates a benchmark that invokes `func` with the `benchmark::State` as +the first argument followed by the specified `args...`. +The `test_case_name` is appended to the name of the benchmark and +should describe the values passed. + +```c++ +template +void BM_takes_args(benchmark::State& state, ExtraArgs&&... extra_args) { + [...] +} +// Registers a benchmark named "BM_takes_args/int_string_test" that passes +// the specified values to `extra_args`. +BENCHMARK_CAPTURE(BM_takes_args, int_string_test, 42, std::string("abc")); +``` +Note that elements of `...args` may refer to global variables. Users should +avoid modifying global state inside of a benchmark. + +## Using RegisterBenchmark(name, fn, args...) + +The `RegisterBenchmark(name, func, args...)` function provides an alternative +way to create and register benchmarks. +`RegisterBenchmark(name, func, args...)` creates, registers, and returns a +pointer to a new benchmark with the specified `name` that invokes +`func(st, args...)` where `st` is a `benchmark::State` object. + +Unlike the `BENCHMARK` registration macros, which can only be used at the global +scope, the `RegisterBenchmark` can be called anywhere. This allows for +benchmark tests to be registered programmatically. + +Additionally `RegisterBenchmark` allows any callable object to be registered +as a benchmark. Including capturing lambdas and function objects. + +For Example: +```c++ +auto BM_test = [](benchmark::State& st, auto Inputs) { /* ... */ }; + +int main(int argc, char** argv) { + for (auto& test_input : { /* ... */ }) + benchmark::RegisterBenchmark(test_input.name(), BM_test, test_input); + benchmark::Initialize(&argc, argv); + benchmark::RunSpecifiedBenchmarks(); +} +``` + +### Multithreaded benchmarks +In a multithreaded test (benchmark invoked by multiple threads simultaneously), +it is guaranteed that none of the threads will start until all have reached +the start of the benchmark loop, and all will have finished before any thread +exits the benchmark loop. (This behavior is also provided by the `KeepRunning()` +API) As such, any global setup or teardown can be wrapped in a check against the thread +index: + +```c++ +static void BM_MultiThreaded(benchmark::State& state) { + if (state.thread_index == 0) { + // Setup code here. + } + for (auto _ : state) { + // Run the test as normal. + } + if (state.thread_index == 0) { + // Teardown code here. + } +} +BENCHMARK(BM_MultiThreaded)->Threads(2); +``` + +If the benchmarked code itself uses threads and you want to compare it to +single-threaded code, you may want to use real-time ("wallclock") measurements +for latency comparisons: + +```c++ +BENCHMARK(BM_test)->Range(8, 8<<10)->UseRealTime(); +``` + +Without `UseRealTime`, CPU time is used by default. + + +## Manual timing +For benchmarking something for which neither CPU time nor real-time are +correct or accurate enough, completely manual timing is supported using +the `UseManualTime` function. + +When `UseManualTime` is used, the benchmarked code must call +`SetIterationTime` once per iteration of the benchmark loop to +report the manually measured time. + +An example use case for this is benchmarking GPU execution (e.g. OpenCL +or CUDA kernels, OpenGL or Vulkan or Direct3D draw calls), which cannot +be accurately measured using CPU time or real-time. Instead, they can be +measured accurately using a dedicated API, and these measurement results +can be reported back with `SetIterationTime`. + +```c++ +static void BM_ManualTiming(benchmark::State& state) { + int microseconds = state.range(0); + std::chrono::duration sleep_duration { + static_cast(microseconds) + }; + + for (auto _ : state) { + auto start = std::chrono::high_resolution_clock::now(); + // Simulate some useful workload with a sleep + std::this_thread::sleep_for(sleep_duration); + auto end = std::chrono::high_resolution_clock::now(); + + auto elapsed_seconds = + std::chrono::duration_cast>( + end - start); + + state.SetIterationTime(elapsed_seconds.count()); + } +} +BENCHMARK(BM_ManualTiming)->Range(1, 1<<17)->UseManualTime(); +``` + +### Preventing optimisation +To prevent a value or expression from being optimized away by the compiler +the `benchmark::DoNotOptimize(...)` and `benchmark::ClobberMemory()` +functions can be used. + +```c++ +static void BM_test(benchmark::State& state) { + for (auto _ : state) { + int x = 0; + for (int i=0; i < 64; ++i) { + benchmark::DoNotOptimize(x += i); + } + } +} +``` + +`DoNotOptimize()` forces the *result* of `` to be stored in either +memory or a register. For GNU based compilers it acts as read/write barrier +for global memory. More specifically it forces the compiler to flush pending +writes to memory and reload any other values as necessary. + +Note that `DoNotOptimize()` does not prevent optimizations on `` +in any way. `` may even be removed entirely when the result is already +known. For example: + +```c++ + /* Example 1: `` is removed entirely. */ + int foo(int x) { return x + 42; } + while (...) DoNotOptimize(foo(0)); // Optimized to DoNotOptimize(42); + + /* Example 2: Result of '' is only reused */ + int bar(int) __attribute__((const)); + while (...) DoNotOptimize(bar(0)); // Optimized to: + // int __result__ = bar(0); + // while (...) DoNotOptimize(__result__); +``` + +The second tool for preventing optimizations is `ClobberMemory()`. In essence +`ClobberMemory()` forces the compiler to perform all pending writes to global +memory. Memory managed by block scope objects must be "escaped" using +`DoNotOptimize(...)` before it can be clobbered. In the below example +`ClobberMemory()` prevents the call to `v.push_back(42)` from being optimized +away. + +```c++ +static void BM_vector_push_back(benchmark::State& state) { + for (auto _ : state) { + std::vector v; + v.reserve(1); + benchmark::DoNotOptimize(v.data()); // Allow v.data() to be clobbered. + v.push_back(42); + benchmark::ClobberMemory(); // Force 42 to be written to memory. + } +} +``` + +Note that `ClobberMemory()` is only available for GNU or MSVC based compilers. + +### Set time unit manually +If a benchmark runs a few milliseconds it may be hard to visually compare the +measured times, since the output data is given in nanoseconds per default. In +order to manually set the time unit, you can specify it manually: + +```c++ +BENCHMARK(BM_test)->Unit(benchmark::kMillisecond); +``` + +### Reporting the mean, median and standard deviation by repeated benchmarks +By default each benchmark is run once and that single result is reported. +However benchmarks are often noisy and a single result may not be representative +of the overall behavior. For this reason it's possible to repeatedly rerun the +benchmark. + +The number of runs of each benchmark is specified globally by the +`--benchmark_repetitions` flag or on a per benchmark basis by calling +`Repetitions` on the registered benchmark object. When a benchmark is run more +than once the mean, median and standard deviation of the runs will be reported. + +Additionally the `--benchmark_report_aggregates_only={true|false}`, +`--benchmark_display_aggregates_only={true|false}` flags or +`ReportAggregatesOnly(bool)`, `DisplayAggregatesOnly(bool)` functions can be +used to change how repeated tests are reported. By default the result of each +repeated run is reported. When `report aggregates only` option is `true`, +only the aggregates (i.e. mean, median and standard deviation, maybe complexity +measurements if they were requested) of the runs is reported, to both the +reporters - standard output (console), and the file. +However when only the `display aggregates only` option is `true`, +only the aggregates are displayed in the standard output, while the file +output still contains everything. +Calling `ReportAggregatesOnly(bool)` / `DisplayAggregatesOnly(bool)` on a +registered benchmark object overrides the value of the appropriate flag for that +benchmark. + +## User-defined statistics for repeated benchmarks +While having mean, median and standard deviation is nice, this may not be +enough for everyone. For example you may want to know what is the largest +observation, e.g. because you have some real-time constraints. This is easy. +The following code will specify a custom statistic to be calculated, defined +by a lambda function. + +```c++ +void BM_spin_empty(benchmark::State& state) { + for (auto _ : state) { + for (int x = 0; x < state.range(0); ++x) { + benchmark::DoNotOptimize(x); + } + } +} + +BENCHMARK(BM_spin_empty) + ->ComputeStatistics("max", [](const std::vector& v) -> double { + return *(std::max_element(std::begin(v), std::end(v))); + }) + ->Arg(512); +``` + +## Fixtures +Fixture tests are created by +first defining a type that derives from `::benchmark::Fixture` and then +creating/registering the tests using the following macros: + +* `BENCHMARK_F(ClassName, Method)` +* `BENCHMARK_DEFINE_F(ClassName, Method)` +* `BENCHMARK_REGISTER_F(ClassName, Method)` + +For Example: + +```c++ +class MyFixture : public benchmark::Fixture {}; + +BENCHMARK_F(MyFixture, FooTest)(benchmark::State& st) { + for (auto _ : st) { + ... + } +} + +BENCHMARK_DEFINE_F(MyFixture, BarTest)(benchmark::State& st) { + for (auto _ : st) { + ... + } +} +/* BarTest is NOT registered */ +BENCHMARK_REGISTER_F(MyFixture, BarTest)->Threads(2); +/* BarTest is now registered */ +``` + +### Templated fixtures +Also you can create templated fixture by using the following macros: + +* `BENCHMARK_TEMPLATE_F(ClassName, Method, ...)` +* `BENCHMARK_TEMPLATE_DEFINE_F(ClassName, Method, ...)` + +For example: +```c++ +template +class MyFixture : public benchmark::Fixture {}; + +BENCHMARK_TEMPLATE_F(MyFixture, IntTest, int)(benchmark::State& st) { + for (auto _ : st) { + ... + } +} + +BENCHMARK_TEMPLATE_DEFINE_F(MyFixture, DoubleTest, double)(benchmark::State& st) { + for (auto _ : st) { + ... + } +} + +BENCHMARK_REGISTER_F(MyFixture, DoubleTest)->Threads(2); +``` + +## User-defined counters + +You can add your own counters with user-defined names. The example below +will add columns "Foo", "Bar" and "Baz" in its output: + +```c++ +static void UserCountersExample1(benchmark::State& state) { + double numFoos = 0, numBars = 0, numBazs = 0; + for (auto _ : state) { + // ... count Foo,Bar,Baz events + } + state.counters["Foo"] = numFoos; + state.counters["Bar"] = numBars; + state.counters["Baz"] = numBazs; +} +``` + +The `state.counters` object is a `std::map` with `std::string` keys +and `Counter` values. The latter is a `double`-like class, via an implicit +conversion to `double&`. Thus you can use all of the standard arithmetic +assignment operators (`=,+=,-=,*=,/=`) to change the value of each counter. + +In multithreaded benchmarks, each counter is set on the calling thread only. +When the benchmark finishes, the counters from each thread will be summed; +the resulting sum is the value which will be shown for the benchmark. + +The `Counter` constructor accepts three parameters: the value as a `double` +; a bit flag which allows you to show counters as rates, and/or as per-thread +iteration, and/or as per-thread averages, and/or iteration invariants; +and a flag specifying the 'unit' - i.e. is 1k a 1000 (default, +`benchmark::Counter::OneK::kIs1000`), or 1024 +(`benchmark::Counter::OneK::kIs1024`)? + +```c++ + // sets a simple counter + state.counters["Foo"] = numFoos; + + // Set the counter as a rate. It will be presented divided + // by the duration of the benchmark. + state.counters["FooRate"] = Counter(numFoos, benchmark::Counter::kIsRate); + + // Set the counter as a thread-average quantity. It will + // be presented divided by the number of threads. + state.counters["FooAvg"] = Counter(numFoos, benchmark::Counter::kAvgThreads); + + // There's also a combined flag: + state.counters["FooAvgRate"] = Counter(numFoos,benchmark::Counter::kAvgThreadsRate); + + // This says that we process with the rate of state.range(0) bytes every iteration: + state.counters["BytesProcessed"] = Counter(state.range(0), benchmark::Counter::kIsIterationInvariantRate, benchmark::Counter::OneK::kIs1024); +``` + +When you're compiling in C++11 mode or later you can use `insert()` with +`std::initializer_list`: + +```c++ + // With C++11, this can be done: + state.counters.insert({{"Foo", numFoos}, {"Bar", numBars}, {"Baz", numBazs}}); + // ... instead of: + state.counters["Foo"] = numFoos; + state.counters["Bar"] = numBars; + state.counters["Baz"] = numBazs; +``` + +### Counter reporting + +When using the console reporter, by default, user counters are are printed at +the end after the table, the same way as ``bytes_processed`` and +``items_processed``. This is best for cases in which there are few counters, +or where there are only a couple of lines per benchmark. Here's an example of +the default output: + +``` +------------------------------------------------------------------------------ +Benchmark Time CPU Iterations UserCounters... +------------------------------------------------------------------------------ +BM_UserCounter/threads:8 2248 ns 10277 ns 68808 Bar=16 Bat=40 Baz=24 Foo=8 +BM_UserCounter/threads:1 9797 ns 9788 ns 71523 Bar=2 Bat=5 Baz=3 Foo=1024m +BM_UserCounter/threads:2 4924 ns 9842 ns 71036 Bar=4 Bat=10 Baz=6 Foo=2 +BM_UserCounter/threads:4 2589 ns 10284 ns 68012 Bar=8 Bat=20 Baz=12 Foo=4 +BM_UserCounter/threads:8 2212 ns 10287 ns 68040 Bar=16 Bat=40 Baz=24 Foo=8 +BM_UserCounter/threads:16 1782 ns 10278 ns 68144 Bar=32 Bat=80 Baz=48 Foo=16 +BM_UserCounter/threads:32 1291 ns 10296 ns 68256 Bar=64 Bat=160 Baz=96 Foo=32 +BM_UserCounter/threads:4 2615 ns 10307 ns 68040 Bar=8 Bat=20 Baz=12 Foo=4 +BM_Factorial 26 ns 26 ns 26608979 40320 +BM_Factorial/real_time 26 ns 26 ns 26587936 40320 +BM_CalculatePiRange/1 16 ns 16 ns 45704255 0 +BM_CalculatePiRange/8 73 ns 73 ns 9520927 3.28374 +BM_CalculatePiRange/64 609 ns 609 ns 1140647 3.15746 +BM_CalculatePiRange/512 4900 ns 4901 ns 142696 3.14355 +``` + +If this doesn't suit you, you can print each counter as a table column by +passing the flag `--benchmark_counters_tabular=true` to the benchmark +application. This is best for cases in which there are a lot of counters, or +a lot of lines per individual benchmark.

This is because ``BM_Factorial`` does +not have the same counter set as ``BM_UserCounter``. + +## Exiting Benchmarks in Error + +When errors caused by external influences, such as file I/O and network +communication, occur within a benchmark the +`State::SkipWithError(const char* msg)` function can be used to skip that run +of benchmark and report the error. Note that only future iterations of the +`KeepRunning()` are skipped. For the ranged-for version of the benchmark loop +Users must explicitly exit the loop, otherwise all iterations will be performed. +Users may explicitly return to exit the benchmark immediately. + +The `SkipWithError(...)` function may be used at any point within the benchmark, +including before and after the benchmark loop. + +For example: + +```c++ +static void BM_test(benchmark::State& state) { + auto resource = GetResource(); + if (!resource.good()) { + state.SkipWithError("Resource is not good!"); + // KeepRunning() loop will not be entered. + } + for (state.KeepRunning()) { + auto data = resource.read_data(); + if (!resource.good()) { + state.SkipWithError("Failed to read data!"); + break; // Needed to skip the rest of the iteration. + } + do_stuff(data); + } +} + +static void BM_test_ranged_fo(benchmark::State & state) { + state.SkipWithError("test will not be entered"); + for (auto _ : state) { + state.SkipWithError("Failed!"); + break; // REQUIRED to prevent all further iterations. + } +} +``` + +## Running a subset of the benchmarks + +The `--benchmark_filter=` option can be used to only run the benchmarks +which match the specified ``.

As such, faster benchmark +functions will be run for more iterations than slower benchmark functions, and +the number of iterations is thus reported. + +In all cases, the number of iterations for which the benchmark is run is +governed by the amount of time the benchmark takes. Concretely, the number of +iterations is at least one, not more than 1e9, until CPU time is greater than +the minimum time, or the wallclock time is 5x minimum time. The minimum time is +set per benchmark by calling `MinTime` on the registered benchmark object. + +Average timings are then reported over the iterations run. If multiple +repetitions are requested using the `--benchmark_repetitions` command-line +option, or at registration time, the benchmark function will be run several +times and statistical results across these repetitions will also be reported. + +As well as the per-benchmark entries, a preamble in the report will include +information about the machine on which the benchmarks are run. + +### Output Formats +The library supports multiple output formats. Use the +`--benchmark_format=` flag to set the format type. `console` +is the default format. + +The Console format is intended to be a human readable format. By default +the format generates color output. Context is output on stderr and the +tabular data on stdout. Example tabular output looks like: +``` +Benchmark Time(ns) CPU(ns) Iterations +---------------------------------------------------------------------- +BM_SetInsert/1024/1 28928 29349 23853 133.097kB/s 33.2742k items/s +BM_SetInsert/1024/8 32065 32913 21375 949.487kB/s 237.372k items/s +BM_SetInsert/1024/10 33157 33648 21431 1.13369MB/s 290.225k items/s +``` + +The JSON format outputs human readable json split into two top level attributes. +The `context` attribute contains information about the run in general, including +information about the CPU and the date. +The `benchmarks` attribute contains a list of every benchmark run. Example json +output looks like: +```json +{ + "context": { + "date": "2015/03/17-18:40:25", + "num_cpus": 40, + "mhz_per_cpu": 2801, + "cpu_scaling_enabled": false, + "build_type": "debug" + }, + "benchmarks": [ + { + "name": "BM_SetInsert/1024/1", + "iterations": 94877, + "real_time": 29275, + "cpu_time": 29836, + "bytes_per_second": 134066, + "items_per_second": 33516 + }, + { + "name": "BM_SetInsert/1024/8", + "iterations": 21609, + "real_time": 32317, + "cpu_time": 32429, + "bytes_per_second": 986770, + "items_per_second": 246693 + }, + { + "name": "BM_SetInsert/1024/10", + "iterations": 21393, + "real_time": 32724, + "cpu_time": 33355, + "bytes_per_second": 1199226, + "items_per_second": 299807 + } + ] +} +``` + +The CSV format outputs comma-separated values. The `context` is output on stderr +and the CSV itself on stdout. Example CSV output looks like: +``` +name,iterations,real_time,cpu_time,bytes_per_second,items_per_second,label +"BM_SetInsert/1024/1",65465,17890.7,8407.45,475768,118942, +"BM_SetInsert/1024/8",116606,18810.1,9766.64,3.27646e+06,819115, +"BM_SetInsert/1024/10",106365,17238.4,8421.53,4.74973e+06,1.18743e+06, +``` + +### Output Files +The library supports writing the output of the benchmark to a file specified +by `--benchmark_out=`. The format of the output can be specified +using `--benchmark_out_format={json|console|csv}`. Specifying +`--benchmark_out` does not suppress the console output. + +## Result comparison + +It is possible to compare the benchmarking results. See [Additional Tooling Documentation](docs/tools.md) + +## Debug vs Release +By default, benchmark builds as a debug library. You will see a warning in the +output when this is the case.

Please see the documentation +linked above for information on how to write `CHECK` directives. + +#### Tips and Tricks: + +* Tests should match the minimal amount of output required to establish +correctness. `CHECK` directives don't have to match on the exact next line +after the previous match, so tests should omit checks for unimportant +bits of assembly. ([`CHECK-NEXT`](https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-next-directive) +can be used to ensure a match occurs exactly after the previous match). + +* The tests are compiled with `-O3 -g0`. So we're only testing the +optimized output. + +* The assembly output is further cleaned up using `tools/strip_asm.py`. +This removes comments, assembler directives, and unused labels before +the test is run. + +* The generated and stripped assembly file for a test is output under +`/test/.s` + +* Filecheck supports using [`CHECK` prefixes](https://llvm.org/docs/CommandGuide/FileCheck.html#cmdoption-check-prefixes) +to specify lines that should only match in certain situations. +The Benchmark tests use `CHECK-CLANG` and `CHECK-GNU` for lines that +are only expected to match Clang or GCC's output respectively. Normal +`CHECK` lines match against all compilers. (Note: `CHECK-NOT` and +`CHECK-LABEL` are NOT prefixes. They are versions of non-prefixed +`CHECK` lines) + +* Use `extern "C"` to disable name mangling for specific functions. This +makes them easier to name in the `CHECK` lines. + + +## Problems Writing Portable Tests + +Writing tests which check the code generated by a compiler are +inherently non-portable. Different compilers and even different compiler +versions may generate entirely different code. The Benchmark tests +must tolerate this. + +LLVM Filecheck provides a number of mechanisms to help write +"more portable" tests; including [matching using regular expressions](https://llvm.org/docs/CommandGuide/FileCheck.html#filecheck-pattern-matching-syntax), +allowing the creation of [named variables](https://llvm.org/docs/CommandGuide/FileCheck.html#filecheck-variables) +for later matching, and [checking non-sequential matches](https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-dag-directive). + +#### Capturing Variables + +For example, say GCC stores a variable in a register but Clang stores +it in memory. To write a test that tolerates both cases we "capture" +the destination of the store, and then use the captured expression +to write the remainder of the test. + +```c++ +// CHECK-LABEL: test_div_no_op_into_shr: +extern "C" void test_div_no_op_into_shr(int value) { + int divisor = 2; + benchmark::DoNotOptimize(divisor); // hide the value from the optimizer + return value / divisor; + + // CHECK: movl $2, [[DEST:.*]] + // CHECK: idivl [[DEST]] + // CHECK: ret +} +``` + +#### Using Regular Expressions to Match Differing Output + +Often tests require testing assembly lines which may subtly differ +between compilers or compiler versions. A common example of this +is matching stack frame addresses. In this case regular expressions +can be used to match the differing bits of output. For example: + +```c++ +int ExternInt; +struct Point { int x, y, z; }; + +// CHECK-LABEL: test_store_point: +extern "C" void test_store_point() { + Point p{ExternInt, ExternInt, ExternInt}; + benchmark::DoNotOptimize(p); + + // CHECK: movl ExternInt(%rip), %eax + // CHECK: movl %eax, -{{[0-9]+}}(%rsp) + // CHECK: movl %eax, -{{[0-9]+}}(%rsp) + // CHECK: movl %eax, -{{[0-9]+}}(%rsp) + // CHECK: ret +} +``` + +## Current Requirements and Limitations + +The tests require Filecheck to be installed along the `PATH` of the +build machine. Otherwise the tests will be disabled. + +Additionally, as mentioned in the previous section, codegen tests are +inherently non-portable. Currently the tests are limited to: + +* x86_64 targets. +* Compiled with GCC or Clang + +Further work could be done, at least on a limited basis, to extend the +tests to other architectures and compilers (using `CHECK` prefixes). + +Furthermore, the tests fail for builds which specify additional flags +that modify code generation, including `--coverage` or `-fsanitize=`. + diff --git a/packages/google-crc32c/crc32c/third_party/benchmark/docs/tools.md b/packages/google-crc32c/crc32c/third_party/benchmark/docs/tools.md new file mode 100644 index 000000000000..4a3b2e9bd2c9 --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/benchmark/docs/tools.md @@ -0,0 +1,199 @@ +# Benchmark Tools + +## compare.py + +The `compare.py` can be used to compare the result of benchmarks. + +**NOTE**: the utility relies on the scipy package which can be installed using [these instructions](https://www.scipy.org/install.html). + +### Displaying aggregates only + +The switch `-a` / `--display_aggregates_only` can be used to control the +displayment of the normal iterations vs the aggregates.

(In particular, if you are using +InstallFailureSignalHandler(), the signal may be raised in the middle +of malloc, holding some malloc-related locks when they invoke the +stack unwinder. The built-in stack unwinder may call malloc +recursively, which may require the thread to acquire a lock it already +holds: deadlock.) + +For that reason, if you use a 64-bit system and you need +InstallFailureSignalHandler(), we strongly recommend you install +libunwind before trying to configure or install google glog. +libunwind can be found at + + http://download.savannah.nongnu.org/releases/libunwind/libunwind-snap-070410.tar.gz + +Even if you already have libunwind installed, you will probably still +need to install from the snapshot to get the latest version. + +CAUTION: if you install libunwind from the URL above, be aware that +you may have trouble if you try to statically link your binary with +glog: that is, if you link with 'gcc -static -lgcc_eh ...'. This +is because both libunwind and libgcc implement the same C++ exception +handling APIs, but they implement them differently on some platforms. +This is not likely to be a problem on ia64, but may be on x86-64. + +Also, if you link binaries statically, make sure that you add +-Wl,--eh-frame-hdr to your linker options. This is required so that +libunwind can find the information generated by the compiler required +for stack unwinding. + +Using -static is rare, though, so unless you know this will affect you +it probably won't. + +If you cannot or do not wish to install libunwind, you can still try +to use two kinds of stack-unwinder: 1. glibc built-in stack-unwinder +and 2. frame pointer based stack-unwinder. + +1. As we already mentioned, glibc's unwinder has a deadlock issue. +However, if you don't use InstallFailureSignalHandler() or you don't +worry about the rare possibilities of deadlocks, you can use this +stack-unwinder. If you specify no options and libunwind isn't +detected on your system, the configure script chooses this unwinder by +default. + +2. The frame pointer based stack unwinder requires that your +application, the glog library, and system libraries like libc, all be +compiled with a frame pointer. This is *not* the default for x86-64. + +If you are on x86-64 system, know that you have a set of system +libraries with frame-pointers enabled, and compile all your +applications with -fno-omit-frame-pointer, then you can enable the +frame pointer based stack unwinder by passing the +--enable-frame-pointers flag to configure. + + +Basic Installation +================== + +Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/packages/google-crc32c/crc32c/third_party/glog/Makefile.am b/packages/google-crc32c/crc32c/third_party/glog/Makefile.am new file mode 100644 index 000000000000..d578a4082d31 --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/glog/Makefile.am @@ -0,0 +1,260 @@ +## Process this file with automake to produce Makefile.in + +AUTOMAKE_OPTIONS=subdir-objects + +# Make sure that when we re-make ./configure, we get the macros we need +ACLOCAL_AMFLAGS = -I m4 + +# This is so we can #include +AM_CPPFLAGS = -I$(top_srcdir)/src + +# This is mostly based on configure options +AM_CXXFLAGS = + +# These are good warnings to turn on by default +if GCC + AM_CXXFLAGS += -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare +endif + +# These are x86-specific, having to do with frame-pointers +if X86_64 +if ENABLE_FRAME_POINTERS + AM_CXXFLAGS += -fno-omit-frame-pointer +else + # TODO(csilvers): check if -fomit-frame-pointer might be in $(CXXFLAGS), + # before setting this. + AM_CXXFLAGS += -DNO_FRAME_POINTER +endif +endif + +if DISABLE_RTTI + AM_CXXFLAGS += -fno-rtti +endif + +glogincludedir = $(includedir)/glog +## The .h files you want to install (that is, .h files that people +## who install this package can include in their own applications.) +## We have to include both the .h and .h.in forms.

How To Use Google Logging Library (glog)

+(as of +) + +
+ + + +

Google glog is a library that implements application-level +logging. This library provides logging APIs based on C++-style +streams and various helper macros. +You can log a message by simply streaming things to LOG(<a +particular severity level>), e.g. + +

+   #include <glog/logging.h>
+
+   int main(int argc, char* argv[]) {
+     // Initialize Google's logging library.
+     google::InitGoogleLogging(argv[0]);
+
+     // ...
+     LOG(INFO) << "Found " << num_cookies << " cookies";
+   }
+
+ +

Google glog defines a series of macros that simplify many common logging +tasks. You can log messages by severity level, control logging +behavior from the command line, log based on conditionals, abort the +program when expected conditions are not met, introduce your own +verbose logging levels, and more. This document describes the +functionality supported by glog. Please note that this document +doesn't describe all features in this library, but the most useful +ones. If you want to find less common features, please check +header files under src/glog directory. + +

Severity Level

+ +

+You can specify one of the following severity levels (in +increasing order of severity): INFO, WARNING, +ERROR, and FATAL. +Logging a FATAL message terminates the program (after the +message is logged). +Note that messages of a given severity are logged not only in the +logfile for that severity, but also in all logfiles of lower severity. +E.g., a message of severity FATAL will be logged to the +logfiles of severity FATAL, ERROR, +WARNING, and INFO. + +

+The DFATAL severity logs a FATAL error in +debug mode (i.e., there is no NDEBUG macro defined), but +avoids halting the program in production by automatically reducing the +severity to ERROR. + +

Unless otherwise specified, glog writes to the filename +"/tmp/<program name>.<hostname>.<user name>.log.<severity level>.<date>.<time>.<pid>" +(e.g., "/tmp/hello_world.example.com.hamaji.log.INFO.20080709-222411.10474"). +By default, glog copies the log messages of severity level +ERROR or FATAL to standard error (stderr) +in addition to log files. + +

Setting Flags

+ +

Several flags influence glog's output behavior. +If the Google +gflags library is installed on your machine, the +configure script (see the INSTALL file in the package for +detail of this script) will automatically detect and use it, +allowing you to pass flags on the command line. For example, if you +want to turn the flag --logtostderr on, you can start +your application with the following command line: + +

+   ./your_application --logtostderr=1
+
+ +If the Google gflags library isn't installed, you set flags via +environment variables, prefixing the flag name with "GLOG_", e.g. + +
+   GLOG_logtostderr=1 ./your_application
+
+ + + +

The following flags are most commonly used: + +

+
logtostderr (bool, default=false) +
Log messages to stderr instead of logfiles.
+Note: you can set binary flags to true by specifying +1, true, or yes (case +insensitive). +Also, you can set binary flags to false by specifying +0, false, or no (again, case +insensitive). +
stderrthreshold (int, default=2, which +is ERROR) +
Copy log messages at or above this level to stderr in +addition to logfiles. The numbers of severity levels +INFO, WARNING, ERROR, and +FATAL are 0, 1, 2, and 3, respectively. +
minloglevel (int, default=0, which +is INFO) +
Log messages at or above this level. Again, the numbers of +severity levels INFO, WARNING, +ERROR, and FATAL are 0, 1, 2, and 3, +respectively. +
log_dir (string, default="") +
If specified, logfiles are written into this directory instead +of the default logging directory. +
v (int, default=0) +
Show all VLOG(m) messages for m less or +equal the value of this flag. Overridable by --vmodule. +See the section about verbose logging for more +detail. +
vmodule (string, default="") +
Per-module verbose level. The argument has to contain a +comma-separated list of <module name>=<log level>. +<module name> +is a glob pattern (e.g., gfs* for all modules whose name +starts with "gfs"), matched against the filename base +(that is, name ignoring .cc/.h./-inl.h). +<log level> overrides any value given by --v. +See also the section about verbose logging. +
+ +

There are some other flags defined in logging.cc. Please grep the +source code for "DEFINE_" to see a complete list of all flags. + +

You can also modify flag values in your program by modifying global +variables FLAGS_* . Most settings start working +immediately after you update FLAGS_* . The exceptions are +the flags related to destination files. For example, you might want to +set FLAGS_log_dir before +calling google::InitGoogleLogging . Here is an example: + +

+   LOG(INFO) << "file";
+   // Most flags work immediately after updating values.
+   FLAGS_logtostderr = 1;
+   LOG(INFO) << "stderr";
+   FLAGS_logtostderr = 0;
+   // This won't change the log destination. If you want to set this
+   // value, you should do this before google::InitGoogleLogging .
+   FLAGS_log_dir = "/some/log/directory";
+   LOG(INFO) << "the same file";
+
+ +

Conditional / Occasional Logging

+ +

Sometimes, you may only want to log a message under certain +conditions. You can use the following macros to perform conditional +logging: + +

+   LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
+
+ +The "Got lots of cookies" message is logged only when the variable +num_cookies exceeds 10. + +If a line of code is executed many times, it may be useful to only log +a message at certain intervals. This kind of logging is most useful +for informational messages. + +
+   LOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
+
+ +

The above line outputs a log messages on the 1st, 11th, +21st, ... times it is executed. Note that the special +google::COUNTER value is used to identify which repetition is +happening. + +

You can combine conditional and occasional logging with the +following macro. + +

+   LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << google::COUNTER
+                                           << "th big cookie";
+
+ +

Instead of outputting a message every nth time, you can also limit +the output to the first n occurrences: + +

+   LOG_FIRST_N(INFO, 20) << "Got the " << google::COUNTER << "th cookie";
+
+ +

Outputs log messages for the first 20 times it is executed. Again, +the google::COUNTER identifier indicates which repetition is +happening. + +

Debug Mode Support

+ +

Special "debug mode" logging macros only have an effect in debug +mode and are compiled away to nothing for non-debug mode +compiles. Use these macros to avoid slowing down your production +application due to excessive logging. + +

+   DLOG(INFO) << "Found cookies";
+
+   DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
+
+   DLOG_EVERY_N(INFO, 10) << "Got the " << google::COUNTER << "th cookie";
+
+ +

CHECK Macros

+ +

It is a good practice to check expected conditions in your program +frequently to detect errors as early as possible. The +CHECK macro provides the ability to abort the application +when a condition is not met, similar to the assert macro +defined in the standard C library. + +

CHECK aborts the application if a condition is not +true. Unlike assert, it is *not* controlled by +NDEBUG, so the check will be executed regardless of +compilation mode. Therefore, fp->Write(x) in the +following example is always executed: + +

+   CHECK(fp->Write(x) == 4) << "Write failed!";
+
+ +

There are various helper macros for +equality/inequality checks - CHECK_EQ, +CHECK_NE, CHECK_LE, CHECK_LT, +CHECK_GE, and CHECK_GT. +They compare two values, and log a +FATAL message including the two values when the result is +not as expected. The values must have operator<<(ostream, +...) defined. + +

You may append to the error message like so: + +

+   CHECK_NE(1, 2) << ": The world must be ending!";
+
+ +

We are very careful to ensure that each argument is evaluated exactly +once, and that anything which is legal to pass as a function argument is +legal here. In particular, the arguments may be temporary expressions +which will end up being destroyed at the end of the apparent statement, +for example: + +

+   CHECK_EQ(string("abc")[1], 'b');
+
+ +

The compiler reports an error if one of the arguments is a +pointer and the other is NULL. To work around this, simply static_cast +NULL to the type of the desired pointer. + +

+   CHECK_EQ(some_ptr, static_cast<SomeType*>(NULL));
+
+ +

Better yet, use the CHECK_NOTNULL macro: + +

+   CHECK_NOTNULL(some_ptr);
+   some_ptr->DoSomething();
+
+ +

Since this macro returns the given pointer, this is very useful in +constructor initializer lists. + +

+   struct S {
+     S(Something* ptr) : ptr_(CHECK_NOTNULL(ptr)) {}
+     Something* ptr_;
+   };
+
+ +

Note that you cannot use this macro as a C++ stream due to this +feature. Please use CHECK_EQ described above to log a +custom message before aborting the application. + +

If you are comparing C strings (char *), a handy set of macros +performs case sensitive as well as case insensitive comparisons - +CHECK_STREQ, CHECK_STRNE, +CHECK_STRCASEEQ, and CHECK_STRCASENE. The +CASE versions are case-insensitive. You can safely pass NULL +pointers for this macro. They treat NULL and any +non-NULL string as not equal. Two NULLs are +equal. + +

Note that both arguments may be temporary strings which are +destructed at the end of the current "full expression" +(e.g., CHECK_STREQ(Foo().c_str(), Bar().c_str()) where +Foo and Bar return C++'s +std::string). + +

The CHECK_DOUBLE_EQ macro checks the equality of two +floating point values, accepting a small error margin. +CHECK_NEAR accepts a third floating point argument, which +specifies the acceptable error margin. + +

Verbose Logging

+ +

When you are chasing difficult bugs, thorough log messages are very +useful. However, you may want to ignore too verbose messages in usual +development. For such verbose logging, glog provides the +VLOG macro, which allows you to define your own numeric +logging levels. The --v command line option controls +which verbose messages are logged: + +

+   VLOG(1) << "I'm printed when you run the program with --v=1 or higher";
+   VLOG(2) << "I'm printed when you run the program with --v=2 or higher";
+
+ +

With VLOG, the lower the verbose level, the more +likely messages are to be logged. For example, if +--v==1, VLOG(1) will log, but +VLOG(2) will not log. This is opposite of the severity +level, where INFO is 0, and ERROR is 2. +--minloglevel of 1 will log WARNING and +above. Though you can specify any integers for both VLOG +macro and --v flag, the common values for them are small +positive integers. For example, if you write VLOG(0), +you should specify --v=-1 or lower to silence it. This +is less useful since we may not want verbose logs by default in most +cases. The VLOG macros always log at the +INFO log level (when they log at all). + +

Verbose logging can be controlled from the command line on a +per-module basis: + +

+   --vmodule=mapreduce=2,file=1,gfs*=3 --v=0
+
+ +

will: + +

    +
  • a. Print VLOG(2) and lower messages from mapreduce.{h,cc} +
  • b. Print VLOG(1) and lower messages from file.{h,cc} +
  • c. Print VLOG(3) and lower messages from files prefixed with "gfs" +
  • d. Print VLOG(0) and lower messages from elsewhere +
+ +

The wildcarding functionality shown by (c) supports both '*' +(matches 0 or more characters) and '?' (matches any single character) +wildcards. Please also check the section about command line flags. + +

There's also VLOG_IS_ON(n) "verbose level" condition +macro. This macro returns true when the --v is equal or +greater than n. To be used as + +

+   if (VLOG_IS_ON(2)) {
+     // do some logging preparation and logging
+     // that can't be accomplished with just VLOG(2) << ...;
+   }
+
+ +

Verbose level condition macros VLOG_IF, +VLOG_EVERY_N and VLOG_IF_EVERY_N behave +analogous to LOG_IF, LOG_EVERY_N, +LOF_IF_EVERY, but accept a numeric verbosity level as +opposed to a severity level. + +

+   VLOG_IF(1, (size > 1024))
+      << "I'm printed when size is more than 1024 and when you run the "
+         "program with --v=1 or more";
+   VLOG_EVERY_N(1, 10)
+      << "I'm printed every 10th occurrence, and when you run the program "
+         "with --v=1 or more. Present occurence is " << google::COUNTER;
+   VLOG_IF_EVERY_N(1, (size > 1024), 10)
+      << "I'm printed on every 10th occurence of case when size is more "
+         " than 1024, when you run the program with --v=1 or more. ";
+         "Present occurence is " << google::COUNTER;
+
+ +

Failure Signal Handler

+ +

+The library provides a convenient signal handler that will dump useful +information when the program crashes on certain signals such as SIGSEGV. +The signal handler can be installed by +google::InstallFailureSignalHandler(). The following is an example of output +from the signal handler. + +

+*** Aborted at 1225095260 (unix time) try "date -d @1225095260" if you are using GNU date ***
+*** SIGSEGV (@0x0) received by PID 17711 (TID 0x7f893090a6f0) from PID 0; stack trace: ***
+PC: @           0x412eb1 TestWaitingLogSink::send()
+    @     0x7f892fb417d0 (unknown)
+    @           0x412eb1 TestWaitingLogSink::send()
+    @     0x7f89304f7f06 google::LogMessage::SendToLog()
+    @     0x7f89304f35af google::LogMessage::Flush()
+    @     0x7f89304f3739 google::LogMessage::~LogMessage()
+    @           0x408cf4 TestLogSinkWaitTillSent()
+    @           0x4115de main
+    @     0x7f892f7ef1c4 (unknown)
+    @           0x4046f9 (unknown)
+
+ +

+By default, the signal handler writes the failure dump to the standard +error. You can customize the destination by InstallFailureWriter(). + +

Miscellaneous Notes

+ +

Performance of Messages

+ +

The conditional logging macros provided by glog (e.g., +CHECK, LOG_IF, VLOG, ...) are +carefully implemented and don't execute the right hand side +expressions when the conditions are false. So, the following check +may not sacrifice the performance of your application. + +

+   CHECK(obj.ok) << obj.CreatePrettyFormattedStringButVerySlow();
+
+ +

User-defined Failure Function

+ +

FATAL severity level messages or unsatisfied +CHECK condition terminate your program. You can change +the behavior of the termination by +InstallFailureFunction. + +

+   void YourFailureFunction() {
+     // Reports something...
+     exit(1);
+   }
+
+   int main(int argc, char* argv[]) {
+     google::InstallFailureFunction(&YourFailureFunction);
+   }
+
+ +

By default, glog tries to dump stacktrace and makes the program +exit with status 1. The stacktrace is produced only when you run the +program on an architecture for which glog supports stack tracing (as +of September 2008, glog supports stack tracing for x86 and x86_64). + +

Raw Logging

+ +

The header file <glog/raw_logging.h> can be +used for thread-safe logging, which does not allocate any memory or +acquire any locks. Therefore, the macros defined in this +header file can be used by low-level memory allocation and +synchronization code. +Please check src/glog/raw_logging.h.in for detail. +

+ +

Google Style perror()

+ +

PLOG() and PLOG_IF() and +PCHECK() behave exactly like their LOG* and +CHECK equivalents with the addition that they append a +description of the current state of errno to their output lines. +E.g. + +

+   PCHECK(write(1, NULL, 2) >= 0) << "Write NULL failed";
+
+ +

This check fails with the following error message. + +

+   F0825 185142 test.cc:22] Check failed: write(1, NULL, 2) >= 0 Write NULL failed: Bad address [14]
+
+ +

Syslog

+ +

SYSLOG, SYSLOG_IF, and +SYSLOG_EVERY_N macros are available. +These log to syslog in addition to the normal logs. Be aware that +logging to syslog can drastically impact performance, especially if +syslog is configured for remote logging! Make sure you understand the +implications of outputting to syslog before you use these macros. In +general, it's wise to use these macros sparingly. + +

Strip Logging Messages

+ +

Strings used in log messages can increase the size of your binary +and present a privacy concern. You can therefore instruct glog to +remove all strings which fall below a certain severity level by using +the GOOGLE_STRIP_LOG macro: + +

If your application has code like this: + +

+   #define GOOGLE_STRIP_LOG 1    // this must go before the #include!
+   #include <glog/logging.h>
+
+ +

The compiler will remove the log messages whose severities are less +than the specified integer value. Since +VLOG logs at the severity level INFO +(numeric value 0), +setting GOOGLE_STRIP_LOG to 1 or greater removes +all log messages associated with VLOGs as well as +INFO log statements. + +

Notes for Windows users

+ +

Google glog defines a severity level ERROR, which is +also defined in windows.h . You can make glog not define +INFO, WARNING, ERROR, +and FATAL by defining +GLOG_NO_ABBREVIATED_SEVERITIES before +including glog/logging.h . Even with this macro, you can +still use the iostream like logging facilities: + +

+  #define GLOG_NO_ABBREVIATED_SEVERITIES
+  #include <windows.h>
+  #include <glog/logging.h>
+
+  // ...
+
+  LOG(ERROR) << "This should work";
+  LOG_IF(ERROR, x > y) << "This should be also OK";
+
+ +

+However, you cannot +use INFO, WARNING, ERROR, +and FATAL anymore for functions defined +in glog/logging.h . + +

+  #define GLOG_NO_ABBREVIATED_SEVERITIES
+  #include <windows.h>
+  #include <glog/logging.h>
+
+  // ...
+
+  // This won't work.
+  // google::FlushLogFiles(google::ERROR);
+
+  // Use this instead.
+  google::FlushLogFiles(google::GLOG_ERROR);
+
+ +

+If you don't need ERROR defined +by windows.h, there are a couple of more workarounds +which sometimes don't work: + +

    +
  • #define WIN32_LEAN_AND_MEAN or NOGDI + before you #include windows.h . +
  • #undef ERROR after you #include + windows.h . +
+ +

See +this issue for more detail. + +

Before you use this module, please give the +// name of your internal namespace for this module. Or, if you want +// to expose it, you'll want to move it to the Google namespace. We +// cannot put this class in global namespace because there can be some +// problems when we have multiple versions of Mutex in each shared object. +// +// NOTE: by default, we have #ifdef'ed out the TryLock() method. +// This is for two reasons: +// 1) TryLock() under Windows is a bit annoying (it requires a +// #define to be defined very early). +// 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG +// mode. +// If you need TryLock(), and either these two caveats are not a +// problem for you, or you're willing to work around them, then +// feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs +// in the code below. +// +// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy: +// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html +// Because of that, we might as well use windows locks for +// cygwin. They seem to be more reliable than the cygwin pthreads layer. +// +// TRICKY IMPLEMENTATION NOTE: +// This class is designed to be safe to use during +// dynamic-initialization -- that is, by global constructors that are +// run before main() starts. The issue in this case is that +// dynamic-initialization happens in an unpredictable order, and it +// could be that someone else's dynamic initializer could call a +// function that tries to acquire this mutex -- but that all happens +// before this mutex's constructor has run. (This can happen even if +// the mutex and the function that uses the mutex are in the same .cc +// file.) Basically, because Mutex does non-trivial work in its +// constructor, it's not, in the naive implementation, safe to use +// before dynamic initialization has run on it. +// +// The solution used here is to pair the actual mutex primitive with a +// bool that is set to true when the mutex is dynamically initialized. +// (Before that it's false.) Then we modify all mutex routines to +// look at the bool, and not try to lock/unlock until the bool makes +// it to true (which happens after the Mutex constructor has run.) +// +// This works because before main() starts -- particularly, during +// dynamic initialization -- there are no threads, so a) it's ok that +// the mutex operations are a no-op, since we don't need locking then +// anyway; and b) we can be quite confident our bool won't change +// state between a call to Lock() and a call to Unlock() (that would +// require a global constructor in one translation unit to call Lock() +// and another global constructor in another translation unit to call +// Unlock() later, which is pretty perverse). +// +// That said, it's tricky, and can conceivably fail; it's safest to +// avoid trying to acquire a mutex in a global constructor, if you +// can. One way it can fail is that a really smart compiler might +// initialize the bool to true at static-initialization time (too +// early) rather than at dynamic-initialization time. To discourage +// that, we set is_safe_ to true in code (not the constructor +// colon-initializer) and set it to true via a function that always +// evaluates to true, but that the compiler can't know always +// evaluates to true.

Submit a pull request. + +## The Google Test and Google Mock Communities ## + +The Google Test community exists primarily through the +[discussion group](http://groups.google.com/group/googletestframework) +and the GitHub repository. +Likewise, the Google Mock community exists primarily through their own +[discussion group](http://groups.google.com/group/googlemock). +You are definitely encouraged to contribute to the +discussion and you can also help us to keep the effectiveness of the +group high by following and promoting the guidelines listed here. + +### Please Be Friendly ### + +Showing courtesy and respect to others is a vital part of the Google +culture, and we strongly encourage everyone participating in Google +Test development to join us in accepting nothing less. Of course, +being courteous is not the same as failing to constructively disagree +with each other, but it does mean that we should be respectful of each +other when enumerating the 42 technical reasons that a particular +proposal may not be the best choice. There's never a reason to be +antagonistic or dismissive toward anyone who is sincerely trying to +contribute to a discussion. + +Sure, C++ testing is serious business and all that, but it's also +a lot of fun. Let's keep it that way. Let's strive to be one of the +friendliest communities in all of open source. + +As always, discuss Google Test in the official GoogleTest discussion group. +You don't have to actually submit code in order to sign up. Your participation +itself is a valuable contribution. + +## Style + +To keep the source consistent, readable, diffable and easy to merge, +we use a fairly rigid coding style, as defined by the [google-styleguide](https://github.com/google/styleguide) project. All patches will be expected +to conform to the style outlined [here](https://google.github.io/styleguide/cppguide.html). +Use [.clang-format](https://github.com/google/googletest/blob/master/.clang-format) to check your formatting + +## Requirements for Contributors ### + +If you plan to contribute a patch, you need to build Google Test, +Google Mock, and their own tests from a git checkout, which has +further requirements: + + * [Python](https://www.python.org/) v2.3 or newer (for running some of + the tests and re-generating certain source files from templates) + * [CMake](https://cmake.org/) v2.6.4 or newer + * [GNU Build System](https://en.wikipedia.org/wiki/GNU_Build_System) + including automake (>= 1.9), autoconf (>= 2.59), and + libtool / libtoolize. + +## Developing Google Test ## + +This section discusses how to make your own changes to Google Test. + +### Testing Google Test Itself ### + +To make sure your changes work as intended and don't break existing +functionality, you'll want to compile and run Google Test's own tests. +For that you can use CMake: + + mkdir mybuild + cd mybuild + cmake -Dgtest_build_tests=ON ${GTEST_DIR} + +Make sure you have Python installed, as some of Google Test's tests +are written in Python. If the cmake command complains about not being +able to find Python (`Could NOT find PythonInterp (missing: +PYTHON_EXECUTABLE)`), try telling it explicitly where your Python +executable can be found: + + cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR} + +Next, you can build Google Test and all of its own tests. On \*nix, +this is usually done by 'make'. To run the tests, do + + make test + +All tests should pass. + +### Regenerating Source Files ## + +Some of Google Test's source files are generated from templates (not +in the C++ sense) using a script. +For example, the +file include/gtest/internal/gtest-type-util.h.pump is used to generate +gtest-type-util.h in the same directory. + +You don't need to worry about regenerating the source files +unless you need to modify them. You would then modify the +corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)' +generator script. See the [Pump Manual](googletest/docs/PumpManual.md). + +## Developing Google Mock ### + +This section discusses how to make your own changes to Google Mock. + +#### Testing Google Mock Itself #### + +To make sure your changes work as intended and don't break existing +functionality, you'll want to compile and run Google Test's own tests. +For that you'll need Autotools. First, make sure you have followed +the instructions above to configure Google Mock. +Then, create a build output directory and enter it. Next, + + ${GMOCK_DIR}/configure # try --help for more info + +Once you have successfully configured Google Mock, the build steps are +standard for GNU-style OSS packages. + + make # Standard makefile following GNU conventions + make check # Builds and runs all tests - all should pass. + +Note that when building your project against Google Mock, you are building +against Google Test as well. There is no need to configure Google Test +separately. diff --git a/packages/google-crc32c/crc32c/third_party/googletest/LICENSE b/packages/google-crc32c/crc32c/third_party/googletest/LICENSE new file mode 100644 index 000000000000..1941a11f8ce9 --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/LICENSE @@ -0,0 +1,28 @@ +Copyright 2008, Google Inc. +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are +met: + + * Redistributions of source code must retain the above copyright +notice, this list of conditions and the following disclaimer. + * Redistributions in binary form must reproduce the above +copyright notice, this list of conditions and the following disclaimer +in the documentation and/or other materials provided with the +distribution. + * Neither the name of Google Inc. nor the names of its +contributors may be used to endorse or promote products derived from +this software without specific prior written permission. + +THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +"AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +A PARTICULAR PURPOSE ARE DISCLAIMED.

Instead, it needs a +testing framework for writing tests. Google Mock works seamlessly +with [Google Test](https://github.com/google/googletest), but +you can also use it with [any C++ testing framework](../googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework). + +### Requirements for End Users ### + +Google Mock is implemented on top of [Google Test]( +http://github.com/google/googletest/), and depends on it. +You must use the bundled version of Google Test when using Google Mock. + +You can also easily configure Google Mock to work with another testing +framework, although it will still need Google Test. Please read +["Using_Google_Mock_with_Any_Testing_Framework"]( + ../googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework) +for instructions. + +Google Mock depends on advanced C++ features and thus requires a more +modern compiler. The following are needed to use Google Mock: + +#### Linux Requirements #### + + * GNU-compatible Make or "gmake" + * POSIX-standard shell + * POSIX(-2) Regular Expressions (regex.h) + * C++98-standard-compliant compiler (e.g. GCC 3.4 or newer) + +#### Windows Requirements #### + + * Microsoft Visual C++ 8.0 SP1 or newer + +#### Mac OS X Requirements #### + + * Mac OS X 10.4 Tiger or newer + * Developer Tools Installed + +### Requirements for Contributors ### + +We welcome patches. If you plan to contribute a patch, you need to +build Google Mock and its tests, which has further requirements: + + * Automake version 1.9 or newer + * Autoconf version 2.59 or newer + * Libtool / Libtoolize + * Python version 2.3 or newer (for running some of the tests and + re-generating certain source files from templates) + +### Building Google Mock ### + +#### Using CMake #### + +If you have CMake available, it is recommended that you follow the +[build instructions][gtest_cmakebuild] +as described for Google Test. + +If are using Google Mock with an +existing CMake project, the section +[Incorporating Into An Existing CMake Project][gtest_incorpcmake] +may be of particular interest. +To make it work for Google Mock you will need to change + + target_link_libraries(example gtest_main) + +to + + target_link_libraries(example gmock_main) + +This works because `gmock_main` library is compiled with Google Test. + +#### Preparing to Build (Unix only) #### + +If you are using a Unix system and plan to use the GNU Autotools build +system to build Google Mock (described below), you'll need to +configure it now. + +To prepare the Autotools build system: + + cd googlemock + autoreconf -fvi + +To build Google Mock and your tests that use it, you need to tell your +build system where to find its headers and source files. The exact +way to do it depends on which build system you use, and is usually +straightforward. + +This section shows how you can integrate Google Mock into your +existing build system. + +Suppose you put Google Mock in directory `${GMOCK_DIR}` and Google Test +in `${GTEST_DIR}` (the latter is `${GMOCK_DIR}/gtest` by default). To +build Google Mock, create a library build target (or a project as +called by Visual Studio and Xcode) to compile + + ${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc + +with + + ${GTEST_DIR}/include and ${GMOCK_DIR}/include + +in the system header search path, and + + ${GTEST_DIR} and ${GMOCK_DIR} + +in the normal header search path. Assuming a Linux-like system and gcc, +something like the following will do: + + g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \ + -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \ + -pthread -c ${GTEST_DIR}/src/gtest-all.cc + g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \ + -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \ + -pthread -c ${GMOCK_DIR}/src/gmock-all.cc + ar -rv libgmock.a gtest-all.o gmock-all.o + +(We need -pthread as Google Test and Google Mock use threads.) + +Next, you should compile your test source file with +${GTEST\_DIR}/include and ${GMOCK\_DIR}/include in the header search +path, and link it with gmock and any other necessary libraries: + + g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \ + -pthread path/to/your_test.cc libgmock.a -o your_test + +As an example, the make/ directory contains a Makefile that you can +use to build Google Mock on systems where GNU make is available +(e.g. Linux, Mac OS X, and Cygwin). It doesn't try to build Google +Mock's own tests. Instead, it just builds the Google Mock library and +a sample test. You can use it as a starting point for your own build +script. + +If the default settings are correct for your environment, the +following commands should succeed: + + cd ${GMOCK_DIR}/make + make + ./gmock_test + +If you see errors, try to tweak the contents of +[make/Makefile](make/Makefile) to make them go away. + +### Windows ### + +The msvc/2005 directory contains VC++ 2005 projects and the msvc/2010 +directory contains VC++ 2010 projects for building Google Mock and +selected tests. + +Change to the appropriate directory and run "msbuild gmock.sln" to +build the library and tests (or open the gmock.sln in the MSVC IDE). +If you want to create your own project to use with Google Mock, you'll +have to configure it to use the `gmock_config` propety sheet. For that: + + * Open the Property Manager window (View | Other Windows | Property Manager) + * Right-click on your project and select "Add Existing Property Sheet..." + * Navigate to `gmock_config.vsprops` or `gmock_config.props` and select it. + * In Project Properties | Configuration Properties | General | Additional + Include Directories, type /include. + +### Tweaking Google Mock ### + +Google Mock can be used in diverse environments. The default +configuration may not work (or may not work well) out of the box in +some environments. However, you can easily tweak Google Mock by +defining control macros on the compiler command line. Generally, +these macros are named like `GTEST_XYZ` and you define them to either 1 +or 0 to enable or disable a certain feature. + +We list the most frequently used macros below. For a complete list, +see file [${GTEST\_DIR}/include/gtest/internal/gtest-port.h]( +../googletest/include/gtest/internal/gtest-port.h). + +### As a Shared Library (DLL) ### + +Google Mock is compact, so most users can build and link it as a static +library for the simplicity. Google Mock can be used as a DLL, but the +same DLL must contain Google Test as well. See +[Google Test's README][gtest_readme] +for instructions on how to set up necessary compiler settings. + +### Tweaking Google Mock ### + +Most of Google Test's control macros apply to Google Mock as well. +Please see [Google Test's README][gtest_readme] for how to tweak them. + +### Upgrading from an Earlier Version ### + +We strive to keep Google Mock releases backward compatible. +Sometimes, though, we have to make some breaking changes for the +users' long-term benefits. This section describes what you'll need to +do if you are upgrading from an earlier version of Google Mock. + +#### Upgrading from 1.1.0 or Earlier #### + +You may need to explicitly enable or disable Google Test's own TR1 +tuple library. See the instructions in section "[Choosing a TR1 Tuple +Library](#choosing-a-tr1-tuple-library)". + +#### Upgrading from 1.4.0 or Earlier #### + +On platforms where the pthread library is available, Google Test and +Google Mock use it in order to be thread-safe. For this to work, you +may need to tweak your compiler and/or linker flags. Please see the +"[Multi-threaded Tests](../googletest/README.md#multi-threaded-tests)" section in file Google Test's README for what you may need to do. + +If you have custom matchers defined using `MatcherInterface` or +`MakePolymorphicMatcher()`, you'll need to update their definitions to +use the new matcher API ( +[monomorphic](./docs/CookBook.md#writing-new-monomorphic-matchers), +[polymorphic](./docs/CookBook.md#writing-new-polymorphic-matchers)). +Matchers defined using `MATCHER()` or `MATCHER_P*()` aren't affected. + +Happy testing! + +[gtest_readme]: ../googletest/README.md "googletest" +[gtest_cmakebuild]: ../googletest/README.md#using-cmake "Using CMake" +[gtest_incorpcmake]: ../googletest/README.md#incorporating-into-an-existing-cmake-project "Incorporating Into An Existing CMake Project" diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/build-aux/.keep b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/build-aux/.keep new file mode 100644 index 000000000000..e69de29bb2d1 diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/cmake/gmock.pc.in b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/cmake/gmock.pc.in new file mode 100644 index 000000000000..08e0454749ba --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/cmake/gmock.pc.in @@ -0,0 +1,11 @@ +prefix=${pcfiledir}/../.. +libdir=${prefix}/@CMAKE_INSTALL_LIBDIR@ +includedir=${prefix}/@CMAKE_INSTALL_INCLUDEDIR@ + +Name: gmock +Description: GoogleMock (without main() function) +Version: @PROJECT_VERSION@ +URL: https://github.com/google/googletest +Requires: gtest +Libs: -L${libdir} -lgmock @CMAKE_THREAD_LIBS_INIT@ +Cflags: -I${includedir} @GTEST_HAS_PTHREAD_MACRO@ @CMAKE_THREAD_LIBS_INIT@ diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/cmake/gmock_main.pc.in b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/cmake/gmock_main.pc.in new file mode 100644 index 000000000000..b22fe6148283 --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/cmake/gmock_main.pc.in @@ -0,0 +1,11 @@ +prefix=${pcfiledir}/../.. +libdir=${prefix}/@CMAKE_INSTALL_LIBDIR@ +includedir=${prefix}/@CMAKE_INSTALL_INCLUDEDIR@ + +Name: gmock_main +Description: GoogleMock (with main() function) +Version: @PROJECT_VERSION@ +URL: https://github.com/google/googletest +Requires: gmock +Libs: -L${libdir} -lgmock_main @CMAKE_THREAD_LIBS_INIT@ +Cflags: -I${includedir} @GTEST_HAS_PTHREAD_MACRO@ @CMAKE_THREAD_LIBS_INIT@ diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/configure.ac b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/configure.ac new file mode 100644 index 000000000000..cb5e1a6a8cae --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/configure.ac @@ -0,0 +1,146 @@ +m4_include(../googletest/m4/acx_pthread.m4) + +AC_INIT([Google C++ Mocking Framework], + [1.8.0], + [googlemock@googlegroups.com], + [gmock]) + +# Provide various options to initialize the Autoconf and configure processes. +AC_PREREQ([2.59]) +AC_CONFIG_SRCDIR([./LICENSE]) +AC_CONFIG_AUX_DIR([build-aux]) +AC_CONFIG_HEADERS([build-aux/config.h]) +AC_CONFIG_FILES([Makefile]) +AC_CONFIG_FILES([scripts/gmock-config], [chmod +x scripts/gmock-config]) + +# Initialize Automake with various options.

For example, +```cpp + MOCK_METHOD1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int n)); + MOCK_CONST_METHOD2_WITH_CALLTYPE(STDMETHODCALLTYPE, Bar, int(double x, double y)); +``` +where `STDMETHODCALLTYPE` is defined by `` on Windows. + +# Using Mocks in Tests # + +The typical flow is: + 1. Import the Google Mock names you need to use. All Google Mock names are in the `testing` namespace unless they are macros or otherwise noted. + 1. Create the mock objects. + 1. Optionally, set the default actions of the mock objects. + 1. Set your expectations on the mock objects (How will they be called? What wil they do?). + 1. Exercise code that uses the mock objects; if necessary, check the result using [Google Test](../../googletest/) assertions. + 1. When a mock objects is destructed, Google Mock automatically verifies that all expectations on it have been satisfied. + +Here is an example: +```cpp +using ::testing::Return; // #1 + +TEST(BarTest, DoesThis) { + MockFoo foo; // #2 + + ON_CALL(foo, GetSize()) // #3 + .WillByDefault(Return(1)); + // ... other default actions ... + + EXPECT_CALL(foo, Describe(5)) // #4 + .Times(3) + .WillRepeatedly(Return("Category 5")); + // ... other expectations ... + + EXPECT_EQ("good", MyProductionFunction(&foo)); // #5 +} // #6 +``` + +# Setting Default Actions # + +Google Mock has a **built-in default action** for any function that +returns `void`, `bool`, a numeric value, or a pointer. + +To customize the default action for functions with return type `T` globally: +```cpp +using ::testing::DefaultValue; + +// Sets the default value to be returned.

T must be MoveConstructible. +// T MakeT(); +DefaultValue::SetFactory(&MakeT); +// ... use the mocks ... +// Resets the default value. +DefaultValue::Clear(); +``` + +To customize the default action for a particular method, use `ON_CALL()`: +```cpp +ON_CALL(mock_object, method(matchers)) + .With(multi_argument_matcher) ? + .WillByDefault(action); +``` + +# Setting Expectations # + +`EXPECT_CALL()` sets **expectations** on a mock method (How will it be +called?

You can use it inside +`ON_CALL()` or `EXPECT_CALL()`, or use it to validate a value +directly: + +| Matcher | Description | +|:--------|:------------| +| `EXPECT_THAT(value, matcher)` | Asserts that `value` matches `matcher`. | +| `ASSERT_THAT(value, matcher)` | The same as `EXPECT_THAT(value, matcher)`, except that it generates a **fatal** failure. | + +Built-in matchers (where `argument` is the function argument) are +divided into several categories: + +## Wildcard ## +| Matcher | Description | +|:--------|:------------| +|`_`|`argument` can be any value of the correct type.| +|`A()` or `An()`|`argument` can be any value of type `type`. | + +## Generic Comparison ## + +| Matcher | Description | +|:---------------------|:------------------| +|`Eq(value)` or `value`|`argument == value`| +|`Ge(value)` |`argument >= value`| +|`Gt(value)` |`argument > value` | +|`Le(value)` |`argument <= value`| +|`Lt(value)` |`argument < value` | +|`Ne(value)` |`argument != value`| +|`IsNull()` |`argument` is a `NULL` pointer (raw or smart).| +|`NotNull()` |`argument` is a non-null pointer (raw or smart).| +|`VariantWith(m)` |`argument` is `variant<>` that holds the alternative of type T with a value matching `m`.| +|`Ref(variable)` |`argument` is a reference to `variable`.| +|`TypedEq(value)`|`argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded.| + +Except `Ref()`, these matchers make a _copy_ of `value` in case it's +modified or destructed later. If the compiler complains that `value` +doesn't have a public copy constructor, try wrap it in `ByRef()`, +e.g. `Eq(ByRef(non_copyable_value))`. If you do that, make sure +`non_copyable_value` is not changed afterwards, or the meaning of your +matcher will be changed. + +## Floating-Point Matchers ## + +| Matcher | Description | +|:-------------------|:---------------------------------------------------------------------------------------------------------| +|`DoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal. | +|`FloatEq(a_float)` |`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. | +|`NanSensitiveDoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. | +|`NanSensitiveFloatEq(a_float)`|`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. | + +The above matchers use ULP-based comparison (the same as used in +[Google Test](../../googletest/)). They +automatically pick a reasonable error bound based on the absolute +value of the expected value. `DoubleEq()` and `FloatEq()` conform to +the IEEE standard, which requires comparing two NaNs for equality to +return false. The `NanSensitive*` version instead treats two NaNs as +equal, which is often what a user wants. + +| Matcher | Description | +|:--------|:------------| +|`DoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal.| +|`FloatNear(a_float, max_abs_error)`|`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal.| +|`NanSensitiveDoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal.| +|`NanSensitiveFloatNear(a_float, max_abs_error)`|`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal.| + +## String Matchers ## + +The `argument` can be either a C string or a C++ string object: + +| Matcher | Description | +|:----------------------|:--------------------------------------------------| +|`ContainsRegex(string)`|`argument` matches the given regular expression. | +|`EndsWith(suffix)` |`argument` ends with string `suffix`. | +|`HasSubstr(string)` |`argument` contains `string` as a sub-string. | +|`MatchesRegex(string)` |`argument` matches the given regular expression with the match starting at the first character and ending at the last character.| +|`StartsWith(prefix)` |`argument` starts with string `prefix`. | +|`StrCaseEq(string)` |`argument` is equal to `string`, ignoring case. | +|`StrCaseNe(string)` |`argument` is not equal to `string`, ignoring case.| +|`StrEq(string)` |`argument` is equal to `string`. | +|`StrNe(string)` |`argument` is not equal to `string`. | + +`ContainsRegex()` and `MatchesRegex()` use the regular expression +syntax defined +[here](../../googletest/docs/advanced.md#regular-expression-syntax). +`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide +strings as well. + +## Container Matchers ## + +Most STL-style containers support `==`, so you can use +`Eq(expected_container)` or simply `expected_container` to match a +container exactly. If you want to write the elements in-line, +match them more flexibly, or get more informative messages, you can use: + +| Matcher | Description | +|:--------|:------------| +| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. | +| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. | +| `Each(e)` | `argument` is a container where _every_ element matches `e`, which can be either a value or a matcher. | +| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the i-th element matches `ei`, which can be a value or a matcher. 0 to 10 arguments are allowed. | +| `ElementsAreArray({ e0, e1, ..., en })`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. | +| `IsEmpty()` | `argument` is an empty container (`container.empty()`). | +| `Pointwise(m, container)` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. | +| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. | +| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under some permutation each element matches an `ei` (for a different `i`), which can be a value or a matcher. 0 to 10 arguments are allowed. | +| `UnorderedElementsAreArray({ e0, e1, ..., en })`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. | +| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements `1`, `2`, and `3`, ignoring order. | +| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater(), ElementsAre(3, 2, 1))`. | + +Notes: + + * These matchers can also match: + 1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`), and + 1. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer, int len)` -- see [Multi-argument Matchers](#multiargument-matchers)). + * The array being matched may be multi-dimensional (i.e. its elements can be arrays). + * `m` in `Pointwise(m, ...)` should be a matcher for `::testing::tuple` where `T` and `U` are the element type of the actual container and the expected container, respectively. For example, to compare two `Foo` containers where `Foo` doesn't support `operator==` but has an `Equals()` method, one might write: + +```cpp +using ::testing::get; +MATCHER(FooEq, "") { + return get<0>(arg).Equals(get<1>(arg)); +} +... +EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos)); +``` + +## Member Matchers ## + +| Matcher | Description | +|:--------|:------------| +|`Field(&class::field, m)`|`argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.| +|`Key(e)`|`argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`.| +|`Pair(m1, m2)`|`argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`.| +|`Property(&class::property, m)`|`argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.| + +## Matching the Result of a Function or Functor ## + +| Matcher | Description | +|:---------------|:---------------------------------------------------------------------| +|`ResultOf(f, m)`|`f(argument)` matches matcher `m`, where `f` is a function or functor.| + +## Pointer Matchers ## + +| Matcher | Description | +|:------------------------|:-----------------------------------------------------------------------------------------------| +|`Pointee(m)` |`argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`.| +|`WhenDynamicCastTo(m)`| when `argument` is passed through `dynamic_cast()`, it matches matcher `m`. | + +## Multiargument Matchers ## + +Technically, all matchers match a _single_ value. A "multi-argument" +matcher is just one that matches a _tuple_. The following matchers can +be used to match a tuple `(x, y)`: + +| Matcher | Description | +|:--------|:------------| +|`Eq()`|`x == y`| +|`Ge()`|`x >= y`| +|`Gt()`|`x > y` | +|`Le()`|`x <= y`| +|`Lt()`|`x < y` | +|`Ne()`|`x != y`| + +You can use the following selectors to pick a subset of the arguments +(or reorder them) to participate in the matching: + +| Matcher | Description | +|:--------|:------------| +|`AllArgs(m)`|Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`.| +|`Args(m)`|The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`.| + +## Composite Matchers ## + +You can make a matcher from one or more other matchers: + +| Matcher | Description | +|:-----------------------|:------------------------------------------------------------| +|`AllOf(m1, m2, ..., mn)`|`argument` matches all of the matchers `m1` to `mn`. | +|`AnyOf(m1, m2, ..., mn)`|`argument` matches at least one of the matchers `m1` to `mn`.| +|`Not(m)` |`argument` doesn't match matcher `m`. | + +## Adapters for Matchers ## + +| Matcher | Description | +|:--------|:------------| +|`MatcherCast(m)`|casts matcher `m` to type `Matcher`.| +|`SafeMatcherCast(m)`| [safely casts](CookBook.md#casting-matchers) matcher `m` to type `Matcher`.| +|`Truly(predicate)`|`predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor.| + +## Matchers as Predicates ## + +| Matcher | Description | +|:--------|:------------| +|`Matches(m)(value)`|evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor.| +|`ExplainMatchResult(m, value, result_listener)`|evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`.| +|`Value(value, m)`|evaluates to `true` if `value` matches `m`.| + +## Defining Matchers ## + +| Matcher | Description | +|:--------|:------------| +| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. | +| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a macher `IsDivisibleBy(n)` to match a number divisible by `n`. | +| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. | + +**Notes:** + + 1. The `MATCHER*` macros cannot be used inside a function or class. + 1. The matcher body must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters). + 1. You can use `PrintToString(x)` to convert a value `x` of any type to a string. + +## Matchers as Test Assertions ## + +| Matcher | Description | +|:--------|:------------| +|`ASSERT_THAT(expression, m)`|Generates a [fatal failure](../../googletest/docs/primer.md#assertions) if the value of `expression` doesn't match matcher `m`.| +|`EXPECT_THAT(expression, m)`|Generates a non-fatal failure if the value of `expression` doesn't match matcher `m`.| + +# Actions # + +**Actions** specify what a mock function should do when invoked. + +## Returning a Value ## + +| Matcher | Description | +|:--------|:------------| +|`Return()`|Return from a `void` mock function.| +|`Return(value)`|Return `value`.

Deprecated. Will be removed in v1.7.0.| +|`SetArrayArgument(first, last)`|Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range.| +|`SetErrnoAndReturn(error, value)`|Set `errno` to `error` and return `value`.| +|`Throw(exception)`|Throws the given exception, which can be any copyable value.

+calls in the same sequence must occur in the order they are +specified. + +```cpp +using ::testing::Sequence; +Sequence s1, s2; +... +EXPECT_CALL(foo, Reset()) + .InSequence(s1, s2) + .WillOnce(Return(true)); +EXPECT_CALL(foo, GetSize()) + .InSequence(s1) + .WillOnce(Return(1)); +EXPECT_CALL(foo, Describe(A())) + .InSequence(s2) + .WillOnce(Return("dummy")); +``` +says that `Reset()` must be called before _both_ `GetSize()` _and_ +`Describe()`, and the latter two can occur in any order. + +To put many expectations in a sequence conveniently: +```cpp +using ::testing::InSequence; +{ + InSequence dummy; + + EXPECT_CALL(...)...; + EXPECT_CALL(...)...; + ... + EXPECT_CALL(...)...; +} +``` +says that all expected calls in the scope of `dummy` must occur in +strict order. The name `dummy` is irrelevant.) + +# Verifying and Resetting a Mock # + +Google Mock will verify the expectations on a mock object when it is destructed, or you can do it earlier: +```cpp +using ::testing::Mock; +... +// Verifies and removes the expectations on mock_obj; +// returns true iff successful. +Mock::VerifyAndClearExpectations(&mock_obj); +... +// Verifies and removes the expectations on mock_obj; +// also removes the default actions set by ON_CALL(); +// returns true iff successful. +Mock::VerifyAndClear(&mock_obj); +``` + +You can also tell Google Mock that a mock object can be leaked and doesn't +need to be verified: +```cpp +Mock::AllowLeak(&mock_obj); +``` + +# Mock Classes # + +Google Mock defines a convenient mock class template +```cpp +class MockFunction { + public: + MOCK_METHODn(Call, R(A1, ..., An)); +}; +``` +See this [recipe](CookBook.md#using-check-points) for one application of it. + +# Flags # + +| Flag | Description | +|:--------|:------------| +| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. | +| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. | diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/CookBook.md b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/CookBook.md new file mode 100644 index 000000000000..52091109a3c5 --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/CookBook.md @@ -0,0 +1,3660 @@ + + +You can find recipes for using Google Mock here. If you haven't yet, +please read the [ForDummies](ForDummies.md) document first to make sure you understand +the basics. + +**Note:** Google Mock lives in the `testing` name space. For +readability, it is recommended to write `using ::testing::Foo;` once in +your file before using the name `Foo` defined by Google Mock. We omit +such `using` statements in this page for brevity, but you should do it +in your own code. + +# Creating Mock Classes # + +## Mocking Private or Protected Methods ## + +You must always put a mock method definition (`MOCK_METHOD*`) in a +`public:` section of the mock class, regardless of the method being +mocked being `public`, `protected`, or `private` in the base class. +This allows `ON_CALL` and `EXPECT_CALL` to reference the mock function +from outside of the mock class. (Yes, C++ allows a subclass to specify +a different access level than the base class on a virtual function.) +Example: + +```cpp +class Foo { + public: + ... + virtual bool Transform(Gadget* g) = 0; + + protected: + virtual void Resume(); + + private: + virtual int GetTimeOut(); +}; + +class MockFoo : public Foo { + public: + ... + MOCK_METHOD1(Transform, bool(Gadget* g)); + + // The following must be in the public section, even though the + // methods are protected or private in the base class. + MOCK_METHOD0(Resume, void()); + MOCK_METHOD0(GetTimeOut, int()); +}; +``` + +## Mocking Overloaded Methods ## + +You can mock overloaded functions as usual. No special attention is required: + +```cpp +class Foo { + ... + + // Must be virtual as we'll inherit from Foo. + virtual ~Foo(); + + // Overloaded on the types and/or numbers of arguments. + virtual int Add(Element x); + virtual int Add(int times, Element x); + + // Overloaded on the const-ness of this object. + virtual Bar& GetBar(); + virtual const Bar& GetBar() const; +}; + +class MockFoo : public Foo { + ... + MOCK_METHOD1(Add, int(Element x)); + MOCK_METHOD2(Add, int(int times, Element x); + + MOCK_METHOD0(GetBar, Bar&()); + MOCK_CONST_METHOD0(GetBar, const Bar&()); +}; +``` + +**Note:** if you don't mock all versions of the overloaded method, the +compiler will give you a warning about some methods in the base class +being hidden. To fix that, use `using` to bring them in scope: + +```cpp +class MockFoo : public Foo { + ... + using Foo::Add; + MOCK_METHOD1(Add, int(Element x)); + // We don't want to mock int Add(int times, Element x); + ... +}; +``` + +## Mocking Class Templates ## + +To mock a class template, append `_T` to the `MOCK_*` macros: + +```cpp +template +class StackInterface { + ... + // Must be virtual as we'll inherit from StackInterface. + virtual ~StackInterface(); + + virtual int GetSize() const = 0; + virtual void Push(const Elem& x) = 0; +}; + +template +class MockStack : public StackInterface { + ... + MOCK_CONST_METHOD0_T(GetSize, int()); + MOCK_METHOD1_T(Push, void(const Elem& x)); +}; +``` + +## Mocking Nonvirtual Methods ## + +Google Mock can mock non-virtual functions to be used in what we call _hi-perf +dependency injection_. + +In this case, instead of sharing a common base class with the real +class, your mock class will be _unrelated_ to the real class, but +contain methods with the same signatures. The syntax for mocking +non-virtual methods is the _same_ as mocking virtual methods: + +```cpp +// A simple packet stream class. None of its members is virtual. +class ConcretePacketStream { + public: + void AppendPacket(Packet* new_packet); + const Packet* GetPacket(size_t packet_number) const; + size_t NumberOfPackets() const; + ... +}; + +// A mock packet stream class. It inherits from no other, but defines +// GetPacket() and NumberOfPackets(). +class MockPacketStream { + public: + MOCK_CONST_METHOD1(GetPacket, const Packet*(size_t packet_number)); + MOCK_CONST_METHOD0(NumberOfPackets, size_t()); + ... +}; +``` + +Note that the mock class doesn't define `AppendPacket()`, unlike the +real class. That's fine as long as the test doesn't need to call it. + +Next, you need a way to say that you want to use +`ConcretePacketStream` in production code and to use `MockPacketStream` +in tests. Since the functions are not virtual and the two classes are +unrelated, you must specify your choice at _compile time_ (as opposed +to run time). + +One way to do it is to templatize your code that needs to use a packet +stream. More specifically, you will give your code a template type +argument for the type of the packet stream. In production, you will +instantiate your template with `ConcretePacketStream` as the type +argument. In tests, you will instantiate the same template with +`MockPacketStream`. For example, you may write: + +```cpp +template +void CreateConnection(PacketStream* stream) { ... } + +template +class PacketReader { + public: + void ReadPackets(PacketStream* stream, size_t packet_num); +}; +``` + +Then you can use `CreateConnection()` and +`PacketReader` in production code, and use +`CreateConnection()` and +`PacketReader` in tests. + +```cpp + MockPacketStream mock_stream; + EXPECT_CALL(mock_stream, ...)...; + .. set more expectations on mock_stream ... + PacketReader reader(&mock_stream); + ... exercise reader ... +``` + +## Mocking Free Functions ## + +It's possible to use Google Mock to mock a free function (i.e. a +C-style function or a static method). You just need to rewrite your +code to use an interface (abstract class). + +Instead of calling a free function (say, `OpenFile`) directly, +introduce an interface for it and have a concrete subclass that calls +the free function: + +```cpp +class FileInterface { + public: + ... + virtual bool Open(const char* path, const char* mode) = 0; +}; + +class File : public FileInterface { + public: + ... + virtual bool Open(const char* path, const char* mode) { + return OpenFile(path, mode); + } +}; +``` + +Your code should talk to `FileInterface` to open a file. Now it's +easy to mock out the function. + +This may seem much hassle, but in practice you often have multiple +related functions that you can put in the same interface, so the +per-function syntactic overhead will be much lower. + +If you are concerned about the performance overhead incurred by +virtual functions, and profiling confirms your concern, you can +combine this with the recipe for [mocking non-virtual methods](#mocking-nonvirtual-methods). + +## The Nice, the Strict, and the Naggy ## + +If a mock method has no `EXPECT_CALL` spec but is called, Google Mock +will print a warning about the "uninteresting call". The rationale is: + + * New methods may be added to an interface after a test is written. We shouldn't fail a test just because a method it doesn't know about is called. + * However, this may also mean there's a bug in the test, so Google Mock shouldn't be silent either. If the user believes these calls are harmless, they can add an `EXPECT_CALL()` to suppress the warning. + +However, sometimes you may want to suppress all "uninteresting call" +warnings, while sometimes you may want the opposite, i.e. to treat all +of them as errors. Google Mock lets you make the decision on a +per-mock-object basis. + +Suppose your test uses a mock class `MockFoo`: + +```cpp +TEST(...) { + MockFoo mock_foo; + EXPECT_CALL(mock_foo, DoThis()); + ... code that uses mock_foo ... +} +``` + +If a method of `mock_foo` other than `DoThis()` is called, it will be +reported by Google Mock as a warning. However, if you rewrite your +test to use `NiceMock` instead, the warning will be gone, +resulting in a cleaner test output: + +```cpp +using ::testing::NiceMock; + +TEST(...) { + NiceMock mock_foo; + EXPECT_CALL(mock_foo, DoThis()); + ... code that uses mock_foo ... +} +``` + +`NiceMock` is a subclass of `MockFoo`, so it can be used +wherever `MockFoo` is accepted. + +It also works if `MockFoo`'s constructor takes some arguments, as +`NiceMock` "inherits" `MockFoo`'s constructors: + +```cpp +using ::testing::NiceMock; + +TEST(...) { + NiceMock mock_foo(5, "hi"); // Calls MockFoo(5, "hi"). + EXPECT_CALL(mock_foo, DoThis()); + ... code that uses mock_foo ... +} +``` + +The usage of `StrictMock` is similar, except that it makes all +uninteresting calls failures: + +```cpp +using ::testing::StrictMock; + +TEST(...) { + StrictMock mock_foo; + EXPECT_CALL(mock_foo, DoThis()); + ... code that uses mock_foo ... + + // The test will fail if a method of mock_foo other than DoThis() + // is called. +} +``` + +There are some caveats though (I don't like them just as much as the +next guy, but sadly they are side effects of C++'s limitations): + + 1. `NiceMock` and `StrictMock` only work for mock methods defined using the `MOCK_METHOD*` family of macros **directly** in the `MockFoo` class. If a mock method is defined in a **base class** of `MockFoo`, the "nice" or "strict" modifier may not affect it, depending on the compiler. In particular, nesting `NiceMock` and `StrictMock` (e.g. `NiceMock >`) is **not** supported. + 1. The constructors of the base mock (`MockFoo`) cannot have arguments passed by non-const reference, which happens to be banned by the [Google C++ style guide](https://google.github.io/styleguide/cppguide.html). + 1. During the constructor or destructor of `MockFoo`, the mock object is _not_ nice or strict. This may cause surprises if the constructor or destructor calls a mock method on `this` object. (This behavior, however, is consistent with C++'s general rule: if a constructor or destructor calls a virtual method of `this` object, that method is treated as non-virtual. In other words, to the base class's constructor or destructor, `this` object behaves like an instance of the base class, not the derived class. This rule is required for safety. Otherwise a base constructor may use members of a derived class before they are initialized, or a base destructor may use members of a derived class after they have been destroyed.) + +Finally, you should be **very cautious** about when to use naggy or strict mocks, as they tend to make tests more brittle and harder to maintain. When you refactor your code without changing its externally visible behavior, ideally you should't need to update any tests. If your code interacts with a naggy mock, however, you may start to get spammed with warnings as the result of your change. Worse, if your code interacts with a strict mock, your tests may start to fail and you'll be forced to fix them. Our general recommendation is to use nice mocks (not yet the default) most of the time, use naggy mocks (the current default) when developing or debugging tests, and use strict mocks only as the last resort. + +## Simplifying the Interface without Breaking Existing Code ## + +Sometimes a method has a long list of arguments that is mostly +uninteresting. For example, + +```cpp +class LogSink { + public: + ... + virtual void send(LogSeverity severity, const char* full_filename, + const char* base_filename, int line, + const struct tm* tm_time, + const char* message, size_t message_len) = 0; +}; +``` + +This method's argument list is lengthy and hard to work with (let's +say that the `message` argument is not even 0-terminated). If we mock +it as is, using the mock will be awkward. If, however, we try to +simplify this interface, we'll need to fix all clients depending on +it, which is often infeasible. + +The trick is to re-dispatch the method in the mock class: + +```cpp +class ScopedMockLog : public LogSink { + public: + ... + virtual void send(LogSeverity severity, const char* full_filename, + const char* base_filename, int line, const tm* tm_time, + const char* message, size_t message_len) { + // We are only interested in the log severity, full file name, and + // log message. + Log(severity, full_filename, std::string(message, message_len)); + } + + // Implements the mock method: + // + // void Log(LogSeverity severity, + // const string& file_path, + // const string& message); + MOCK_METHOD3(Log, void(LogSeverity severity, const string& file_path, + const string& message)); +}; +``` + +By defining a new mock method with a trimmed argument list, we make +the mock class much more user-friendly. + +## Alternative to Mocking Concrete Classes ## + +Often you may find yourself using classes that don't implement +interfaces. In order to test your code that uses such a class (let's +call it `Concrete`), you may be tempted to make the methods of +`Concrete` virtual and then mock it. + +Try not to do that. + +Making a non-virtual function virtual is a big decision. It creates an +extension point where subclasses can tweak your class' behavior. This +weakens your control on the class because now it's harder to maintain +the class' invariants. You should make a function virtual only when +there is a valid reason for a subclass to override it. + +Mocking concrete classes directly is problematic as it creates a tight +coupling between the class and the tests - any small change in the +class may invalidate your tests and make test maintenance a pain. + +To avoid such problems, many programmers have been practicing "coding +to interfaces": instead of talking to the `Concrete` class, your code +would define an interface and talk to it. Then you implement that +interface as an adaptor on top of `Concrete`. In tests, you can easily +mock that interface to observe how your code is doing. + +This technique incurs some overhead: + + * You pay the cost of virtual function calls (usually not a problem). + * There is more abstraction for the programmers to learn. + +However, it can also bring significant benefits in addition to better +testability: + + * `Concrete`'s API may not fit your problem domain very well, as you may not be the only client it tries to serve. By designing your own interface, you have a chance to tailor it to your need - you may add higher-level functionalities, rename stuff, etc instead of just trimming the class. This allows you to write your code (user of the interface) in a more natural way, which means it will be more readable, more maintainable, and you'll be more productive. + * If `Concrete`'s implementation ever has to change, you don't have to rewrite everywhere it is used. Instead, you can absorb the change in your implementation of the interface, and your other code and tests will be insulated from this change. + +Some people worry that if everyone is practicing this technique, they +will end up writing lots of redundant code. This concern is totally +understandable. However, there are two reasons why it may not be the +case: + + * Different projects may need to use `Concrete` in different ways, so the best interfaces for them will be different. Therefore, each of them will have its own domain-specific interface on top of `Concrete`, and they will not be the same code. + * If enough projects want to use the same interface, they can always share it, just like they have been sharing `Concrete`. You can check in the interface and the adaptor somewhere near `Concrete` (perhaps in a `contrib` sub-directory) and let many projects use it. + +You need to weigh the pros and cons carefully for your particular +problem, but I'd like to assure you that the Java community has been +practicing this for a long time and it's a proven effective technique +applicable in a wide variety of situations. :-) + +## Delegating Calls to a Fake ## + +Some times you have a non-trivial fake implementation of an +interface. For example: + +```cpp +class Foo { + public: + virtual ~Foo() {} + virtual char DoThis(int n) = 0; + virtual void DoThat(const char* s, int* p) = 0; +}; + +class FakeFoo : public Foo { + public: + virtual char DoThis(int n) { + return (n > 0) ? '+' : + (n < 0) ? '-' : '0'; + } + + virtual void DoThat(const char* s, int* p) { + *p = strlen(s); + } +}; +``` + +Now you want to mock this interface such that you can set expectations +on it. However, you also want to use `FakeFoo` for the default +behavior, as duplicating it in the mock object is, well, a lot of +work. + +When you define the mock class using Google Mock, you can have it +delegate its default action to a fake class you already have, using +this pattern: + +```cpp +using ::testing::_; +using ::testing::Invoke; + +class MockFoo : public Foo { + public: + // Normal mock method definitions using Google Mock. + MOCK_METHOD1(DoThis, char(int n)); + MOCK_METHOD2(DoThat, void(const char* s, int* p)); + + // Delegates the default actions of the methods to a FakeFoo object. + // This must be called *before* the custom ON_CALL() statements. + void DelegateToFake() { + ON_CALL(*this, DoThis(_)) + .WillByDefault(Invoke(&fake_, &FakeFoo::DoThis)); + ON_CALL(*this, DoThat(_, _)) + .WillByDefault(Invoke(&fake_, &FakeFoo::DoThat)); + } + private: + FakeFoo fake_; // Keeps an instance of the fake in the mock. +}; +``` + +With that, you can use `MockFoo` in your tests as usual. Just remember +that if you don't explicitly set an action in an `ON_CALL()` or +`EXPECT_CALL()`, the fake will be called upon to do it: + +```cpp +using ::testing::_; + +TEST(AbcTest, Xyz) { + MockFoo foo; + foo.DelegateToFake(); // Enables the fake for delegation. + + // Put your ON_CALL(foo, ...)s here, if any. + + // No action specified, meaning to use the default action. + EXPECT_CALL(foo, DoThis(5)); + EXPECT_CALL(foo, DoThat(_, _)); + + int n = 0; + EXPECT_EQ('+', foo.DoThis(5)); // FakeFoo::DoThis() is invoked. + foo.DoThat("Hi", &n); // FakeFoo::DoThat() is invoked. + EXPECT_EQ(2, n); +} +``` + +**Some tips:** + + * If you want, you can still override the default action by providing your own `ON_CALL()` or using `.WillOnce()` / `.WillRepeatedly()` in `EXPECT_CALL()`. + * In `DelegateToFake()`, you only need to delegate the methods whose fake implementation you intend to use. + * The general technique discussed here works for overloaded methods, but you'll need to tell the compiler which version you mean. To disambiguate a mock function (the one you specify inside the parentheses of `ON_CALL()`), see the "Selecting Between Overloaded Functions" section on this page; to disambiguate a fake function (the one you place inside `Invoke()`), use a `static_cast` to specify the function's type. For instance, if class `Foo` has methods `char DoThis(int n)` and `bool DoThis(double x) const`, and you want to invoke the latter, you need to write `Invoke(&fake_, static_cast(&FakeFoo::DoThis))` instead of `Invoke(&fake_, &FakeFoo::DoThis)` (The strange-looking thing inside the angled brackets of `static_cast` is the type of a function pointer to the second `DoThis()` method.). + * Having to mix a mock and a fake is often a sign of something gone wrong. Perhaps you haven't got used to the interaction-based way of testing yet. Or perhaps your interface is taking on too many roles and should be split up. Therefore, **don't abuse this**. We would only recommend to do it as an intermediate step when you are refactoring your code. + +Regarding the tip on mixing a mock and a fake, here's an example on +why it may be a bad sign: Suppose you have a class `System` for +low-level system operations. In particular, it does file and I/O +operations. And suppose you want to test how your code uses `System` +to do I/O, and you just want the file operations to work normally. If +you mock out the entire `System` class, you'll have to provide a fake +implementation for the file operation part, which suggests that +`System` is taking on too many roles. + +Instead, you can define a `FileOps` interface and an `IOOps` interface +and split `System`'s functionalities into the two. Then you can mock +`IOOps` without mocking `FileOps`. + +## Delegating Calls to a Real Object ## + +When using testing doubles (mocks, fakes, stubs, and etc), sometimes +their behaviors will differ from those of the real objects. This +difference could be either intentional (as in simulating an error such +that you can test the error handling code) or unintentional. If your +mocks have different behaviors than the real objects by mistake, you +could end up with code that passes the tests but fails in production. + +You can use the _delegating-to-real_ technique to ensure that your +mock has the same behavior as the real object while retaining the +ability to validate calls. This technique is very similar to the +delegating-to-fake technique, the difference being that we use a real +object instead of a fake. Here's an example: + +```cpp +using ::testing::_; +using ::testing::AtLeast; +using ::testing::Invoke; + +class MockFoo : public Foo { + public: + MockFoo() { + // By default, all calls are delegated to the real object. + ON_CALL(*this, DoThis()) + .WillByDefault(Invoke(&real_, &Foo::DoThis)); + ON_CALL(*this, DoThat(_)) + .WillByDefault(Invoke(&real_, &Foo::DoThat)); + ... + } + MOCK_METHOD0(DoThis, ...); + MOCK_METHOD1(DoThat, ...); + ... + private: + Foo real_; +}; +... + + MockFoo mock; + + EXPECT_CALL(mock, DoThis()) + .Times(3); + EXPECT_CALL(mock, DoThat("Hi")) + .Times(AtLeast(1)); + ... use mock in test ... +``` + +With this, Google Mock will verify that your code made the right calls +(with the right arguments, in the right order, called the right number +of times, etc), and a real object will answer the calls (so the +behavior will be the same as in production). This gives you the best +of both worlds. + +## Delegating Calls to a Parent Class ## + +Ideally, you should code to interfaces, whose methods are all pure +virtual. In reality, sometimes you do need to mock a virtual method +that is not pure (i.e, it already has an implementation). For example: + +```cpp +class Foo { + public: + virtual ~Foo(); + + virtual void Pure(int n) = 0; + virtual int Concrete(const char* str) { ... } +}; + +class MockFoo : public Foo { + public: + // Mocking a pure method. + MOCK_METHOD1(Pure, void(int n)); + // Mocking a concrete method. Foo::Concrete() is shadowed. + MOCK_METHOD1(Concrete, int(const char* str)); +}; +``` + +Sometimes you may want to call `Foo::Concrete()` instead of +`MockFoo::Concrete()`. Perhaps you want to do it as part of a stub +action, or perhaps your test doesn't need to mock `Concrete()` at all +(but it would be oh-so painful to have to define a new mock class +whenever you don't need to mock one of its methods). + +The trick is to leave a back door in your mock class for accessing the +real methods in the base class: + +```cpp +class MockFoo : public Foo { + public: + // Mocking a pure method. + MOCK_METHOD1(Pure, void(int n)); + // Mocking a concrete method. Foo::Concrete() is shadowed. + MOCK_METHOD1(Concrete, int(const char* str)); + + // Use this to call Concrete() defined in Foo. + int FooConcrete(const char* str) { return Foo::Concrete(str); } +}; +``` + +Now, you can call `Foo::Concrete()` inside an action by: + +```cpp +using ::testing::_; +using ::testing::Invoke; +... + EXPECT_CALL(foo, Concrete(_)) + .WillOnce(Invoke(&foo, &MockFoo::FooConcrete)); +``` + +or tell the mock object that you don't want to mock `Concrete()`: + +```cpp +using ::testing::Invoke; +... + ON_CALL(foo, Concrete(_)) + .WillByDefault(Invoke(&foo, &MockFoo::FooConcrete)); +``` + +(Why don't we just write `Invoke(&foo, &Foo::Concrete)`? If you do +that, `MockFoo::Concrete()` will be called (and cause an infinite +recursion) since `Foo::Concrete()` is virtual. That's just how C++ +works.) + +# Using Matchers # + +## Matching Argument Values Exactly ## + +You can specify exactly which arguments a mock method is expecting: + +```cpp +using ::testing::Return; +... + EXPECT_CALL(foo, DoThis(5)) + .WillOnce(Return('a')); + EXPECT_CALL(foo, DoThat("Hello", bar)); +``` + +## Using Simple Matchers ## + +You can use matchers to match arguments that have a certain property: + +```cpp +using ::testing::Ge; +using ::testing::NotNull; +using ::testing::Return; +... + EXPECT_CALL(foo, DoThis(Ge(5))) // The argument must be >= 5. + .WillOnce(Return('a')); + EXPECT_CALL(foo, DoThat("Hello", NotNull())); + // The second argument must not be NULL. +``` + +A frequently used matcher is `_`, which matches anything: + +```cpp +using ::testing::_; +using ::testing::NotNull; +... + EXPECT_CALL(foo, DoThat(_, NotNull())); +``` + +## Combining Matchers ## + +You can build complex matchers from existing ones using `AllOf()`, +`AnyOf()`, and `Not()`: + +```cpp +using ::testing::AllOf; +using ::testing::Gt; +using ::testing::HasSubstr; +using ::testing::Ne; +using ::testing::Not; +... + // The argument must be > 5 and != 10. + EXPECT_CALL(foo, DoThis(AllOf(Gt(5), + Ne(10)))); + + // The first argument must not contain sub-string "blah". + EXPECT_CALL(foo, DoThat(Not(HasSubstr("blah")), + NULL)); +``` + +## Casting Matchers ## + +Google Mock matchers are statically typed, meaning that the compiler +can catch your mistake if you use a matcher of the wrong type (for +example, if you use `Eq(5)` to match a `string` argument). Good for +you! + +Sometimes, however, you know what you're doing and want the compiler +to give you some slack. One example is that you have a matcher for +`long` and the argument you want to match is `int`. While the two +types aren't exactly the same, there is nothing really wrong with +using a `Matcher` to match an `int` - after all, we can first +convert the `int` argument to a `long` before giving it to the +matcher. + +To support this need, Google Mock gives you the +`SafeMatcherCast(m)` function. It casts a matcher `m` to type +`Matcher`. To ensure safety, Google Mock checks that (let `U` be the +type `m` accepts): + + 1. Type `T` can be implicitly cast to type `U`; + 1. When both `T` and `U` are built-in arithmetic types (`bool`, integers, and floating-point numbers), the conversion from `T` to `U` is not lossy (in other words, any value representable by `T` can also be represented by `U`); and + 1. When `U` is a reference, `T` must also be a reference (as the underlying matcher may be interested in the address of the `U` value). + +The code won't compile if any of these conditions aren't met. + +Here's one example: + +```cpp +using ::testing::SafeMatcherCast; + +// A base class and a child class. +class Base { ... }; +class Derived : public Base { ... }; + +class MockFoo : public Foo { + public: + MOCK_METHOD1(DoThis, void(Derived* derived)); +}; +... + + MockFoo foo; + // m is a Matcher we got from somewhere. + EXPECT_CALL(foo, DoThis(SafeMatcherCast(m))); +``` + +If you find `SafeMatcherCast(m)` too limiting, you can use a similar +function `MatcherCast(m)`. The difference is that `MatcherCast` works +as long as you can `static_cast` type `T` to type `U`. + +`MatcherCast` essentially lets you bypass C++'s type system +(`static_cast` isn't always safe as it could throw away information, +for example), so be careful not to misuse/abuse it. + +## Selecting Between Overloaded Functions ## + +If you expect an overloaded function to be called, the compiler may +need some help on which overloaded version it is. + +To disambiguate functions overloaded on the const-ness of this object, +use the `Const()` argument wrapper. + +```cpp +using ::testing::ReturnRef; + +class MockFoo : public Foo { + ... + MOCK_METHOD0(GetBar, Bar&()); + MOCK_CONST_METHOD0(GetBar, const Bar&()); +}; +... + + MockFoo foo; + Bar bar1, bar2; + EXPECT_CALL(foo, GetBar()) // The non-const GetBar(). + .WillOnce(ReturnRef(bar1)); + EXPECT_CALL(Const(foo), GetBar()) // The const GetBar(). + .WillOnce(ReturnRef(bar2)); +``` + +(`Const()` is defined by Google Mock and returns a `const` reference +to its argument.) + +To disambiguate overloaded functions with the same number of arguments +but different argument types, you may need to specify the exact type +of a matcher, either by wrapping your matcher in `Matcher()`, or +using a matcher whose type is fixed (`TypedEq`, `An()`, +etc): + +```cpp +using ::testing::An; +using ::testing::Lt; +using ::testing::Matcher; +using ::testing::TypedEq; + +class MockPrinter : public Printer { + public: + MOCK_METHOD1(Print, void(int n)); + MOCK_METHOD1(Print, void(char c)); +}; + +TEST(PrinterTest, Print) { + MockPrinter printer; + + EXPECT_CALL(printer, Print(An())); // void Print(int); + EXPECT_CALL(printer, Print(Matcher(Lt(5)))); // void Print(int); + EXPECT_CALL(printer, Print(TypedEq('a'))); // void Print(char); + + printer.Print(3); + printer.Print(6); + printer.Print('a'); +} +``` + +## Performing Different Actions Based on the Arguments ## + +When a mock method is called, the _last_ matching expectation that's +still active will be selected (think "newer overrides older"). So, you +can make a method do different things depending on its argument values +like this: + +```cpp +using ::testing::_; +using ::testing::Lt; +using ::testing::Return; +... + // The default case. + EXPECT_CALL(foo, DoThis(_)) + .WillRepeatedly(Return('b')); + + // The more specific case. + EXPECT_CALL(foo, DoThis(Lt(5))) + .WillRepeatedly(Return('a')); +``` + +Now, if `foo.DoThis()` is called with a value less than 5, `'a'` will +be returned; otherwise `'b'` will be returned. + +## Matching Multiple Arguments as a Whole ## + +Sometimes it's not enough to match the arguments individually. For +example, we may want to say that the first argument must be less than +the second argument. The `With()` clause allows us to match +all arguments of a mock function as a whole. For example, + +```cpp +using ::testing::_; +using ::testing::Lt; +using ::testing::Ne; +... + EXPECT_CALL(foo, InRange(Ne(0), _)) + .With(Lt()); +``` + +says that the first argument of `InRange()` must not be 0, and must be +less than the second argument. + +The expression inside `With()` must be a matcher of type +`Matcher< ::testing::tuple >`, where `A1`, ..., `An` are the +types of the function arguments. + +You can also write `AllArgs(m)` instead of `m` inside `.With()`. The +two forms are equivalent, but `.With(AllArgs(Lt()))` is more readable +than `.With(Lt())`. + +You can use `Args(m)` to match the `n` selected arguments +(as a tuple) against `m`. For example, + +```cpp +using ::testing::_; +using ::testing::AllOf; +using ::testing::Args; +using ::testing::Lt; +... + EXPECT_CALL(foo, Blah(_, _, _)) + .With(AllOf(Args<0, 1>(Lt()), Args<1, 2>(Lt()))); +``` + +says that `Blah()` will be called with arguments `x`, `y`, and `z` where +`x < y < z`. + +As a convenience and example, Google Mock provides some matchers for +2-tuples, including the `Lt()` matcher above. See the [CheatSheet](CheatSheet.md) for +the complete list. + +Note that if you want to pass the arguments to a predicate of your own +(e.g. `.With(Args<0, 1>(Truly(&MyPredicate)))`), that predicate MUST be +written to take a `::testing::tuple` as its argument; Google Mock will pass the `n` selected arguments as _one_ single tuple to the predicate. + +## Using Matchers as Predicates ## + +Have you noticed that a matcher is just a fancy predicate that also +knows how to describe itself? Many existing algorithms take predicates +as arguments (e.g. those defined in STL's `` header), and +it would be a shame if Google Mock matchers are not allowed to +participate. + +Luckily, you can use a matcher where a unary predicate functor is +expected by wrapping it inside the `Matches()` function. For example, + +```cpp +#include +#include + +std::vector v; +... +// How many elements in v are >= 10? +const int count = count_if(v.begin(), v.end(), Matches(Ge(10))); +``` + +Since you can build complex matchers from simpler ones easily using +Google Mock, this gives you a way to conveniently construct composite +predicates (doing the same using STL's `` header is just +painful). For example, here's a predicate that's satisfied by any +number that is >= 0, <= 100, and != 50: + +```cpp +Matches(AllOf(Ge(0), Le(100), Ne(50))) +``` + +## Using Matchers in Google Test Assertions ## + +Since matchers are basically predicates that also know how to describe +themselves, there is a way to take advantage of them in +[Google Test](../../googletest/) assertions. It's +called `ASSERT_THAT` and `EXPECT_THAT`: + +```cpp + ASSERT_THAT(value, matcher); // Asserts that value matches matcher. + EXPECT_THAT(value, matcher); // The non-fatal version. +``` + +For example, in a Google Test test you can write: + +```cpp +#include "gmock/gmock.h" + +using ::testing::AllOf; +using ::testing::Ge; +using ::testing::Le; +using ::testing::MatchesRegex; +using ::testing::StartsWith; +... + + EXPECT_THAT(Foo(), StartsWith("Hello")); + EXPECT_THAT(Bar(), MatchesRegex("Line \\d+")); + ASSERT_THAT(Baz(), AllOf(Ge(5), Le(10))); +``` + +which (as you can probably guess) executes `Foo()`, `Bar()`, and +`Baz()`, and verifies that: + + * `Foo()` returns a string that starts with `"Hello"`. + * `Bar()` returns a string that matches regular expression `"Line \\d+"`. + * `Baz()` returns a number in the range [5, 10]. + +The nice thing about these macros is that _they read like +English_. They generate informative messages too. For example, if the +first `EXPECT_THAT()` above fails, the message will be something like: + +``` +Value of: Foo() + Actual: "Hi, world!" +Expected: starts with "Hello" +``` + +**Credit:** The idea of `(ASSERT|EXPECT)_THAT` was stolen from the +[Hamcrest](https://github.com/hamcrest/) project, which adds +`assertThat()` to JUnit. + +## Using Predicates as Matchers ## + +Google Mock provides a built-in set of matchers. In case you find them +lacking, you can use an arbitray unary predicate function or functor +as a matcher - as long as the predicate accepts a value of the type +you want. You do this by wrapping the predicate inside the `Truly()` +function, for example: + +```cpp +using ::testing::Truly; + +int IsEven(int n) { return (n % 2) == 0 ? 1 : 0; } +... + + // Bar() must be called with an even number. + EXPECT_CALL(foo, Bar(Truly(IsEven))); +``` + +Note that the predicate function / functor doesn't have to return +`bool`. It works as long as the return value can be used as the +condition in statement `if (condition) ...`. + +## Matching Arguments that Are Not Copyable ## + +When you do an `EXPECT_CALL(mock_obj, Foo(bar))`, Google Mock saves +away a copy of `bar`. When `Foo()` is called later, Google Mock +compares the argument to `Foo()` with the saved copy of `bar`. This +way, you don't need to worry about `bar` being modified or destroyed +after the `EXPECT_CALL()` is executed. The same is true when you use +matchers like `Eq(bar)`, `Le(bar)`, and so on. + +But what if `bar` cannot be copied (i.e. has no copy constructor)? You +could define your own matcher function and use it with `Truly()`, as +the previous couple of recipes have shown. Or, you may be able to get +away from it if you can guarantee that `bar` won't be changed after +the `EXPECT_CALL()` is executed. Just tell Google Mock that it should +save a reference to `bar`, instead of a copy of it. Here's how: + +```cpp +using ::testing::Eq; +using ::testing::ByRef; +using ::testing::Lt; +... + // Expects that Foo()'s argument == bar. + EXPECT_CALL(mock_obj, Foo(Eq(ByRef(bar)))); + + // Expects that Foo()'s argument < bar. + EXPECT_CALL(mock_obj, Foo(Lt(ByRef(bar)))); +``` + +Remember: if you do this, don't change `bar` after the +`EXPECT_CALL()`, or the result is undefined. + +## Validating a Member of an Object ## + +Often a mock function takes a reference to object as an argument. When +matching the argument, you may not want to compare the entire object +against a fixed object, as that may be over-specification. Instead, +you may need to validate a certain member variable or the result of a +certain getter method of the object. You can do this with `Field()` +and `Property()`. More specifically, + +```cpp +Field(&Foo::bar, m) +``` + +is a matcher that matches a `Foo` object whose `bar` member variable +satisfies matcher `m`. + +```cpp +Property(&Foo::baz, m) +``` + +is a matcher that matches a `Foo` object whose `baz()` method returns +a value that satisfies matcher `m`. + +For example: + +| Expression | Description | +|:-----------------------------|:-----------------------------------| +| `Field(&Foo::number, Ge(3))` | Matches `x` where `x.number >= 3`. | +| `Property(&Foo::name, StartsWith("John "))` | Matches `x` where `x.name()` starts with `"John "`. | + +Note that in `Property(&Foo::baz, ...)`, method `baz()` must take no +argument and be declared as `const`. + +BTW, `Field()` and `Property()` can also match plain pointers to +objects. For instance, + +```cpp +Field(&Foo::number, Ge(3)) +``` + +matches a plain pointer `p` where `p->number >= 3`. If `p` is `NULL`, +the match will always fail regardless of the inner matcher. + +What if you want to validate more than one members at the same time? +Remember that there is `AllOf()`. + +## Validating the Value Pointed to by a Pointer Argument ## + +C++ functions often take pointers as arguments. You can use matchers +like `IsNull()`, `NotNull()`, and other comparison matchers to match a +pointer, but what if you want to make sure the value _pointed to_ by +the pointer, instead of the pointer itself, has a certain property? +Well, you can use the `Pointee(m)` matcher. + +`Pointee(m)` matches a pointer iff `m` matches the value the pointer +points to. For example: + +```cpp +using ::testing::Ge; +using ::testing::Pointee; +... + EXPECT_CALL(foo, Bar(Pointee(Ge(3)))); +``` + +expects `foo.Bar()` to be called with a pointer that points to a value +greater than or equal to 3. + +One nice thing about `Pointee()` is that it treats a `NULL` pointer as +a match failure, so you can write `Pointee(m)` instead of + +```cpp + AllOf(NotNull(), Pointee(m)) +``` + +without worrying that a `NULL` pointer will crash your test. + +Also, did we tell you that `Pointee()` works with both raw pointers +**and** smart pointers (`linked_ptr`, `shared_ptr`, `scoped_ptr`, and +etc)? + +What if you have a pointer to pointer? You guessed it - you can use +nested `Pointee()` to probe deeper inside the value. For example, +`Pointee(Pointee(Lt(3)))` matches a pointer that points to a pointer +that points to a number less than 3 (what a mouthful...). + +## Testing a Certain Property of an Object ## + +Sometimes you want to specify that an object argument has a certain +property, but there is no existing matcher that does this. If you want +good error messages, you should define a matcher. If you want to do it +quick and dirty, you could get away with writing an ordinary function. + +Let's say you have a mock function that takes an object of type `Foo`, +which has an `int bar()` method and an `int baz()` method, and you +want to constrain that the argument's `bar()` value plus its `baz()` +value is a given number. Here's how you can define a matcher to do it: + +```cpp +using ::testing::MatcherInterface; +using ::testing::MatchResultListener; + +class BarPlusBazEqMatcher : public MatcherInterface { + public: + explicit BarPlusBazEqMatcher(int expected_sum) + : expected_sum_(expected_sum) {} + + virtual bool MatchAndExplain(const Foo& foo, + MatchResultListener* listener) const { + return (foo.bar() + foo.baz()) == expected_sum_; + } + + virtual void DescribeTo(::std::ostream* os) const { + *os << "bar() + baz() equals " << expected_sum_; + } + + virtual void DescribeNegationTo(::std::ostream* os) const { + *os << "bar() + baz() does not equal " << expected_sum_; + } + private: + const int expected_sum_; +}; + +inline Matcher BarPlusBazEq(int expected_sum) { + return MakeMatcher(new BarPlusBazEqMatcher(expected_sum)); +} + +... + + EXPECT_CALL(..., DoThis(BarPlusBazEq(5)))...; +``` + +## Matching Containers ## + +Sometimes an STL container (e.g. list, vector, map, ...) is passed to +a mock function and you may want to validate it. Since most STL +containers support the `==` operator, you can write +`Eq(expected_container)` or simply `expected_container` to match a +container exactly. + +Sometimes, though, you may want to be more flexible (for example, the +first element must be an exact match, but the second element can be +any positive number, and so on). Also, containers used in tests often +have a small number of elements, and having to define the expected +container out-of-line is a bit of a hassle. + +You can use the `ElementsAre()` or `UnorderedElementsAre()` matcher in +such cases: + +```cpp +using ::testing::_; +using ::testing::ElementsAre; +using ::testing::Gt; +... + + MOCK_METHOD1(Foo, void(const vector& numbers)); +... + + EXPECT_CALL(mock, Foo(ElementsAre(1, Gt(0), _, 5))); +``` + +The above matcher says that the container must have 4 elements, which +must be 1, greater than 0, anything, and 5 respectively. + +If you instead write: + +```cpp +using ::testing::_; +using ::testing::Gt; +using ::testing::UnorderedElementsAre; +... + + MOCK_METHOD1(Foo, void(const vector& numbers)); +... + + EXPECT_CALL(mock, Foo(UnorderedElementsAre(1, Gt(0), _, 5))); +``` + +It means that the container must have 4 elements, which under some +permutation must be 1, greater than 0, anything, and 5 respectively. + +`ElementsAre()` and `UnorderedElementsAre()` are overloaded to take 0 +to 10 arguments. If more are needed, you can place them in a C-style +array and use `ElementsAreArray()` or `UnorderedElementsAreArray()` +instead: + +```cpp +using ::testing::ElementsAreArray; +... + + // ElementsAreArray accepts an array of element values. + const int expected_vector1[] = { 1, 5, 2, 4, ... }; + EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector1))); + + // Or, an array of element matchers. + Matcher expected_vector2 = { 1, Gt(2), _, 3, ... }; + EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector2))); +``` + +In case the array needs to be dynamically created (and therefore the +array size cannot be inferred by the compiler), you can give +`ElementsAreArray()` an additional argument to specify the array size: + +```cpp +using ::testing::ElementsAreArray; +... + int* const expected_vector3 = new int[count]; + ... fill expected_vector3 with values ... + EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector3, count))); +``` + +**Tips:** + + * `ElementsAre*()` can be used to match _any_ container that implements the STL iterator pattern (i.e. it has a `const_iterator` type and supports `begin()/end()`), not just the ones defined in STL. It will even work with container types yet to be written - as long as they follows the above pattern. + * You can use nested `ElementsAre*()` to match nested (multi-dimensional) containers. + * If the container is passed by pointer instead of by reference, just write `Pointee(ElementsAre*(...))`. + * The order of elements _matters_ for `ElementsAre*()`. Therefore don't use it with containers whose element order is undefined (e.g. `hash_map`). + +## Sharing Matchers ## + +Under the hood, a Google Mock matcher object consists of a pointer to +a ref-counted implementation object. Copying matchers is allowed and +very efficient, as only the pointer is copied. When the last matcher +that references the implementation object dies, the implementation +object will be deleted. + +Therefore, if you have some complex matcher that you want to use again +and again, there is no need to build it every time. Just assign it to a +matcher variable and use that variable repeatedly! For example, + +```cpp + Matcher in_range = AllOf(Gt(5), Le(10)); + ... use in_range as a matcher in multiple EXPECT_CALLs ... +``` + +# Setting Expectations # + +## Knowing When to Expect ## + +`ON_CALL` is likely the single most under-utilized construct in Google Mock. + +There are basically two constructs for defining the behavior of a mock object: `ON_CALL` and `EXPECT_CALL`. The difference? `ON_CALL` defines what happens when a mock method is called, but _doesn't imply any expectation on the method being called._ `EXPECT_CALL` not only defines the behavior, but also sets an expectation that _the method will be called with the given arguments, for the given number of times_ (and _in the given order_ when you specify the order too). + +Since `EXPECT_CALL` does more, isn't it better than `ON_CALL`? Not really. Every `EXPECT_CALL` adds a constraint on the behavior of the code under test. Having more constraints than necessary is _baaad_ - even worse than not having enough constraints. + +This may be counter-intuitive. How could tests that verify more be worse than tests that verify less? Isn't verification the whole point of tests? + +The answer, lies in _what_ a test should verify. **A good test verifies the contract of the code.** If a test over-specifies, it doesn't leave enough freedom to the implementation. As a result, changing the implementation without breaking the contract (e.g. refactoring and optimization), which should be perfectly fine to do, can break such tests. Then you have to spend time fixing them, only to see them broken again the next time the implementation is changed. + +Keep in mind that one doesn't have to verify more than one property in one test. In fact, **it's a good style to verify only one thing in one test.** If you do that, a bug will likely break only one or two tests instead of dozens (which case would you rather debug?). If you are also in the habit of giving tests descriptive names that tell what they verify, you can often easily guess what's wrong just from the test log itself. + +So use `ON_CALL` by default, and only use `EXPECT_CALL` when you actually intend to verify that the call is made. For example, you may have a bunch of `ON_CALL`s in your test fixture to set the common mock behavior shared by all tests in the same group, and write (scarcely) different `EXPECT_CALL`s in different `TEST_F`s to verify different aspects of the code's behavior. Compared with the style where each `TEST` has many `EXPECT_CALL`s, this leads to tests that are more resilient to implementational changes (and thus less likely to require maintenance) and makes the intent of the tests more obvious (so they are easier to maintain when you do need to maintain them). + +If you are bothered by the "Uninteresting mock function call" message printed when a mock method without an `EXPECT_CALL` is called, you may use a `NiceMock` instead to suppress all such messages for the mock object, or suppress the message for specific methods by adding `EXPECT_CALL(...).Times(AnyNumber())`. DO NOT suppress it by blindly adding an `EXPECT_CALL(...)`, or you'll have a test that's a pain to maintain. + +## Ignoring Uninteresting Calls ## + +If you are not interested in how a mock method is called, just don't +say anything about it. In this case, if the method is ever called, +Google Mock will perform its default action to allow the test program +to continue. If you are not happy with the default action taken by +Google Mock, you can override it using `DefaultValue::Set()` +(described later in this document) or `ON_CALL()`. + +Please note that once you expressed interest in a particular mock +method (via `EXPECT_CALL()`), all invocations to it must match some +expectation. If this function is called but the arguments don't match +any `EXPECT_CALL()` statement, it will be an error. + +## Disallowing Unexpected Calls ## + +If a mock method shouldn't be called at all, explicitly say so: + +```cpp +using ::testing::_; +... + EXPECT_CALL(foo, Bar(_)) + .Times(0); +``` + +If some calls to the method are allowed, but the rest are not, just +list all the expected calls: + +```cpp +using ::testing::AnyNumber; +using ::testing::Gt; +... + EXPECT_CALL(foo, Bar(5)); + EXPECT_CALL(foo, Bar(Gt(10))) + .Times(AnyNumber()); +``` + +A call to `foo.Bar()` that doesn't match any of the `EXPECT_CALL()` +statements will be an error. + +## Understanding Uninteresting vs Unexpected Calls ## + +_Uninteresting_ calls and _unexpected_ calls are different concepts in Google Mock. _Very_ different. + +A call `x.Y(...)` is **uninteresting** if there's _not even a single_ `EXPECT_CALL(x, Y(...))` set. In other words, the test isn't interested in the `x.Y()` method at all, as evident in that the test doesn't care to say anything about it. + +A call `x.Y(...)` is **unexpected** if there are some `EXPECT_CALL(x, Y(...))s` set, but none of them matches the call. Put another way, the test is interested in the `x.Y()` method (therefore it _explicitly_ sets some `EXPECT_CALL` to verify how it's called); however, the verification fails as the test doesn't expect this particular call to happen. + +**An unexpected call is always an error,** as the code under test doesn't behave the way the test expects it to behave. + +**By default, an uninteresting call is not an error,** as it violates no constraint specified by the test. (Google Mock's philosophy is that saying nothing means there is no constraint.) However, it leads to a warning, as it _might_ indicate a problem (e.g. the test author might have forgotten to specify a constraint). + +In Google Mock, `NiceMock` and `StrictMock` can be used to make a mock class "nice" or "strict". How does this affect uninteresting calls and unexpected calls? + +A **nice mock** suppresses uninteresting call warnings. It is less chatty than the default mock, but otherwise is the same. If a test fails with a default mock, it will also fail using a nice mock instead. And vice versa. Don't expect making a mock nice to change the test's result. + +A **strict mock** turns uninteresting call warnings into errors. So making a mock strict may change the test's result. + +Let's look at an example: + +```cpp +TEST(...) { + NiceMock mock_registry; + EXPECT_CALL(mock_registry, GetDomainOwner("google.com")) + .WillRepeatedly(Return("Larry Page")); + + // Use mock_registry in code under test. + ... &mock_registry ... +} +``` + +The sole `EXPECT_CALL` here says that all calls to `GetDomainOwner()` must have `"google.com"` as the argument. If `GetDomainOwner("yahoo.com")` is called, it will be an unexpected call, and thus an error. Having a nice mock doesn't change the severity of an unexpected call. + +So how do we tell Google Mock that `GetDomainOwner()` can be called with some other arguments as well? The standard technique is to add a "catch all" `EXPECT_CALL`: + +```cpp + EXPECT_CALL(mock_registry, GetDomainOwner(_)) + .Times(AnyNumber()); // catches all other calls to this method. + EXPECT_CALL(mock_registry, GetDomainOwner("google.com")) + .WillRepeatedly(Return("Larry Page")); +``` + +Remember that `_` is the wildcard matcher that matches anything. With this, if `GetDomainOwner("google.com")` is called, it will do what the second `EXPECT_CALL` says; if it is called with a different argument, it will do what the first `EXPECT_CALL` says. + +Note that the order of the two `EXPECT_CALLs` is important, as a newer `EXPECT_CALL` takes precedence over an older one. + +For more on uninteresting calls, nice mocks, and strict mocks, read ["The Nice, the Strict, and the Naggy"](#the-nice-the-strict-and-the-naggy). + +## Expecting Ordered Calls ## + +Although an `EXPECT_CALL()` statement defined earlier takes precedence +when Google Mock tries to match a function call with an expectation, +by default calls don't have to happen in the order `EXPECT_CALL()` +statements are written. For example, if the arguments match the +matchers in the third `EXPECT_CALL()`, but not those in the first two, +then the third expectation will be used. + +If you would rather have all calls occur in the order of the +expectations, put the `EXPECT_CALL()` statements in a block where you +define a variable of type `InSequence`: + +```cpp + using ::testing::_; + using ::testing::InSequence; + + { + InSequence s; + + EXPECT_CALL(foo, DoThis(5)); + EXPECT_CALL(bar, DoThat(_)) + .Times(2); + EXPECT_CALL(foo, DoThis(6)); + } +``` + +In this example, we expect a call to `foo.DoThis(5)`, followed by two +calls to `bar.DoThat()` where the argument can be anything, which are +in turn followed by a call to `foo.DoThis(6)`. If a call occurred +out-of-order, Google Mock will report an error. + +## Expecting Partially Ordered Calls ## + +Sometimes requiring everything to occur in a predetermined order can +lead to brittle tests. For example, we may care about `A` occurring +before both `B` and `C`, but aren't interested in the relative order +of `B` and `C`. In this case, the test should reflect our real intent, +instead of being overly constraining. + +Google Mock allows you to impose an arbitrary DAG (directed acyclic +graph) on the calls. One way to express the DAG is to use the +[After](CheatSheet.md#the-after-clause) clause of `EXPECT_CALL`. + +Another way is via the `InSequence()` clause (not the same as the +`InSequence` class), which we borrowed from jMock 2. It's less +flexible than `After()`, but more convenient when you have long chains +of sequential calls, as it doesn't require you to come up with +different names for the expectations in the chains. Here's how it +works: + +If we view `EXPECT_CALL()` statements as nodes in a graph, and add an +edge from node A to node B wherever A must occur before B, we can get +a DAG. We use the term "sequence" to mean a directed path in this +DAG. Now, if we decompose the DAG into sequences, we just need to know +which sequences each `EXPECT_CALL()` belongs to in order to be able to +reconstruct the original DAG. + +So, to specify the partial order on the expectations we need to do two +things: first to define some `Sequence` objects, and then for each +`EXPECT_CALL()` say which `Sequence` objects it is part +of. Expectations in the same sequence must occur in the order they are +written. For example, + +```cpp + using ::testing::Sequence; + + Sequence s1, s2; + + EXPECT_CALL(foo, A()) + .InSequence(s1, s2); + EXPECT_CALL(bar, B()) + .InSequence(s1); + EXPECT_CALL(bar, C()) + .InSequence(s2); + EXPECT_CALL(foo, D()) + .InSequence(s2); +``` + +specifies the following DAG (where `s1` is `A -> B`, and `s2` is `A -> +C -> D`): + +``` + +---> B + | + A ---| + | + +---> C ---> D +``` + +This means that A must occur before B and C, and C must occur before +D. There's no restriction about the order other than these. + +## Controlling When an Expectation Retires ## + +When a mock method is called, Google Mock only consider expectations +that are still active. An expectation is active when created, and +becomes inactive (aka _retires_) when a call that has to occur later +has occurred. For example, in + +```cpp + using ::testing::_; + using ::testing::Sequence; + + Sequence s1, s2; + + EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #1 + .Times(AnyNumber()) + .InSequence(s1, s2); + EXPECT_CALL(log, Log(WARNING, _, "Data set is empty.")) // #2 + .InSequence(s1); + EXPECT_CALL(log, Log(WARNING, _, "User not found.")) // #3 + .InSequence(s2); +``` + +as soon as either #2 or #3 is matched, #1 will retire. If a warning +`"File too large."` is logged after this, it will be an error. + +Note that an expectation doesn't retire automatically when it's +saturated. For example, + +```cpp +using ::testing::_; +... + EXPECT_CALL(log, Log(WARNING, _, _)); // #1 + EXPECT_CALL(log, Log(WARNING, _, "File too large.")); // #2 +``` + +says that there will be exactly one warning with the message `"File +too large."`. If the second warning contains this message too, #2 will +match again and result in an upper-bound-violated error. + +If this is not what you want, you can ask an expectation to retire as +soon as it becomes saturated: + +```cpp +using ::testing::_; +... + EXPECT_CALL(log, Log(WARNING, _, _)); // #1 + EXPECT_CALL(log, Log(WARNING, _, "File too large.")) // #2 + .RetiresOnSaturation(); +``` + +Here #2 can be used only once, so if you have two warnings with the +message `"File too large."`, the first will match #2 and the second +will match #1 - there will be no error. + +# Using Actions # + +## Returning References from Mock Methods ## + +If a mock function's return type is a reference, you need to use +`ReturnRef()` instead of `Return()` to return a result: + +```cpp +using ::testing::ReturnRef; + +class MockFoo : public Foo { + public: + MOCK_METHOD0(GetBar, Bar&()); +}; +... + + MockFoo foo; + Bar bar; + EXPECT_CALL(foo, GetBar()) + .WillOnce(ReturnRef(bar)); +``` + +## Returning Live Values from Mock Methods ## + +The `Return(x)` action saves a copy of `x` when the action is +_created_, and always returns the same value whenever it's +executed. Sometimes you may want to instead return the _live_ value of +`x` (i.e. its value at the time when the action is _executed_.). + +If the mock function's return type is a reference, you can do it using +`ReturnRef(x)`, as shown in the previous recipe ("Returning References +from Mock Methods"). However, Google Mock doesn't let you use +`ReturnRef()` in a mock function whose return type is not a reference, +as doing that usually indicates a user error. So, what shall you do? + +You may be tempted to try `ByRef()`: + +```cpp +using testing::ByRef; +using testing::Return; + +class MockFoo : public Foo { + public: + MOCK_METHOD0(GetValue, int()); +}; +... + int x = 0; + MockFoo foo; + EXPECT_CALL(foo, GetValue()) + .WillRepeatedly(Return(ByRef(x))); + x = 42; + EXPECT_EQ(42, foo.GetValue()); +``` + +Unfortunately, it doesn't work here. The above code will fail with error: + +``` +Value of: foo.GetValue() + Actual: 0 +Expected: 42 +``` + +The reason is that `Return(value)` converts `value` to the actual +return type of the mock function at the time when the action is +_created_, not when it is _executed_. (This behavior was chosen for +the action to be safe when `value` is a proxy object that references +some temporary objects.) As a result, `ByRef(x)` is converted to an +`int` value (instead of a `const int&`) when the expectation is set, +and `Return(ByRef(x))` will always return 0. + +`ReturnPointee(pointer)` was provided to solve this problem +specifically. It returns the value pointed to by `pointer` at the time +the action is _executed_: + +```cpp +using testing::ReturnPointee; +... + int x = 0; + MockFoo foo; + EXPECT_CALL(foo, GetValue()) + .WillRepeatedly(ReturnPointee(&x)); // Note the & here. + x = 42; + EXPECT_EQ(42, foo.GetValue()); // This will succeed now. +``` + +## Combining Actions ## + +Want to do more than one thing when a function is called? That's +fine. `DoAll()` allow you to do sequence of actions every time. Only +the return value of the last action in the sequence will be used. + +```cpp +using ::testing::DoAll; + +class MockFoo : public Foo { + public: + MOCK_METHOD1(Bar, bool(int n)); +}; +... + + EXPECT_CALL(foo, Bar(_)) + .WillOnce(DoAll(action_1, + action_2, + ... + action_n)); +``` + +## Mocking Side Effects ## + +Sometimes a method exhibits its effect not via returning a value but +via side effects. For example, it may change some global state or +modify an output argument. To mock side effects, in general you can +define your own action by implementing `::testing::ActionInterface`. + +If all you need to do is to change an output argument, the built-in +`SetArgPointee()` action is convenient: + +```cpp +using ::testing::SetArgPointee; + +class MockMutator : public Mutator { + public: + MOCK_METHOD2(Mutate, void(bool mutate, int* value)); + ... +}; +... + + MockMutator mutator; + EXPECT_CALL(mutator, Mutate(true, _)) + .WillOnce(SetArgPointee<1>(5)); +``` + +In this example, when `mutator.Mutate()` is called, we will assign 5 +to the `int` variable pointed to by argument #1 +(0-based). + +`SetArgPointee()` conveniently makes an internal copy of the +value you pass to it, removing the need to keep the value in scope and +alive. The implication however is that the value must have a copy +constructor and assignment operator. + +If the mock method also needs to return a value as well, you can chain +`SetArgPointee()` with `Return()` using `DoAll()`: + +```cpp +using ::testing::_; +using ::testing::Return; +using ::testing::SetArgPointee; + +class MockMutator : public Mutator { + public: + ... + MOCK_METHOD1(MutateInt, bool(int* value)); +}; +... + + MockMutator mutator; + EXPECT_CALL(mutator, MutateInt(_)) + .WillOnce(DoAll(SetArgPointee<0>(5), + Return(true))); +``` + +If the output argument is an array, use the +`SetArrayArgument(first, last)` action instead. It copies the +elements in source range `[first, last)` to the array pointed to by +the `N`-th (0-based) argument: + +```cpp +using ::testing::NotNull; +using ::testing::SetArrayArgument; + +class MockArrayMutator : public ArrayMutator { + public: + MOCK_METHOD2(Mutate, void(int* values, int num_values)); + ... +}; +... + + MockArrayMutator mutator; + int values[5] = { 1, 2, 3, 4, 5 }; + EXPECT_CALL(mutator, Mutate(NotNull(), 5)) + .WillOnce(SetArrayArgument<0>(values, values + 5)); +``` + +This also works when the argument is an output iterator: + +```cpp +using ::testing::_; +using ::testing::SetArrayArgument; + +class MockRolodex : public Rolodex { + public: + MOCK_METHOD1(GetNames, void(std::back_insert_iterator >)); + ... +}; +... + + MockRolodex rolodex; + vector names; + names.push_back("George"); + names.push_back("John"); + names.push_back("Thomas"); + EXPECT_CALL(rolodex, GetNames(_)) + .WillOnce(SetArrayArgument<0>(names.begin(), names.end())); +``` + +## Changing a Mock Object's Behavior Based on the State ## + +If you expect a call to change the behavior of a mock object, you can use `::testing::InSequence` to specify different behaviors before and after the call: + +```cpp +using ::testing::InSequence; +using ::testing::Return; + +... + { + InSequence seq; + EXPECT_CALL(my_mock, IsDirty()) + .WillRepeatedly(Return(true)); + EXPECT_CALL(my_mock, Flush()); + EXPECT_CALL(my_mock, IsDirty()) + .WillRepeatedly(Return(false)); + } + my_mock.FlushIfDirty(); +``` + +This makes `my_mock.IsDirty()` return `true` before `my_mock.Flush()` is called and return `false` afterwards. + +If the behavior change is more complex, you can store the effects in a variable and make a mock method get its return value from that variable: + +```cpp +using ::testing::_; +using ::testing::SaveArg; +using ::testing::Return; + +ACTION_P(ReturnPointee, p) { return *p; } +... + int previous_value = 0; + EXPECT_CALL(my_mock, GetPrevValue()) + .WillRepeatedly(ReturnPointee(&previous_value)); + EXPECT_CALL(my_mock, UpdateValue(_)) + .WillRepeatedly(SaveArg<0>(&previous_value)); + my_mock.DoSomethingToUpdateValue(); +``` + +Here `my_mock.GetPrevValue()` will always return the argument of the last `UpdateValue()` call. + +## Setting the Default Value for a Return Type ## + +If a mock method's return type is a built-in C++ type or pointer, by +default it will return 0 when invoked. Also, in C++ 11 and above, a mock +method whose return type has a default constructor will return a default-constructed +value by default. You only need to specify an +action if this default value doesn't work for you. + +Sometimes, you may want to change this default value, or you may want +to specify a default value for types Google Mock doesn't know +about. You can do this using the `::testing::DefaultValue` class +template: + +```cpp +class MockFoo : public Foo { + public: + MOCK_METHOD0(CalculateBar, Bar()); +}; +... + + Bar default_bar; + // Sets the default return value for type Bar. + DefaultValue::Set(default_bar); + + MockFoo foo; + + // We don't need to specify an action here, as the default + // return value works for us. + EXPECT_CALL(foo, CalculateBar()); + + foo.CalculateBar(); // This should return default_bar. + + // Unsets the default return value. + DefaultValue::Clear(); +``` + +Please note that changing the default value for a type can make you +tests hard to understand. We recommend you to use this feature +judiciously. For example, you may want to make sure the `Set()` and +`Clear()` calls are right next to the code that uses your mock. + +## Setting the Default Actions for a Mock Method ## + +You've learned how to change the default value of a given +type. However, this may be too coarse for your purpose: perhaps you +have two mock methods with the same return type and you want them to +have different behaviors. The `ON_CALL()` macro allows you to +customize your mock's behavior at the method level: + +```cpp +using ::testing::_; +using ::testing::AnyNumber; +using ::testing::Gt; +using ::testing::Return; +... + ON_CALL(foo, Sign(_)) + .WillByDefault(Return(-1)); + ON_CALL(foo, Sign(0)) + .WillByDefault(Return(0)); + ON_CALL(foo, Sign(Gt(0))) + .WillByDefault(Return(1)); + + EXPECT_CALL(foo, Sign(_)) + .Times(AnyNumber()); + + foo.Sign(5); // This should return 1. + foo.Sign(-9); // This should return -1. + foo.Sign(0); // This should return 0. +``` + +As you may have guessed, when there are more than one `ON_CALL()` +statements, the news order take precedence over the older ones. In +other words, the **last** one that matches the function arguments will +be used. This matching order allows you to set up the common behavior +in a mock object's constructor or the test fixture's set-up phase and +specialize the mock's behavior later. + +## Using Functions/Methods/Functors as Actions ## + +If the built-in actions don't suit you, you can easily use an existing +function, method, or functor as an action: + +```cpp +using ::testing::_; +using ::testing::Invoke; + +class MockFoo : public Foo { + public: + MOCK_METHOD2(Sum, int(int x, int y)); + MOCK_METHOD1(ComplexJob, bool(int x)); +}; + +int CalculateSum(int x, int y) { return x + y; } + +class Helper { + public: + bool ComplexJob(int x); +}; +... + + MockFoo foo; + Helper helper; + EXPECT_CALL(foo, Sum(_, _)) + .WillOnce(Invoke(CalculateSum)); + EXPECT_CALL(foo, ComplexJob(_)) + .WillOnce(Invoke(&helper, &Helper::ComplexJob)); + + foo.Sum(5, 6); // Invokes CalculateSum(5, 6). + foo.ComplexJob(10); // Invokes helper.ComplexJob(10); +``` + +The only requirement is that the type of the function, etc must be +_compatible_ with the signature of the mock function, meaning that the +latter's arguments can be implicitly converted to the corresponding +arguments of the former, and the former's return type can be +implicitly converted to that of the latter. So, you can invoke +something whose type is _not_ exactly the same as the mock function, +as long as it's safe to do so - nice, huh? + +## Invoking a Function/Method/Functor Without Arguments ## + +`Invoke()` is very useful for doing actions that are more complex. It +passes the mock function's arguments to the function or functor being +invoked such that the callee has the full context of the call to work +with. If the invoked function is not interested in some or all of the +arguments, it can simply ignore them. + +Yet, a common pattern is that a test author wants to invoke a function +without the arguments of the mock function. `Invoke()` allows her to +do that using a wrapper function that throws away the arguments before +invoking an underlining nullary function. Needless to say, this can be +tedious and obscures the intent of the test. + +`InvokeWithoutArgs()` solves this problem. It's like `Invoke()` except +that it doesn't pass the mock function's arguments to the +callee. Here's an example: + +```cpp +using ::testing::_; +using ::testing::InvokeWithoutArgs; + +class MockFoo : public Foo { + public: + MOCK_METHOD1(ComplexJob, bool(int n)); +}; + +bool Job1() { ... } +... + + MockFoo foo; + EXPECT_CALL(foo, ComplexJob(_)) + .WillOnce(InvokeWithoutArgs(Job1)); + + foo.ComplexJob(10); // Invokes Job1(). +``` + +## Invoking an Argument of the Mock Function ## + +Sometimes a mock function will receive a function pointer or a functor +(in other words, a "callable") as an argument, e.g. + +```cpp +class MockFoo : public Foo { + public: + MOCK_METHOD2(DoThis, bool(int n, bool (*fp)(int))); +}; +``` + +and you may want to invoke this callable argument: + +```cpp +using ::testing::_; +... + MockFoo foo; + EXPECT_CALL(foo, DoThis(_, _)) + .WillOnce(...); + // Will execute (*fp)(5), where fp is the + // second argument DoThis() receives. +``` + +Arghh, you need to refer to a mock function argument but your version +of C++ has no lambdas, so you have to define your own action. :-( +Or do you really? + +Well, Google Mock has an action to solve _exactly_ this problem: + +```cpp + InvokeArgument(arg_1, arg_2, ..., arg_m) +``` + +will invoke the `N`-th (0-based) argument the mock function receives, +with `arg_1`, `arg_2`, ..., and `arg_m`. No matter if the argument is +a function pointer or a functor, Google Mock handles them both. + +With that, you could write: + +```cpp +using ::testing::_; +using ::testing::InvokeArgument; +... + EXPECT_CALL(foo, DoThis(_, _)) + .WillOnce(InvokeArgument<1>(5)); + // Will execute (*fp)(5), where fp is the + // second argument DoThis() receives. +``` + +What if the callable takes an argument by reference? No problem - just +wrap it inside `ByRef()`: + +```cpp +... + MOCK_METHOD1(Bar, bool(bool (*fp)(int, const Helper&))); +... +using ::testing::_; +using ::testing::ByRef; +using ::testing::InvokeArgument; +... + + MockFoo foo; + Helper helper; + ... + EXPECT_CALL(foo, Bar(_)) + .WillOnce(InvokeArgument<0>(5, ByRef(helper))); + // ByRef(helper) guarantees that a reference to helper, not a copy of it, + // will be passed to the callable. +``` + +What if the callable takes an argument by reference and we do **not** +wrap the argument in `ByRef()`? Then `InvokeArgument()` will _make a +copy_ of the argument, and pass a _reference to the copy_, instead of +a reference to the original value, to the callable. This is especially +handy when the argument is a temporary value: + +```cpp +... + MOCK_METHOD1(DoThat, bool(bool (*f)(const double& x, const string& s))); +... +using ::testing::_; +using ::testing::InvokeArgument; +... + + MockFoo foo; + ... + EXPECT_CALL(foo, DoThat(_)) + .WillOnce(InvokeArgument<0>(5.0, string("Hi"))); + // Will execute (*f)(5.0, string("Hi")), where f is the function pointer + // DoThat() receives. Note that the values 5.0 and string("Hi") are + // temporary and dead once the EXPECT_CALL() statement finishes. Yet + // it's fine to perform this action later, since a copy of the values + // are kept inside the InvokeArgument action. +``` + +## Ignoring an Action's Result ## + +Sometimes you have an action that returns _something_, but you need an +action that returns `void` (perhaps you want to use it in a mock +function that returns `void`, or perhaps it needs to be used in +`DoAll()` and it's not the last in the list). `IgnoreResult()` lets +you do that. For example: + +```cpp +using ::testing::_; +using ::testing::Invoke; +using ::testing::Return; + +int Process(const MyData& data); +string DoSomething(); + +class MockFoo : public Foo { + public: + MOCK_METHOD1(Abc, void(const MyData& data)); + MOCK_METHOD0(Xyz, bool()); +}; +... + + MockFoo foo; + EXPECT_CALL(foo, Abc(_)) + // .WillOnce(Invoke(Process)); + // The above line won't compile as Process() returns int but Abc() needs + // to return void. + .WillOnce(IgnoreResult(Invoke(Process))); + + EXPECT_CALL(foo, Xyz()) + .WillOnce(DoAll(IgnoreResult(Invoke(DoSomething)), + // Ignores the string DoSomething() returns. + Return(true))); +``` + +Note that you **cannot** use `IgnoreResult()` on an action that already +returns `void`. Doing so will lead to ugly compiler errors. + +## Selecting an Action's Arguments ## + +Say you have a mock function `Foo()` that takes seven arguments, and +you have a custom action that you want to invoke when `Foo()` is +called. Trouble is, the custom action only wants three arguments: + +```cpp +using ::testing::_; +using ::testing::Invoke; +... + MOCK_METHOD7(Foo, bool(bool visible, const string& name, int x, int y, + const map, double>& weight, + double min_weight, double max_wight)); +... + +bool IsVisibleInQuadrant1(bool visible, int x, int y) { + return visible && x >= 0 && y >= 0; +} +... + + EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _)) + .WillOnce(Invoke(IsVisibleInQuadrant1)); // Uh, won't compile. :-( +``` + +To please the compiler God, you can to define an "adaptor" that has +the same signature as `Foo()` and calls the custom action with the +right arguments: + +```cpp +using ::testing::_; +using ::testing::Invoke; + +bool MyIsVisibleInQuadrant1(bool visible, const string& name, int x, int y, + const map, double>& weight, + double min_weight, double max_wight) { + return IsVisibleInQuadrant1(visible, x, y); +} +... + + EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _)) + .WillOnce(Invoke(MyIsVisibleInQuadrant1)); // Now it works. +``` + +But isn't this awkward? + +Google Mock provides a generic _action adaptor_, so you can spend your +time minding more important business than writing your own +adaptors. Here's the syntax: + +```cpp + WithArgs(action) +``` + +creates an action that passes the arguments of the mock function at +the given indices (0-based) to the inner `action` and performs +it. Using `WithArgs`, our original example can be written as: + +```cpp +using ::testing::_; +using ::testing::Invoke; +using ::testing::WithArgs; +... + EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _)) + .WillOnce(WithArgs<0, 2, 3>(Invoke(IsVisibleInQuadrant1))); + // No need to define your own adaptor. +``` + +For better readability, Google Mock also gives you: + + * `WithoutArgs(action)` when the inner `action` takes _no_ argument, and + * `WithArg(action)` (no `s` after `Arg`) when the inner `action` takes _one_ argument. + +As you may have realized, `InvokeWithoutArgs(...)` is just syntactic +sugar for `WithoutArgs(Invoke(...))`. + +Here are more tips: + + * The inner action used in `WithArgs` and friends does not have to be `Invoke()` -- it can be anything. + * You can repeat an argument in the argument list if necessary, e.g. `WithArgs<2, 3, 3, 5>(...)`. + * You can change the order of the arguments, e.g. `WithArgs<3, 2, 1>(...)`. + * The types of the selected arguments do _not_ have to match the signature of the inner action exactly. It works as long as they can be implicitly converted to the corresponding arguments of the inner action. For example, if the 4-th argument of the mock function is an `int` and `my_action` takes a `double`, `WithArg<4>(my_action)` will work. + +## Ignoring Arguments in Action Functions ## + +The selecting-an-action's-arguments recipe showed us one way to make a +mock function and an action with incompatible argument lists fit +together. The downside is that wrapping the action in +`WithArgs<...>()` can get tedious for people writing the tests. + +If you are defining a function, method, or functor to be used with +`Invoke*()`, and you are not interested in some of its arguments, an +alternative to `WithArgs` is to declare the uninteresting arguments as +`Unused`. This makes the definition less cluttered and less fragile in +case the types of the uninteresting arguments change. It could also +increase the chance the action function can be reused. For example, +given + +```cpp + MOCK_METHOD3(Foo, double(const string& label, double x, double y)); + MOCK_METHOD3(Bar, double(int index, double x, double y)); +``` + +instead of + +```cpp +using ::testing::_; +using ::testing::Invoke; + +double DistanceToOriginWithLabel(const string& label, double x, double y) { + return sqrt(x*x + y*y); +} + +double DistanceToOriginWithIndex(int index, double x, double y) { + return sqrt(x*x + y*y); +} +... + + EXEPCT_CALL(mock, Foo("abc", _, _)) + .WillOnce(Invoke(DistanceToOriginWithLabel)); + EXEPCT_CALL(mock, Bar(5, _, _)) + .WillOnce(Invoke(DistanceToOriginWithIndex)); +``` + +you could write + +```cpp +using ::testing::_; +using ::testing::Invoke; +using ::testing::Unused; + +double DistanceToOrigin(Unused, double x, double y) { + return sqrt(x*x + y*y); +} +... + + EXEPCT_CALL(mock, Foo("abc", _, _)) + .WillOnce(Invoke(DistanceToOrigin)); + EXEPCT_CALL(mock, Bar(5, _, _)) + .WillOnce(Invoke(DistanceToOrigin)); +``` + +## Sharing Actions ## + +Just like matchers, a Google Mock action object consists of a pointer +to a ref-counted implementation object. Therefore copying actions is +also allowed and very efficient. When the last action that references +the implementation object dies, the implementation object will be +deleted. + +If you have some complex action that you want to use again and again, +you may not have to build it from scratch every time. If the action +doesn't have an internal state (i.e. if it always does the same thing +no matter how many times it has been called), you can assign it to an +action variable and use that variable repeatedly. For example: + +```cpp + Action set_flag = DoAll(SetArgPointee<0>(5), + Return(true)); + ... use set_flag in .WillOnce() and .WillRepeatedly() ... +``` + +However, if the action has its own state, you may be surprised if you +share the action object. Suppose you have an action factory +`IncrementCounter(init)` which creates an action that increments and +returns a counter whose initial value is `init`, using two actions +created from the same expression and using a shared action will +exihibit different behaviors. Example: + +```cpp + EXPECT_CALL(foo, DoThis()) + .WillRepeatedly(IncrementCounter(0)); + EXPECT_CALL(foo, DoThat()) + .WillRepeatedly(IncrementCounter(0)); + foo.DoThis(); // Returns 1. + foo.DoThis(); // Returns 2. + foo.DoThat(); // Returns 1 - Blah() uses a different + // counter than Bar()'s. +``` + +versus + +```cpp + Action increment = IncrementCounter(0); + + EXPECT_CALL(foo, DoThis()) + .WillRepeatedly(increment); + EXPECT_CALL(foo, DoThat()) + .WillRepeatedly(increment); + foo.DoThis(); // Returns 1. + foo.DoThis(); // Returns 2. + foo.DoThat(); // Returns 3 - the counter is shared. +``` + +# Misc Recipes on Using Google Mock # + +## Mocking Methods That Use Move-Only Types ## + +C++11 introduced *move-only types*. A move-only-typed value can be moved from +one object to another, but cannot be copied. `std::unique_ptr` is +probably the most commonly used move-only type. + +Mocking a method that takes and/or returns move-only types presents some +challenges, but nothing insurmountable. This recipe shows you how you can do it. +Note that the support for move-only method arguments was only introduced to +gMock in April 2017; in older code, you may find more complex +[workarounds](#legacy-workarounds-for-move-only-types) for lack of this feature. + +Let’s say we are working on a fictional project that lets one post and share +snippets called “buzzes”. Your code uses these types: + +```cpp +enum class AccessLevel { kInternal, kPublic }; + +class Buzz { + public: + explicit Buzz(AccessLevel access) { ... } + ... +}; + +class Buzzer { + public: + virtual ~Buzzer() {} + virtual std::unique_ptr MakeBuzz(StringPiece text) = 0; + virtual bool ShareBuzz(std::unique_ptr buzz, int64_t timestamp) = 0; + ... +}; +``` + +A `Buzz` object represents a snippet being posted. A class that implements the +`Buzzer` interface is capable of creating and sharing `Buzz`es. Methods in +`Buzzer` may return a `unique_ptr` or take a +`unique_ptr`. Now we need to mock `Buzzer` in our tests. + +To mock a method that accepts or returns move-only types, you just use the +familiar `MOCK_METHOD` syntax as usual: + +```cpp +class MockBuzzer : public Buzzer { + public: + MOCK_METHOD1(MakeBuzz, std::unique_ptr(StringPiece text)); + MOCK_METHOD2(ShareBuzz, bool(std::unique_ptr buzz, int64_t timestamp)); +}; +``` + +Now that we have the mock class defined, we can use it in tests. In the +following code examples, we assume that we have defined a `MockBuzzer` object +named `mock_buzzer_`: + +```cpp + MockBuzzer mock_buzzer_; +``` + +First let’s see how we can set expectations on the `MakeBuzz()` method, which +returns a `unique_ptr`. + +As usual, if you set an expectation without an action (i.e. the `.WillOnce()` or +`.WillRepeated()` clause), when that expectation fires, the default action for +that method will be taken. Since `unique_ptr<>` has a default constructor +that returns a null `unique_ptr`, that’s what you’ll get if you don’t specify an +action: + +```cpp + // Use the default action. + EXPECT_CALL(mock_buzzer_, MakeBuzz("hello")); + + // Triggers the previous EXPECT_CALL. + EXPECT_EQ(nullptr, mock_buzzer_.MakeBuzz("hello")); +``` + +If you are not happy with the default action, you can tweak it as usual; see +[Setting Default Actions](#setting-the-default-actions-for-a-mock-method). + +If you just need to return a pre-defined move-only value, you can use the +`Return(ByMove(...))` action: + +```cpp + // When this fires, the unique_ptr<> specified by ByMove(...) will + // be returned. + EXPECT_CALL(mock_buzzer_, MakeBuzz("world")) + .WillOnce(Return(ByMove(MakeUnique(AccessLevel::kInternal)))); + + EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("world")); +``` + +Note that `ByMove()` is essential here - if you drop it, the code won’t compile. + +Quiz time! What do you think will happen if a `Return(ByMove(...))` action is +performed more than once (e.g. you write +`.WillRepeatedly(Return(ByMove(...)));`)? Come think of it, after the first +time the action runs, the source value will be consumed (since it’s a move-only +value), so the next time around, there’s no value to move from -- you’ll get a +run-time error that `Return(ByMove(...))` can only be run once. + +If you need your mock method to do more than just moving a pre-defined value, +remember that you can always use a lambda or a callable object, which can do +pretty much anything you want: + +```cpp + EXPECT_CALL(mock_buzzer_, MakeBuzz("x")) + .WillRepeatedly([](StringPiece text) { + return MakeUnique(AccessLevel::kInternal); + }); + + EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x")); + EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x")); +``` + +Every time this `EXPECT_CALL` fires, a new `unique_ptr` will be +created and returned. You cannot do this with `Return(ByMove(...))`. + +That covers returning move-only values; but how do we work with methods +accepting move-only arguments? The answer is that they work normally, although +some actions will not compile when any of method's arguments are move-only. You +can always use `Return`, or a [lambda or functor](#using-functionsmethodsfunctors-as-actions): + +```cpp + using ::testing::Unused; + + EXPECT_CALL(mock_buzzer_, ShareBuzz(NotNull(), _)) .WillOnce(Return(true)); + EXPECT_TRUE(mock_buzzer_.ShareBuzz(MakeUnique(AccessLevel::kInternal)), + 0); + + EXPECT_CALL(mock_buzzer_, ShareBuzz(_, _)) .WillOnce( + [](std::unique_ptr buzz, Unused) { return buzz != nullptr; }); + EXPECT_FALSE(mock_buzzer_.ShareBuzz(nullptr, 0)); +``` + +Many built-in actions (`WithArgs`, `WithoutArgs`,`DeleteArg`, `SaveArg`, ...) +could in principle support move-only arguments, but the support for this is not +implemented yet. If this is blocking you, please file a bug. + +A few actions (e.g. `DoAll`) copy their arguments internally, so they can never +work with non-copyable objects; you'll have to use functors instead. + +##### Legacy workarounds for move-only types + +Support for move-only function arguments was only introduced to gMock in April +2017. In older code, you may encounter the following workaround for the lack of +this feature (it is no longer necessary - we're including it just for +reference): + +```cpp +class MockBuzzer : public Buzzer { + public: + MOCK_METHOD2(DoShareBuzz, bool(Buzz* buzz, Time timestamp)); + bool ShareBuzz(std::unique_ptr buzz, Time timestamp) override { + return DoShareBuzz(buzz.get(), timestamp); + } +}; +``` + +The trick is to delegate the `ShareBuzz()` method to a mock method (let’s call +it `DoShareBuzz()`) that does not take move-only parameters. Then, instead of +setting expectations on `ShareBuzz()`, you set them on the `DoShareBuzz()` mock +method: + +```cpp + MockBuzzer mock_buzzer_; + EXPECT_CALL(mock_buzzer_, DoShareBuzz(NotNull(), _)); + + // When one calls ShareBuzz() on the MockBuzzer like this, the call is + // forwarded to DoShareBuzz(), which is mocked. Therefore this statement + // will trigger the above EXPECT_CALL. + mock_buzzer_.ShareBuzz(MakeUnique(AccessLevel::kInternal), 0); +``` + + + +## Making the Compilation Faster ## + +Believe it or not, the _vast majority_ of the time spent on compiling +a mock class is in generating its constructor and destructor, as they +perform non-trivial tasks (e.g. verification of the +expectations). What's more, mock methods with different signatures +have different types and thus their constructors/destructors need to +be generated by the compiler separately. As a result, if you mock many +different types of methods, compiling your mock class can get really +slow. + +If you are experiencing slow compilation, you can move the definition +of your mock class' constructor and destructor out of the class body +and into a `.cpp` file. This way, even if you `#include` your mock +class in N files, the compiler only needs to generate its constructor +and destructor once, resulting in a much faster compilation. + +Let's illustrate the idea using an example. Here's the definition of a +mock class before applying this recipe: + +```cpp +// File mock_foo.h. +... +class MockFoo : public Foo { + public: + // Since we don't declare the constructor or the destructor, + // the compiler will generate them in every translation unit + // where this mock class is used. + + MOCK_METHOD0(DoThis, int()); + MOCK_METHOD1(DoThat, bool(const char* str)); + ... more mock methods ... +}; +``` + +After the change, it would look like: + +```cpp +// File mock_foo.h. +... +class MockFoo : public Foo { + public: + // The constructor and destructor are declared, but not defined, here. + MockFoo(); + virtual ~MockFoo(); + + MOCK_METHOD0(DoThis, int()); + MOCK_METHOD1(DoThat, bool(const char* str)); + ... more mock methods ... +}; +``` +and +```cpp +// File mock_foo.cpp. +#include "path/to/mock_foo.h" + +// The definitions may appear trivial, but the functions actually do a +// lot of things through the constructors/destructors of the member +// variables used to implement the mock methods. +MockFoo::MockFoo() {} +MockFoo::~MockFoo() {} +``` + +## Forcing a Verification ## + +When it's being destroyed, your friendly mock object will automatically +verify that all expectations on it have been satisfied, and will +generate [Google Test](../../googletest/) failures +if not. This is convenient as it leaves you with one less thing to +worry about. That is, unless you are not sure if your mock object will +be destroyed. + +How could it be that your mock object won't eventually be destroyed? +Well, it might be created on the heap and owned by the code you are +testing. Suppose there's a bug in that code and it doesn't delete the +mock object properly - you could end up with a passing test when +there's actually a bug. + +Using a heap checker is a good idea and can alleviate the concern, but +its implementation may not be 100% reliable. So, sometimes you do want +to _force_ Google Mock to verify a mock object before it is +(hopefully) destructed. You can do this with +`Mock::VerifyAndClearExpectations(&mock_object)`: + +```cpp +TEST(MyServerTest, ProcessesRequest) { + using ::testing::Mock; + + MockFoo* const foo = new MockFoo; + EXPECT_CALL(*foo, ...)...; + // ... other expectations ... + + // server now owns foo. + MyServer server(foo); + server.ProcessRequest(...); + + // In case that server's destructor will forget to delete foo, + // this will verify the expectations anyway. + Mock::VerifyAndClearExpectations(foo); +} // server is destroyed when it goes out of scope here. +``` + +**Tip:** The `Mock::VerifyAndClearExpectations()` function returns a +`bool` to indicate whether the verification was successful (`true` for +yes), so you can wrap that function call inside a `ASSERT_TRUE()` if +there is no point going further when the verification has failed. + +## Using Check Points ## + +Sometimes you may want to "reset" a mock object at various check +points in your test: at each check point, you verify that all existing +expectations on the mock object have been satisfied, and then you set +some new expectations on it as if it's newly created. This allows you +to work with a mock object in "phases" whose sizes are each +manageable. + +One such scenario is that in your test's `SetUp()` function, you may +want to put the object you are testing into a certain state, with the +help from a mock object. Once in the desired state, you want to clear +all expectations on the mock, such that in the `TEST_F` body you can +set fresh expectations on it. + +As you may have figured out, the `Mock::VerifyAndClearExpectations()` +function we saw in the previous recipe can help you here. Or, if you +are using `ON_CALL()` to set default actions on the mock object and +want to clear the default actions as well, use +`Mock::VerifyAndClear(&mock_object)` instead. This function does what +`Mock::VerifyAndClearExpectations(&mock_object)` does and returns the +same `bool`, **plus** it clears the `ON_CALL()` statements on +`mock_object` too. + +Another trick you can use to achieve the same effect is to put the +expectations in sequences and insert calls to a dummy "check-point" +function at specific places. Then you can verify that the mock +function calls do happen at the right time. For example, if you are +exercising code: + +```cpp +Foo(1); +Foo(2); +Foo(3); +``` + +and want to verify that `Foo(1)` and `Foo(3)` both invoke +`mock.Bar("a")`, but `Foo(2)` doesn't invoke anything. You can write: + +```cpp +using ::testing::MockFunction; + +TEST(FooTest, InvokesBarCorrectly) { + MyMock mock; + // Class MockFunction has exactly one mock method. It is named + // Call() and has type F. + MockFunction check; + { + InSequence s; + + EXPECT_CALL(mock, Bar("a")); + EXPECT_CALL(check, Call("1")); + EXPECT_CALL(check, Call("2")); + EXPECT_CALL(mock, Bar("a")); + } + Foo(1); + check.Call("1"); + Foo(2); + check.Call("2"); + Foo(3); +} +``` + +The expectation spec says that the first `Bar("a")` must happen before +check point "1", the second `Bar("a")` must happen after check point "2", +and nothing should happen between the two check points. The explicit +check points make it easy to tell which `Bar("a")` is called by which +call to `Foo()`. + +## Mocking Destructors ## + +Sometimes you want to make sure a mock object is destructed at the +right time, e.g. after `bar->A()` is called but before `bar->B()` is +called. We already know that you can specify constraints on the order +of mock function calls, so all we need to do is to mock the destructor +of the mock function. + +This sounds simple, except for one problem: a destructor is a special +function with special syntax and special semantics, and the +`MOCK_METHOD0` macro doesn't work for it: + +```cpp + MOCK_METHOD0(~MockFoo, void()); // Won't compile! +``` + +The good news is that you can use a simple pattern to achieve the same +effect. First, add a mock function `Die()` to your mock class and call +it in the destructor, like this: + +```cpp +class MockFoo : public Foo { + ... + // Add the following two lines to the mock class. + MOCK_METHOD0(Die, void()); + virtual ~MockFoo() { Die(); } +}; +``` + +(If the name `Die()` clashes with an existing symbol, choose another +name.) Now, we have translated the problem of testing when a `MockFoo` +object dies to testing when its `Die()` method is called: + +```cpp + MockFoo* foo = new MockFoo; + MockBar* bar = new MockBar; + ... + { + InSequence s; + + // Expects *foo to die after bar->A() and before bar->B(). + EXPECT_CALL(*bar, A()); + EXPECT_CALL(*foo, Die()); + EXPECT_CALL(*bar, B()); + } +``` + +And that's that. + +## Using Google Mock and Threads ## + +**IMPORTANT NOTE:** What we describe in this recipe is **ONLY** true on +platforms where Google Mock is thread-safe. Currently these are only +platforms that support the pthreads library (this includes Linux and Mac). +To make it thread-safe on other platforms we only need to implement +some synchronization operations in `"gtest/internal/gtest-port.h"`. + +In a **unit** test, it's best if you could isolate and test a piece of +code in a single-threaded context. That avoids race conditions and +dead locks, and makes debugging your test much easier. + +Yet many programs are multi-threaded, and sometimes to test something +we need to pound on it from more than one thread. Google Mock works +for this purpose too. + +Remember the steps for using a mock: + + 1. Create a mock object `foo`. + 1. Set its default actions and expectations using `ON_CALL()` and `EXPECT_CALL()`. + 1. The code under test calls methods of `foo`. + 1. Optionally, verify and reset the mock. + 1. Destroy the mock yourself, or let the code under test destroy it. The destructor will automatically verify it. + +If you follow the following simple rules, your mocks and threads can +live happily together: + + * Execute your _test code_ (as opposed to the code being tested) in _one_ thread. This makes your test easy to follow. + * Obviously, you can do step #1 without locking. + * When doing step #2 and #5, make sure no other thread is accessing `foo`. Obvious too, huh? + * #3 and #4 can be done either in one thread or in multiple threads - anyway you want. Google Mock takes care of the locking, so you don't have to do any - unless required by your test logic. + +If you violate the rules (for example, if you set expectations on a +mock while another thread is calling its methods), you get undefined +behavior. That's not fun, so don't do it. + +Google Mock guarantees that the action for a mock function is done in +the same thread that called the mock function. For example, in + +```cpp + EXPECT_CALL(mock, Foo(1)) + .WillOnce(action1); + EXPECT_CALL(mock, Foo(2)) + .WillOnce(action2); +``` + +if `Foo(1)` is called in thread 1 and `Foo(2)` is called in thread 2, +Google Mock will execute `action1` in thread 1 and `action2` in thread +2. + +Google Mock does _not_ impose a sequence on actions performed in +different threads (doing so may create deadlocks as the actions may +need to cooperate). This means that the execution of `action1` and +`action2` in the above example _may_ interleave. If this is a problem, +you should add proper synchronization logic to `action1` and `action2` +to make the test thread-safe. + + +Also, remember that `DefaultValue` is a global resource that +potentially affects _all_ living mock objects in your +program. Naturally, you won't want to mess with it from multiple +threads or when there still are mocks in action. + +## Controlling How Much Information Google Mock Prints ## + +When Google Mock sees something that has the potential of being an +error (e.g. a mock function with no expectation is called, a.k.a. an +uninteresting call, which is allowed but perhaps you forgot to +explicitly ban the call), it prints some warning messages, including +the arguments of the function and the return value. Hopefully this +will remind you to take a look and see if there is indeed a problem. + +Sometimes you are confident that your tests are correct and may not +appreciate such friendly messages. Some other times, you are debugging +your tests or learning about the behavior of the code you are testing, +and wish you could observe every mock call that happens (including +argument values and the return value). Clearly, one size doesn't fit +all. + +You can control how much Google Mock tells you using the +`--gmock_verbose=LEVEL` command-line flag, where `LEVEL` is a string +with three possible values: + + * `info`: Google Mock will print all informational messages, warnings, and errors (most verbose). At this setting, Google Mock will also log any calls to the `ON_CALL/EXPECT_CALL` macros. + * `warning`: Google Mock will print both warnings and errors (less verbose). This is the default. + * `error`: Google Mock will print errors only (least verbose). + +Alternatively, you can adjust the value of that flag from within your +tests like so: + +```cpp + ::testing::FLAGS_gmock_verbose = "error"; +``` + +Now, judiciously use the right flag to enable Google Mock serve you better! + +## Gaining Super Vision into Mock Calls ## + +You have a test using Google Mock. It fails: Google Mock tells you +that some expectations aren't satisfied. However, you aren't sure why: +Is there a typo somewhere in the matchers? Did you mess up the order +of the `EXPECT_CALL`s? Or is the code under test doing something +wrong? How can you find out the cause? + +Won't it be nice if you have X-ray vision and can actually see the +trace of all `EXPECT_CALL`s and mock method calls as they are made? +For each call, would you like to see its actual argument values and +which `EXPECT_CALL` Google Mock thinks it matches? + +You can unlock this power by running your test with the +`--gmock_verbose=info` flag. For example, given the test program: + +```cpp +using testing::_; +using testing::HasSubstr; +using testing::Return; + +class MockFoo { + public: + MOCK_METHOD2(F, void(const string& x, const string& y)); +}; + +TEST(Foo, Bar) { + MockFoo mock; + EXPECT_CALL(mock, F(_, _)).WillRepeatedly(Return()); + EXPECT_CALL(mock, F("a", "b")); + EXPECT_CALL(mock, F("c", HasSubstr("d"))); + + mock.F("a", "good"); + mock.F("a", "b"); +} +``` + +if you run it with `--gmock_verbose=info`, you will see this output: + +``` +[ RUN ] Foo.Bar + +foo_test.cc:14: EXPECT_CALL(mock, F(_, _)) invoked +foo_test.cc:15: EXPECT_CALL(mock, F("a", "b")) invoked +foo_test.cc:16: EXPECT_CALL(mock, F("c", HasSubstr("d"))) invoked +foo_test.cc:14: Mock function call matches EXPECT_CALL(mock, F(_, _))... + Function call: F(@0x7fff7c8dad40"a", @0x7fff7c8dad10"good") +foo_test.cc:15: Mock function call matches EXPECT_CALL(mock, F("a", "b"))... + Function call: F(@0x7fff7c8dada0"a", @0x7fff7c8dad70"b") +foo_test.cc:16: Failure +Actual function call count doesn't match EXPECT_CALL(mock, F("c", HasSubstr("d")))... + Expected: to be called once + Actual: never called - unsatisfied and active +[ FAILED ] Foo.Bar +``` + +Suppose the bug is that the `"c"` in the third `EXPECT_CALL` is a typo +and should actually be `"a"`. With the above message, you should see +that the actual `F("a", "good")` call is matched by the first +`EXPECT_CALL`, not the third as you thought. From that it should be +obvious that the third `EXPECT_CALL` is written wrong. Case solved. + +## Running Tests in Emacs ## + +If you build and run your tests in Emacs, the source file locations of +Google Mock and [Google Test](../../googletest/) +errors will be highlighted. Just press `` on one of them and +you'll be taken to the offending line. Or, you can just type `C-x `` +to jump to the next error. + +To make it even easier, you can add the following lines to your +`~/.emacs` file: + +``` +(global-set-key "\M-m" 'compile) ; m is for make +(global-set-key [M-down] 'next-error) +(global-set-key [M-up] '(lambda () (interactive) (next-error -1))) +``` + +Then you can type `M-m` to start a build, or `M-up`/`M-down` to move +back and forth between errors. + +## Fusing Google Mock Source Files ## + +Google Mock's implementation consists of dozens of files (excluding +its own tests). Sometimes you may want them to be packaged up in +fewer files instead, such that you can easily copy them to a new +machine and start hacking there. For this we provide an experimental +Python script `fuse_gmock_files.py` in the `scripts/` directory +(starting with release 1.2.0). Assuming you have Python 2.4 or above +installed on your machine, just go to that directory and run +``` +python fuse_gmock_files.py OUTPUT_DIR +``` + +and you should see an `OUTPUT_DIR` directory being created with files +`gtest/gtest.h`, `gmock/gmock.h`, and `gmock-gtest-all.cc` in it. +These three files contain everything you need to use Google Mock (and +Google Test). Just copy them to anywhere you want and you are ready +to write tests and use mocks. You can use the +[make/Makefile](../make/Makefile) file as an example on how to compile your tests +against them. + +# Extending Google Mock # + +## Writing New Matchers Quickly ## + +The `MATCHER*` family of macros can be used to define custom matchers +easily. The syntax: + +```cpp +MATCHER(name, description_string_expression) { statements; } +``` + +will define a matcher with the given name that executes the +statements, which must return a `bool` to indicate if the match +succeeds. Inside the statements, you can refer to the value being +matched by `arg`, and refer to its type by `arg_type`. + +The description string is a `string`-typed expression that documents +what the matcher does, and is used to generate the failure message +when the match fails. It can (and should) reference the special +`bool` variable `negation`, and should evaluate to the description of +the matcher when `negation` is `false`, or that of the matcher's +negation when `negation` is `true`. + +For convenience, we allow the description string to be empty (`""`), +in which case Google Mock will use the sequence of words in the +matcher name as the description. + +For example: +```cpp +MATCHER(IsDivisibleBy7, "") { return (arg % 7) == 0; } +``` +allows you to write +```cpp + // Expects mock_foo.Bar(n) to be called where n is divisible by 7. + EXPECT_CALL(mock_foo, Bar(IsDivisibleBy7())); +``` +or, +```cpp +using ::testing::Not; +... + EXPECT_THAT(some_expression, IsDivisibleBy7()); + EXPECT_THAT(some_other_expression, Not(IsDivisibleBy7())); +``` +If the above assertions fail, they will print something like: +``` + Value of: some_expression + Expected: is divisible by 7 + Actual: 27 +... + Value of: some_other_expression + Expected: not (is divisible by 7) + Actual: 21 +``` +where the descriptions `"is divisible by 7"` and `"not (is divisible +by 7)"` are automatically calculated from the matcher name +`IsDivisibleBy7`. + +As you may have noticed, the auto-generated descriptions (especially +those for the negation) may not be so great. You can always override +them with a string expression of your own: +```cpp +MATCHER(IsDivisibleBy7, std::string(negation ? "isn't" : "is") + + " divisible by 7") { + return (arg % 7) == 0; +} +``` + +Optionally, you can stream additional information to a hidden argument +named `result_listener` to explain the match result. For example, a +better definition of `IsDivisibleBy7` is: +```cpp +MATCHER(IsDivisibleBy7, "") { + if ((arg % 7) == 0) + return true; + + *result_listener << "the remainder is " << (arg % 7); + return false; +} +``` + +With this definition, the above assertion will give a better message: +``` + Value of: some_expression + Expected: is divisible by 7 + Actual: 27 (the remainder is 6) +``` + +You should let `MatchAndExplain()` print _any additional information_ +that can help a user understand the match result. Note that it should +explain why the match succeeds in case of a success (unless it's +obvious) - this is useful when the matcher is used inside +`Not()`. There is no need to print the argument value itself, as +Google Mock already prints it for you. + +**Notes:** + + 1. The type of the value being matched (`arg_type`) is determined by the context in which you use the matcher and is supplied to you by the compiler, so you don't need to worry about declaring it (nor can you). This allows the matcher to be polymorphic. For example, `IsDivisibleBy7()` can be used to match any type where the value of `(arg % 7) == 0` can be implicitly converted to a `bool`. In the `Bar(IsDivisibleBy7())` example above, if method `Bar()` takes an `int`, `arg_type` will be `int`; if it takes an `unsigned long`, `arg_type` will be `unsigned long`; and so on. + 1. Google Mock doesn't guarantee when or how many times a matcher will be invoked. Therefore the matcher logic must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters). This requirement must be satisfied no matter how you define the matcher (e.g. using one of the methods described in the following recipes). In particular, a matcher can never call a mock function, as that will affect the state of the mock object and Google Mock. + +## Writing New Parameterized Matchers Quickly ## + +Sometimes you'll want to define a matcher that has parameters. For that you +can use the macro: +```cpp +MATCHER_P(name, param_name, description_string) { statements; } +``` +where the description string can be either `""` or a string expression +that references `negation` and `param_name`. + +For example: +```cpp +MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; } +``` +will allow you to write: +```cpp + EXPECT_THAT(Blah("a"), HasAbsoluteValue(n)); +``` +which may lead to this message (assuming `n` is 10): +``` + Value of: Blah("a") + Expected: has absolute value 10 + Actual: -9 +``` + +Note that both the matcher description and its parameter are +printed, making the message human-friendly. + +In the matcher definition body, you can write `foo_type` to +reference the type of a parameter named `foo`. For example, in the +body of `MATCHER_P(HasAbsoluteValue, value)` above, you can write +`value_type` to refer to the type of `value`. + +Google Mock also provides `MATCHER_P2`, `MATCHER_P3`, ..., up to +`MATCHER_P10` to support multi-parameter matchers: +```cpp +MATCHER_Pk(name, param_1, ..., param_k, description_string) { statements; } +``` + +Please note that the custom description string is for a particular +**instance** of the matcher, where the parameters have been bound to +actual values. Therefore usually you'll want the parameter values to +be part of the description. Google Mock lets you do that by +referencing the matcher parameters in the description string +expression. + +For example, +```cpp + using ::testing::PrintToString; + MATCHER_P2(InClosedRange, low, hi, + std::string(negation ? "isn't" : "is") + " in range [" + + PrintToString(low) + ", " + PrintToString(hi) + "]") { + return low <= arg && arg <= hi; + } + ... + EXPECT_THAT(3, InClosedRange(4, 6)); +``` +would generate a failure that contains the message: +``` + Expected: is in range [4, 6] +``` + +If you specify `""` as the description, the failure message will +contain the sequence of words in the matcher name followed by the +parameter values printed as a tuple. For example, +```cpp + MATCHER_P2(InClosedRange, low, hi, "") { ... } + ... + EXPECT_THAT(3, InClosedRange(4, 6)); +``` +would generate a failure that contains the text: +``` + Expected: in closed range (4, 6) +``` + +For the purpose of typing, you can view +```cpp +MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... } +``` +as shorthand for +```cpp +template +FooMatcherPk +Foo(p1_type p1, ..., pk_type pk) { ... } +``` + +When you write `Foo(v1, ..., vk)`, the compiler infers the types of +the parameters `v1`, ..., and `vk` for you. If you are not happy with +the result of the type inference, you can specify the types by +explicitly instantiating the template, as in `Foo(5, false)`. +As said earlier, you don't get to (or need to) specify +`arg_type` as that's determined by the context in which the matcher +is used. + +You can assign the result of expression `Foo(p1, ..., pk)` to a +variable of type `FooMatcherPk`. This can be +useful when composing matchers. Matchers that don't have a parameter +or have only one parameter have special types: you can assign `Foo()` +to a `FooMatcher`-typed variable, and assign `Foo(p)` to a +`FooMatcherP`-typed variable. + +While you can instantiate a matcher template with reference types, +passing the parameters by pointer usually makes your code more +readable. If, however, you still want to pass a parameter by +reference, be aware that in the failure message generated by the +matcher you will see the value of the referenced object but not its +address. + +You can overload matchers with different numbers of parameters: +```cpp +MATCHER_P(Blah, a, description_string_1) { ... } +MATCHER_P2(Blah, a, b, description_string_2) { ... } +``` + +While it's tempting to always use the `MATCHER*` macros when defining +a new matcher, you should also consider implementing +`MatcherInterface` or using `MakePolymorphicMatcher()` instead (see +the recipes that follow), especially if you need to use the matcher a +lot. While these approaches require more work, they give you more +control on the types of the value being matched and the matcher +parameters, which in general leads to better compiler error messages +that pay off in the long run. They also allow overloading matchers +based on parameter types (as opposed to just based on the number of +parameters). + +## Writing New Monomorphic Matchers ## + +A matcher of argument type `T` implements +`::testing::MatcherInterface` and does two things: it tests whether a +value of type `T` matches the matcher, and can describe what kind of +values it matches. The latter ability is used for generating readable +error messages when expectations are violated. + +The interface looks like this: + +```cpp +class MatchResultListener { + public: + ... + // Streams x to the underlying ostream; does nothing if the ostream + // is NULL. + template + MatchResultListener& operator<<(const T& x); + + // Returns the underlying ostream. + ::std::ostream* stream(); +}; + +template +class MatcherInterface { + public: + virtual ~MatcherInterface(); + + // Returns true iff the matcher matches x; also explains the match + // result to 'listener'. + virtual bool MatchAndExplain(T x, MatchResultListener* listener) const = 0; + + // Describes this matcher to an ostream. + virtual void DescribeTo(::std::ostream* os) const = 0; + + // Describes the negation of this matcher to an ostream. + virtual void DescribeNegationTo(::std::ostream* os) const; +}; +``` + +If you need a custom matcher but `Truly()` is not a good option (for +example, you may not be happy with the way `Truly(predicate)` +describes itself, or you may want your matcher to be polymorphic as +`Eq(value)` is), you can define a matcher to do whatever you want in +two steps: first implement the matcher interface, and then define a +factory function to create a matcher instance. The second step is not +strictly needed but it makes the syntax of using the matcher nicer. + +For example, you can define a matcher to test whether an `int` is +divisible by 7 and then use it like this: +```cpp +using ::testing::MakeMatcher; +using ::testing::Matcher; +using ::testing::MatcherInterface; +using ::testing::MatchResultListener; + +class DivisibleBy7Matcher : public MatcherInterface { + public: + virtual bool MatchAndExplain(int n, MatchResultListener* listener) const { + return (n % 7) == 0; + } + + virtual void DescribeTo(::std::ostream* os) const { + *os << "is divisible by 7"; + } + + virtual void DescribeNegationTo(::std::ostream* os) const { + *os << "is not divisible by 7"; + } +}; + +inline Matcher DivisibleBy7() { + return MakeMatcher(new DivisibleBy7Matcher); +} +... + + EXPECT_CALL(foo, Bar(DivisibleBy7())); +``` + +You may improve the matcher message by streaming additional +information to the `listener` argument in `MatchAndExplain()`: + +```cpp +class DivisibleBy7Matcher : public MatcherInterface { + public: + virtual bool MatchAndExplain(int n, + MatchResultListener* listener) const { + const int remainder = n % 7; + if (remainder != 0) { + *listener << "the remainder is " << remainder; + } + return remainder == 0; + } + ... +}; +``` + +Then, `EXPECT_THAT(x, DivisibleBy7());` may general a message like this: +``` +Value of: x +Expected: is divisible by 7 + Actual: 23 (the remainder is 2) +``` + +## Writing New Polymorphic Matchers ## + +You've learned how to write your own matchers in the previous +recipe. Just one problem: a matcher created using `MakeMatcher()` only +works for one particular type of arguments. If you want a +_polymorphic_ matcher that works with arguments of several types (for +instance, `Eq(x)` can be used to match a `value` as long as `value` == +`x` compiles -- `value` and `x` don't have to share the same type), +you can learn the trick from `"gmock/gmock-matchers.h"` but it's a bit +involved. + +Fortunately, most of the time you can define a polymorphic matcher +easily with the help of `MakePolymorphicMatcher()`. Here's how you can +define `NotNull()` as an example: + +```cpp +using ::testing::MakePolymorphicMatcher; +using ::testing::MatchResultListener; +using ::testing::NotNull; +using ::testing::PolymorphicMatcher; + +class NotNullMatcher { + public: + // To implement a polymorphic matcher, first define a COPYABLE class + // that has three members MatchAndExplain(), DescribeTo(), and + // DescribeNegationTo(), like the following. + + // In this example, we want to use NotNull() with any pointer, so + // MatchAndExplain() accepts a pointer of any type as its first argument. + // In general, you can define MatchAndExplain() as an ordinary method or + // a method template, or even overload it. + template + bool MatchAndExplain(T* p, + MatchResultListener* /* listener */) const { + return p != NULL; + } + + // Describes the property of a value matching this matcher. + void DescribeTo(::std::ostream* os) const { *os << "is not NULL"; } + + // Describes the property of a value NOT matching this matcher. + void DescribeNegationTo(::std::ostream* os) const { *os << "is NULL"; } +}; + +// To construct a polymorphic matcher, pass an instance of the class +// to MakePolymorphicMatcher(). Note the return type. +inline PolymorphicMatcher NotNull() { + return MakePolymorphicMatcher(NotNullMatcher()); +} +... + + EXPECT_CALL(foo, Bar(NotNull())); // The argument must be a non-NULL pointer. +``` + +**Note:** Your polymorphic matcher class does **not** need to inherit from +`MatcherInterface` or any other class, and its methods do **not** need +to be virtual. + +Like in a monomorphic matcher, you may explain the match result by +streaming additional information to the `listener` argument in +`MatchAndExplain()`. + +## Writing New Cardinalities ## + +A cardinality is used in `Times()` to tell Google Mock how many times +you expect a call to occur. It doesn't have to be exact. For example, +you can say `AtLeast(5)` or `Between(2, 4)`. + +If the built-in set of cardinalities doesn't suit you, you are free to +define your own by implementing the following interface (in namespace +`testing`): + +```cpp +class CardinalityInterface { + public: + virtual ~CardinalityInterface(); + + // Returns true iff call_count calls will satisfy this cardinality. + virtual bool IsSatisfiedByCallCount(int call_count) const = 0; + + // Returns true iff call_count calls will saturate this cardinality. + virtual bool IsSaturatedByCallCount(int call_count) const = 0; + + // Describes self to an ostream. + virtual void DescribeTo(::std::ostream* os) const = 0; +}; +``` + +For example, to specify that a call must occur even number of times, +you can write + +```cpp +using ::testing::Cardinality; +using ::testing::CardinalityInterface; +using ::testing::MakeCardinality; + +class EvenNumberCardinality : public CardinalityInterface { + public: + virtual bool IsSatisfiedByCallCount(int call_count) const { + return (call_count % 2) == 0; + } + + virtual bool IsSaturatedByCallCount(int call_count) const { + return false; + } + + virtual void DescribeTo(::std::ostream* os) const { + *os << "called even number of times"; + } +}; + +Cardinality EvenNumber() { + return MakeCardinality(new EvenNumberCardinality); +} +... + + EXPECT_CALL(foo, Bar(3)) + .Times(EvenNumber()); +``` + +## Writing New Actions Quickly ## + +If the built-in actions don't work for you, and you find it +inconvenient to use `Invoke()`, you can use a macro from the `ACTION*` +family to quickly define a new action that can be used in your code as +if it's a built-in action. + +By writing +```cpp +ACTION(name) { statements; } +``` +in a namespace scope (i.e. not inside a class or function), you will +define an action with the given name that executes the statements. +The value returned by `statements` will be used as the return value of +the action. Inside the statements, you can refer to the K-th +(0-based) argument of the mock function as `argK`. For example: +```cpp +ACTION(IncrementArg1) { return ++(*arg1); } +``` +allows you to write +```cpp +... WillOnce(IncrementArg1()); +``` + +Note that you don't need to specify the types of the mock function +arguments. Rest assured that your code is type-safe though: +you'll get a compiler error if `*arg1` doesn't support the `++` +operator, or if the type of `++(*arg1)` isn't compatible with the mock +function's return type. + +Another example: +```cpp +ACTION(Foo) { + (*arg2)(5); + Blah(); + *arg1 = 0; + return arg0; +} +``` +defines an action `Foo()` that invokes argument #2 (a function pointer) +with 5, calls function `Blah()`, sets the value pointed to by argument +#1 to 0, and returns argument #0. + +For more convenience and flexibility, you can also use the following +pre-defined symbols in the body of `ACTION`: + +| `argK_type` | The type of the K-th (0-based) argument of the mock function | +|:----------------|:-------------------------------------------------------------| +| `args` | All arguments of the mock function as a tuple | +| `args_type` | The type of all arguments of the mock function as a tuple | +| `return_type` | The return type of the mock function | +| `function_type` | The type of the mock function | + +For example, when using an `ACTION` as a stub action for mock function: +```cpp +int DoSomething(bool flag, int* ptr); +``` +we have: + +| **Pre-defined Symbol** | **Is Bound To** | +|:-----------------------|:----------------| +| `arg0` | the value of `flag` | +| `arg0_type` | the type `bool` | +| `arg1` | the value of `ptr` | +| `arg1_type` | the type `int*` | +| `args` | the tuple `(flag, ptr)` | +| `args_type` | the type `::testing::tuple` | +| `return_type` | the type `int` | +| `function_type` | the type `int(bool, int*)` | + +## Writing New Parameterized Actions Quickly ## + +Sometimes you'll want to parameterize an action you define. For that +we have another macro +```cpp +ACTION_P(name, param) { statements; } +``` + +For example, +```cpp +ACTION_P(Add, n) { return arg0 + n; } +``` +will allow you to write +```cpp +// Returns argument #0 + 5. +... WillOnce(Add(5)); +``` + +For convenience, we use the term _arguments_ for the values used to +invoke the mock function, and the term _parameters_ for the values +used to instantiate an action. + +Note that you don't need to provide the type of the parameter either. +Suppose the parameter is named `param`, you can also use the +Google-Mock-defined symbol `param_type` to refer to the type of the +parameter as inferred by the compiler. For example, in the body of +`ACTION_P(Add, n)` above, you can write `n_type` for the type of `n`. + +Google Mock also provides `ACTION_P2`, `ACTION_P3`, and etc to support +multi-parameter actions. For example, +```cpp +ACTION_P2(ReturnDistanceTo, x, y) { + double dx = arg0 - x; + double dy = arg1 - y; + return sqrt(dx*dx + dy*dy); +} +``` +lets you write +```cpp +... WillOnce(ReturnDistanceTo(5.0, 26.5)); +``` + +You can view `ACTION` as a degenerated parameterized action where the +number of parameters is 0. + +You can also easily define actions overloaded on the number of parameters: +```cpp +ACTION_P(Plus, a) { ... } +ACTION_P2(Plus, a, b) { ... } +``` + +## Restricting the Type of an Argument or Parameter in an ACTION ## + +For maximum brevity and reusability, the `ACTION*` macros don't ask +you to provide the types of the mock function arguments and the action +parameters. Instead, we let the compiler infer the types for us. + +Sometimes, however, we may want to be more explicit about the types. +There are several tricks to do that. For example: +```cpp +ACTION(Foo) { + // Makes sure arg0 can be converted to int. + int n = arg0; + ... use n instead of arg0 here ... +} + +ACTION_P(Bar, param) { + // Makes sure the type of arg1 is const char*. + ::testing::StaticAssertTypeEq(); + + // Makes sure param can be converted to bool. + bool flag = param; +} +``` +where `StaticAssertTypeEq` is a compile-time assertion in Google Test +that verifies two types are the same. + +## Writing New Action Templates Quickly ## + +Sometimes you want to give an action explicit template parameters that +cannot be inferred from its value parameters. `ACTION_TEMPLATE()` +supports that and can be viewed as an extension to `ACTION()` and +`ACTION_P*()`. + +The syntax: +```cpp +ACTION_TEMPLATE(ActionName, + HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m), + AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; } +``` + +defines an action template that takes _m_ explicit template parameters +and _n_ value parameters, where _m_ is between 1 and 10, and _n_ is +between 0 and 10. `name_i` is the name of the i-th template +parameter, and `kind_i` specifies whether it's a `typename`, an +integral constant, or a template. `p_i` is the name of the i-th value +parameter. + +Example: +```cpp +// DuplicateArg(output) converts the k-th argument of the mock +// function to type T and copies it to *output. +ACTION_TEMPLATE(DuplicateArg, + // Note the comma between int and k: + HAS_2_TEMPLATE_PARAMS(int, k, typename, T), + AND_1_VALUE_PARAMS(output)) { + *output = T(::testing::get(args)); +} +``` + +To create an instance of an action template, write: +```cpp + ActionName(v1, ..., v_n) +``` +where the `t`s are the template arguments and the +`v`s are the value arguments. The value argument +types are inferred by the compiler. For example: +```cpp +using ::testing::_; +... + int n; + EXPECT_CALL(mock, Foo(_, _)) + .WillOnce(DuplicateArg<1, unsigned char>(&n)); +``` + +If you want to explicitly specify the value argument types, you can +provide additional template arguments: +```cpp + ActionName(v1, ..., v_n) +``` +where `u_i` is the desired type of `v_i`. + +`ACTION_TEMPLATE` and `ACTION`/`ACTION_P*` can be overloaded on the +number of value parameters, but not on the number of template +parameters. Without the restriction, the meaning of the following is +unclear: + +```cpp + OverloadedAction(x); +``` + +Are we using a single-template-parameter action where `bool` refers to +the type of `x`, or a two-template-parameter action where the compiler +is asked to infer the type of `x`? + +## Using the ACTION Object's Type ## + +If you are writing a function that returns an `ACTION` object, you'll +need to know its type. The type depends on the macro used to define +the action and the parameter types. The rule is relatively simple: + +| **Given Definition** | **Expression** | **Has Type** | +|:---------------------|:---------------|:-------------| +| `ACTION(Foo)` | `Foo()` | `FooAction` | +| `ACTION_TEMPLATE(Foo, HAS_m_TEMPLATE_PARAMS(...), AND_0_VALUE_PARAMS())` | `Foo()` | `FooAction` | +| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP` | +| `ACTION_TEMPLATE(Bar, HAS_m_TEMPLATE_PARAMS(...), AND_1_VALUE_PARAMS(p1))` | `Bar(int_value)` | `FooActionP` | +| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value, int_value)` | `BazActionP2` | +| `ACTION_TEMPLATE(Baz, HAS_m_TEMPLATE_PARAMS(...), AND_2_VALUE_PARAMS(p1, p2))`| `Baz(bool_value, int_value)` | `FooActionP2` | +| ... | ... | ... | + +Note that we have to pick different suffixes (`Action`, `ActionP`, +`ActionP2`, and etc) for actions with different numbers of value +parameters, or the action definitions cannot be overloaded on the +number of them. + +## Writing New Monomorphic Actions ## + +While the `ACTION*` macros are very convenient, sometimes they are +inappropriate. For example, despite the tricks shown in the previous +recipes, they don't let you directly specify the types of the mock +function arguments and the action parameters, which in general leads +to unoptimized compiler error messages that can baffle unfamiliar +users. They also don't allow overloading actions based on parameter +types without jumping through some hoops. + +An alternative to the `ACTION*` macros is to implement +`::testing::ActionInterface`, where `F` is the type of the mock +function in which the action will be used. For example: + +```cpp +template class ActionInterface { + public: + virtual ~ActionInterface(); + + // Performs the action. Result is the return type of function type + // F, and ArgumentTuple is the tuple of arguments of F. + // + // For example, if F is int(bool, const string&), then Result would + // be int, and ArgumentTuple would be ::testing::tuple. + virtual Result Perform(const ArgumentTuple& args) = 0; +}; + +using ::testing::_; +using ::testing::Action; +using ::testing::ActionInterface; +using ::testing::MakeAction; + +typedef int IncrementMethod(int*); + +class IncrementArgumentAction : public ActionInterface { + public: + virtual int Perform(const ::testing::tuple& args) { + int* p = ::testing::get<0>(args); // Grabs the first argument. + return *p++; + } +}; + +Action IncrementArgument() { + return MakeAction(new IncrementArgumentAction); +} +... + + EXPECT_CALL(foo, Baz(_)) + .WillOnce(IncrementArgument()); + + int n = 5; + foo.Baz(&n); // Should return 5 and change n to 6. +``` + +## Writing New Polymorphic Actions ## + +The previous recipe showed you how to define your own action. This is +all good, except that you need to know the type of the function in +which the action will be used. Sometimes that can be a problem. For +example, if you want to use the action in functions with _different_ +types (e.g. like `Return()` and `SetArgPointee()`). + +If an action can be used in several types of mock functions, we say +it's _polymorphic_. The `MakePolymorphicAction()` function template +makes it easy to define such an action: + +```cpp +namespace testing { + +template +PolymorphicAction MakePolymorphicAction(const Impl& impl); + +} // namespace testing +``` + +As an example, let's define an action that returns the second argument +in the mock function's argument list. The first step is to define an +implementation class: + +```cpp +class ReturnSecondArgumentAction { + public: + template + Result Perform(const ArgumentTuple& args) const { + // To get the i-th (0-based) argument, use ::testing::get(args). + return ::testing::get<1>(args); + } +}; +``` + +This implementation class does _not_ need to inherit from any +particular class. What matters is that it must have a `Perform()` +method template. This method template takes the mock function's +arguments as a tuple in a **single** argument, and returns the result of +the action. It can be either `const` or not, but must be invokable +with exactly one template argument, which is the result type. In other +words, you must be able to call `Perform(args)` where `R` is the +mock function's return type and `args` is its arguments in a tuple. + +Next, we use `MakePolymorphicAction()` to turn an instance of the +implementation class into the polymorphic action we need. It will be +convenient to have a wrapper for this: + +```cpp +using ::testing::MakePolymorphicAction; +using ::testing::PolymorphicAction; + +PolymorphicAction ReturnSecondArgument() { + return MakePolymorphicAction(ReturnSecondArgumentAction()); +} +``` + +Now, you can use this polymorphic action the same way you use the +built-in ones: + +```cpp +using ::testing::_; + +class MockFoo : public Foo { + public: + MOCK_METHOD2(DoThis, int(bool flag, int n)); + MOCK_METHOD3(DoThat, string(int x, const char* str1, const char* str2)); +}; +... + + MockFoo foo; + EXPECT_CALL(foo, DoThis(_, _)) + .WillOnce(ReturnSecondArgument()); + EXPECT_CALL(foo, DoThat(_, _, _)) + .WillOnce(ReturnSecondArgument()); + ... + foo.DoThis(true, 5); // Will return 5. + foo.DoThat(1, "Hi", "Bye"); // Will return "Hi". +``` + +## Teaching Google Mock How to Print Your Values ## + +When an uninteresting or unexpected call occurs, Google Mock prints the +argument values and the stack trace to help you debug. Assertion +macros like `EXPECT_THAT` and `EXPECT_EQ` also print the values in +question when the assertion fails. Google Mock and Google Test do this using +Google Test's user-extensible value printer. + +This printer knows how to print built-in C++ types, native arrays, STL +containers, and any type that supports the `<<` operator. For other +types, it prints the raw bytes in the value and hopes that you the +user can figure it out. +[Google Test's advanced guide](../../googletest/docs/advanced.md#teaching-googletest-how-to-print-your-values) +explains how to extend the printer to do a better job at +printing your particular type than to dump the bytes. diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/DesignDoc.md b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/DesignDoc.md new file mode 100644 index 000000000000..4cddc9d0a38a --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/DesignDoc.md @@ -0,0 +1,282 @@ +This page discusses the design of new Google Mock features. + + + +# Macros for Defining Actions # + +## Problem ## + +Due to the lack of closures in C++, it currently requires some +non-trivial effort to define a custom action in Google Mock.

While the other approaches require more work, they give +you more control on the types of the mock function arguments and the +action parameters, which in general leads to better compiler error +messages that pay off in the long run. They also allow overloading +actions based on parameter types, as opposed to just the number of +parameters. + +## Related Work ## + +As you may have realized, the `ACTION*` macros resemble closures (also +known as lambda expressions or anonymous functions). Indeed, both of +them seek to lower the syntactic overhead for defining a function. + +C++0x will support lambdas, but they are not part of C++ right now. +Some non-standard libraries (most notably BLL or Boost Lambda Library) +try to alleviate this problem. However, they are not a good choice +for defining actions as: + + * They are non-standard and not widely installed. Google Mock only depends on standard libraries and `tr1::tuple`, which is part of the new C++ standard and comes with gcc 4+. We want to keep it that way. + * They are not trivial to learn. + * They will become obsolete when C++0x's lambda feature is widely supported. We don't want to make our users use a dying library. + * Since they are based on operators, they are rather ad hoc: you cannot use statements, and you cannot pass the lambda arguments to a function, for example. + * They have subtle semantics that easily confuses new users. For example, in expression `_1++ + foo++`, `foo` will be incremented only once where the expression is evaluated, while `_1` will be incremented every time the unnamed function is invoked. This is far from intuitive. + +`ACTION*` avoid all these problems. + +## Future Improvements ## + +There may be a need for composing `ACTION*` definitions (i.e. invoking +another `ACTION` inside the definition of one `ACTION*`). We are not +sure we want it yet, as one can get a similar effect by putting +`ACTION` definitions in function templates and composing the function +templates. We'll revisit this based on user feedback. + +The reason we don't allow `ACTION*()` inside a function body is that +the current C++ standard doesn't allow function-local types to be used +to instantiate templates. The upcoming C++0x standard will lift this +restriction. Once this feature is widely supported by compilers, we +can revisit the implementation and add support for using `ACTION*()` +inside a function. + +C++0x will also support lambda expressions. When they become +available, we may want to support using lambdas as actions. + +# Macros for Defining Matchers # + +Once the macros for defining actions are implemented, we plan to do +the same for matchers: + +```cpp +MATCHER(name) { statements; } +``` + +where you can refer to the value being matched as `arg`.

The difference between fakes and mocks will become much clearer once you start to use mocks. + +**Google C++ Mocking Framework** (or **Google Mock** for short) is a library (sometimes we also call it a "framework" to make it sound cool) for creating mock classes and using them. It does to C++ what [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/) do to Java. + +Using Google Mock involves three basic steps: + + 1. Use some simple macros to describe the interface you want to mock, and they will expand to the implementation of your mock class; + 1. Create some mock objects and specify its expectations and behavior using an intuitive syntax; + 1. Exercise code that uses the mock objects. Google Mock will catch any violation of the expectations as soon as it arises. + +# Why Google Mock? # +While mock objects help you remove unnecessary dependencies in tests and make them fast and reliable, using mocks manually in C++ is _hard_: + + * Someone has to implement the mocks. The job is usually tedious and error-prone. No wonder people go great distances to avoid it. + * The quality of those manually written mocks is a bit, uh, unpredictable. You may see some really polished ones, but you may also see some that were hacked up in a hurry and have all sorts of ad-hoc restrictions. + * The knowledge you gained from using one mock doesn't transfer to the next. + +In contrast, Java and Python programmers have some fine mock frameworks, which automate the creation of mocks. As a result, mocking is a proven effective technique and widely adopted practice in those communities. Having the right tool absolutely makes the difference. + +Google Mock was built to help C++ programmers. It was inspired by [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/), but designed with C++'s specifics in mind. It is your friend if any of the following problems is bothering you: + + * You are stuck with a sub-optimal design and wish you had done more prototyping before it was too late, but prototyping in C++ is by no means "rapid". + * Your tests are slow as they depend on too many libraries or use expensive resources (e.g. a database). + * Your tests are brittle as some resources they use are unreliable (e.g. the network). + * You want to test how your code handles a failure (e.g. a file checksum error), but it's not easy to cause one. + * You need to make sure that your module interacts with other modules in the right way, but it's hard to observe the interaction; therefore you resort to observing the side effects at the end of the action, which is awkward at best. + * You want to "mock out" your dependencies, except that they don't have mock implementations yet; and, frankly, you aren't thrilled by some of those hand-written mocks. + +We encourage you to use Google Mock as: + + * a _design_ tool, for it lets you experiment with your interface design early and often. More iterations lead to better designs! + * a _testing_ tool to cut your tests' outbound dependencies and probe the interaction between your module and its collaborators. + +# Getting Started # +Using Google Mock is easy! Inside your C++ source file, just `#include` `"gtest/gtest.h"` and `"gmock/gmock.h"`, and you are ready to go. + +# A Case for Mock Turtles # +Let's look at an example. Suppose you are developing a graphics program that relies on a LOGO-like API for drawing. How would you test that it does the right thing? Well, you can run it and compare the screen with a golden screen snapshot, but let's admit it: tests like this are expensive to run and fragile (What if you just upgraded to a shiny new graphics card that has better anti-aliasing? Suddenly you have to update all your golden images.). It would be too painful if all your tests are like this. Fortunately, you learned about Dependency Injection and know the right thing to do: instead of having your application talk to the drawing API directly, wrap the API in an interface (say, `Turtle`) and code to that interface: + +```cpp +class Turtle { + ... + virtual ~Turtle() {} + virtual void PenUp() = 0; + virtual void PenDown() = 0; + virtual void Forward(int distance) = 0; + virtual void Turn(int degrees) = 0; + virtual void GoTo(int x, int y) = 0; + virtual int GetX() const = 0; + virtual int GetY() const = 0; +}; +``` + +(Note that the destructor of `Turtle` **must** be virtual, as is the case for **all** classes you intend to inherit from - otherwise the destructor of the derived class will not be called when you delete an object through a base pointer, and you'll get corrupted program states like memory leaks.) + +You can control whether the turtle's movement will leave a trace using `PenUp()` and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and `GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the turtle. + +Your program will normally use a real implementation of this interface. In tests, you can use a mock implementation instead. This allows you to easily check what drawing primitives your program is calling, with what arguments, and in which order. Tests written this way are much more robust (they won't break because your new machine does anti-aliasing differently), easier to read and maintain (the intent of a test is expressed in the code, not in some binary images), and run _much, much faster_. + +# Writing the Mock Class # +If you are lucky, the mocks you need to use have already been implemented by some nice people. If, however, you find yourself in the position to write a mock class, relax - Google Mock turns this task into a fun game! (Well, almost.) + +## How to Define It ## +Using the `Turtle` interface as example, here are the simple steps you need to follow: + + 1. Derive a class `MockTurtle` from `Turtle`. + 1. Take a _virtual_ function of `Turtle` (while it's possible to [mock non-virtual methods using templates](CookBook.md#mocking-nonvirtual-methods), it's much more involved). Count how many arguments it has. + 1. In the `public:` section of the child class, write `MOCK_METHODn();` (or `MOCK_CONST_METHODn();` if you are mocking a `const` method), where `n` is the number of the arguments; if you counted wrong, shame on you, and a compiler error will tell you so. + 1. Now comes the fun part: you take the function signature, cut-and-paste the _function name_ as the _first_ argument to the macro, and leave what's left as the _second_ argument (in case you're curious, this is the _type of the function_). + 1. Repeat until all virtual functions you want to mock are done. + +After the process, you should have something like: + +```cpp +#include "gmock/gmock.h" // Brings in Google Mock. +class MockTurtle : public Turtle { + public: + ... + MOCK_METHOD0(PenUp, void()); + MOCK_METHOD0(PenDown, void()); + MOCK_METHOD1(Forward, void(int distance)); + MOCK_METHOD1(Turn, void(int degrees)); + MOCK_METHOD2(GoTo, void(int x, int y)); + MOCK_CONST_METHOD0(GetX, int()); + MOCK_CONST_METHOD0(GetY, int()); +}; +``` + +You don't need to define these mock methods somewhere else - the `MOCK_METHOD*` macros will generate the definitions for you. It's that simple! Once you get the hang of it, you can pump out mock classes faster than your source-control system can handle your check-ins. + +**Tip:** If even this is too much work for you, you'll find the +`gmock_gen.py` tool in Google Mock's `scripts/generator/` directory (courtesy of the [cppclean](http://code.google.com/p/cppclean/) project) useful. This command-line +tool requires that you have Python 2.4 installed. You give it a C++ file and the name of an abstract class defined in it, +and it will print the definition of the mock class for you. Due to the +complexity of the C++ language, this script may not always work, but +it can be quite handy when it does. For more details, read the [user documentation](../scripts/generator/README). + +## Where to Put It ## +When you define a mock class, you need to decide where to put its definition. Some people put it in a `*_test.cc`. This is fine when the interface being mocked (say, `Foo`) is owned by the same person or team. Otherwise, when the owner of `Foo` changes it, your test could break. (You can't really expect `Foo`'s maintainer to fix every test that uses `Foo`, can you?) + +So, the rule of thumb is: if you need to mock `Foo` and it's owned by others, define the mock class in `Foo`'s package (better, in a `testing` sub-package such that you can clearly separate production code and testing utilities), and put it in a `mock_foo.h`. Then everyone can reference `mock_foo.h` from their tests. If `Foo` ever changes, there is only one copy of `MockFoo` to change, and only tests that depend on the changed methods need to be fixed. + +Another way to do it: you can introduce a thin layer `FooAdaptor` on top of `Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb changes in `Foo` much more easily. While this is more work initially, carefully choosing the adaptor interface can make your code easier to write and more readable (a net win in the long run), as you can choose `FooAdaptor` to fit your specific domain much better than `Foo` does. + +# Using Mocks in Tests # +Once you have a mock class, using it is easy. The typical work flow is: + + 1. Import the Google Mock names from the `testing` namespace such that you can use them unqualified (You only have to do it once per file. Remember that namespaces are a good idea and good for your health.). + 1. Create some mock objects. + 1. Specify your expectations on them (How many times will a method be called? With what arguments? What should it do? etc.). + 1. Exercise some code that uses the mocks; optionally, check the result using Google Test assertions. If a mock method is called more than expected or with wrong arguments, you'll get an error immediately. + 1. When a mock is destructed, Google Mock will automatically check whether all expectations on it have been satisfied. + +Here's an example: + +```cpp +#include "path/to/mock-turtle.h" +#include "gmock/gmock.h" +#include "gtest/gtest.h" +using ::testing::AtLeast; // #1 + +TEST(PainterTest, CanDrawSomething) { + MockTurtle turtle; // #2 + EXPECT_CALL(turtle, PenDown()) // #3 + .Times(AtLeast(1)); + + Painter painter(&turtle); // #4 + + EXPECT_TRUE(painter.DrawCircle(0, 0, 10)); +} // #5 + +int main(int argc, char** argv) { + // The following line must be executed to initialize Google Mock + // (and Google Test) before running the tests. + ::testing::InitGoogleMock(&argc, argv); + return RUN_ALL_TESTS(); +} +``` + +As you might have guessed, this test checks that `PenDown()` is called at least once. If the `painter` object didn't call this method, your test will fail with a message like this: + +``` +path/to/my_test.cc:119: Failure +Actual function call count doesn't match this expectation: +Actually: never called; +Expected: called at least once. +``` + +**Tip 1:** If you run the test from an Emacs buffer, you can hit `` on the line number displayed in the error message to jump right to the failed expectation. + +**Tip 2:** If your mock objects are never deleted, the final verification won't happen. Therefore it's a good idea to use a heap leak checker in your tests when you allocate mocks on the heap. + +**Important note:** Google Mock requires expectations to be set **before** the mock functions are called, otherwise the behavior is **undefined**. In particular, you mustn't interleave `EXPECT_CALL()`s and calls to the mock functions. + +This means `EXPECT_CALL()` should be read as expecting that a call will occur _in the future_, not that a call has occurred. Why does Google Mock work like that? Well, specifying the expectation beforehand allows Google Mock to report a violation as soon as it arises, when the context (stack trace, etc) is still available. This makes debugging much easier. + +Admittedly, this test is contrived and doesn't do much. You can easily achieve the same effect without using Google Mock. However, as we shall reveal soon, Google Mock allows you to do _much more_ with the mocks. + +## Using Google Mock with Any Testing Framework ## +If you want to use something other than Google Test (e.g. [CppUnit](http://sourceforge.net/projects/cppunit/) or +[CxxTest](https://cxxtest.com/)) as your testing framework, just change the `main()` function in the previous section to: +```cpp +int main(int argc, char** argv) { + // The following line causes Google Mock to throw an exception on failure, + // which will be interpreted by your testing framework as a test failure. + ::testing::GTEST_FLAG(throw_on_failure) = true; + ::testing::InitGoogleMock(&argc, argv); + ... whatever your testing framework requires ... +} +``` + +This approach has a catch: it makes Google Mock throw an exception +from a mock object's destructor sometimes. With some compilers, this +sometimes causes the test program to crash. You'll still be able to +notice that the test has failed, but it's not a graceful failure. + +A better solution is to use Google Test's +[event listener API](../../googletest/docs/advanced.md#extending-googletest-by-handling-test-events) +to report a test failure to your testing framework properly. You'll need to +implement the `OnTestPartResult()` method of the event listener interface, but it +should be straightforward. + +If this turns out to be too much work, we suggest that you stick with +Google Test, which works with Google Mock seamlessly (in fact, it is +technically part of Google Mock.). If there is a reason that you +cannot use Google Test, please let us know. + +# Setting Expectations # +The key to using a mock object successfully is to set the _right expectations_ on it. If you set the expectations too strict, your test will fail as the result of unrelated changes. If you set them too loose, bugs can slip through. You want to do it just right such that your test can catch exactly the kind of bugs you intend it to catch. Google Mock provides the necessary means for you to do it "just right." + +## General Syntax ## +In Google Mock we use the `EXPECT_CALL()` macro to set an expectation on a mock method. The general syntax is: + +```cpp +EXPECT_CALL(mock_object, method(matchers)) + .Times(cardinality) + .WillOnce(action) + .WillRepeatedly(action); +``` + +The macro has two arguments: first the mock object, and then the method and its arguments. Note that the two are separated by a comma (`,`), not a period (`.`). (Why using a comma? The answer is that it was necessary for technical reasons.) + +The macro can be followed by some optional _clauses_ that provide more information about the expectation. We'll discuss how each clause works in the coming sections. + +This syntax is designed to make an expectation read like English. For example, you can probably guess that + +```cpp +using ::testing::Return; +... +EXPECT_CALL(turtle, GetX()) + .Times(5) + .WillOnce(Return(100)) + .WillOnce(Return(150)) + .WillRepeatedly(Return(200)); +``` + +says that the `turtle` object's `GetX()` method will be called five times, it will return 100 the first time, 150 the second time, and then 200 every time. Some people like to call this style of syntax a Domain-Specific Language (DSL). + +**Note:** Why do we use a macro to do this? It serves two purposes: first it makes expectations easily identifiable (either by `grep` or by a human reader), and second it allows Google Mock to include the source file location of a failed expectation in messages, making debugging easier. + +## Matchers: What Arguments Do We Expect? ## +When a mock function takes arguments, we must specify what arguments we are expecting; for example: + +```cpp +// Expects the turtle to move forward by 100 units. +EXPECT_CALL(turtle, Forward(100)); +``` + +Sometimes you may not want to be too specific (Remember that talk about tests being too rigid? Over specification leads to brittle tests and obscures the intent of tests. Therefore we encourage you to specify only what's necessary - no more, no less.). If you care to check that `Forward()` will be called but aren't interested in its actual argument, write `_` as the argument, which means "anything goes": + +```cpp +using ::testing::_; +... +// Expects the turtle to move forward. +EXPECT_CALL(turtle, Forward(_)); +``` + +`_` is an instance of what we call **matchers**. A matcher is like a predicate and can test whether an argument is what we'd expect. You can use a matcher inside `EXPECT_CALL()` wherever a function argument is expected. + +A list of built-in matchers can be found in the [CheatSheet](CheatSheet.md). For example, here's the `Ge` (greater than or equal) matcher: + +```cpp +using ::testing::Ge; +... +EXPECT_CALL(turtle, Forward(Ge(100))); +``` + +This checks that the turtle will be told to go forward by at least 100 units. + +## Cardinalities: How Many Times Will It Be Called? ## +The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We call its argument a **cardinality** as it tells _how many times_ the call should occur. It allows us to repeat an expectation many times without actually writing it as many times. More importantly, a cardinality can be "fuzzy", just like a matcher can be. This allows a user to express the intent of a test exactly. + +An interesting special case is when we say `Times(0)`. You may have guessed - it means that the function shouldn't be called with the given arguments at all, and Google Mock will report a Google Test failure whenever the function is (wrongfully) called. + +We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the list of built-in cardinalities you can use, see the [CheatSheet](CheatSheet.md). + +The `Times()` clause can be omitted. **If you omit `Times()`, Google Mock will infer the cardinality for you.** The rules are easy to remember: + + * If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the `EXPECT_CALL()`, the inferred cardinality is `Times(1)`. + * If there are `n WillOnce()`'s but **no** `WillRepeatedly()`, where `n` >= 1, the cardinality is `Times(n)`. + * If there are `n WillOnce()`'s and **one** `WillRepeatedly()`, where `n` >= 0, the cardinality is `Times(AtLeast(n))`. + +**Quick quiz:** what do you think will happen if a function is expected to be called twice but actually called four times? + +## Actions: What Should It Do? ## +Remember that a mock object doesn't really have a working implementation? We as users have to tell it what to do when a method is invoked. This is easy in Google Mock. + +First, if the return type of a mock function is a built-in type or a pointer, the function has a **default action** (a `void` function will just return, a `bool` function will return `false`, and other functions will return 0). In addition, in C++ 11 and above, a mock function whose return type is default-constructible (i.e. has a default constructor) has a default action of returning a default-constructed value. If you don't say anything, this behavior will be used. + +Second, if a mock function doesn't have a default action, or the default action doesn't suit you, you can specify the action to be taken each time the expectation matches using a series of `WillOnce()` clauses followed by an optional `WillRepeatedly()`. For example, + +```cpp +using ::testing::Return; +... +EXPECT_CALL(turtle, GetX()) + .WillOnce(Return(100)) + .WillOnce(Return(200)) + .WillOnce(Return(300)); +``` + +This says that `turtle.GetX()` will be called _exactly three times_ (Google Mock inferred this from how many `WillOnce()` clauses we've written, since we didn't explicitly write `Times()`), and will return 100, 200, and 300 respectively. + +```cpp +using ::testing::Return; +... +EXPECT_CALL(turtle, GetY()) + .WillOnce(Return(100)) + .WillOnce(Return(200)) + .WillRepeatedly(Return(300)); +``` + +says that `turtle.GetY()` will be called _at least twice_ (Google Mock knows this as we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no explicit `Times()`), will return 100 the first time, 200 the second time, and 300 from the third time on. + +Of course, if you explicitly write a `Times()`, Google Mock will not try to infer the cardinality itself. What if the number you specified is larger than there are `WillOnce()` clauses? Well, after all `WillOnce()`s are used up, Google Mock will do the _default_ action for the function every time (unless, of course, you have a `WillRepeatedly()`.). + +What can we do inside `WillOnce()` besides `Return()`? You can return a reference using `ReturnRef(variable)`, or invoke a pre-defined function, among [others](CheatSheet.md#actions). + +**Important note:** The `EXPECT_CALL()` statement evaluates the action clause only once, even though the action may be performed many times. Therefore you must be careful about side effects. The following may not do what you want: + +```cpp +int n = 100; +EXPECT_CALL(turtle, GetX()) +.Times(4) +.WillRepeatedly(Return(n++)); +``` + +Instead of returning 100, 101, 102, ..., consecutively, this mock function will always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)` will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will return the same pointer every time. If you want the side effect to happen every time, you need to define a custom action, which we'll teach in the [CookBook](CookBook.md). + +Time for another quiz! What do you think the following means? + +```cpp +using ::testing::Return; +... +EXPECT_CALL(turtle, GetY()) +.Times(4) +.WillOnce(Return(100)); +``` + +Obviously `turtle.GetY()` is expected to be called four times. But if you think it will return 100 every time, think twice! Remember that one `WillOnce()` clause will be consumed each time the function is invoked and the default action will be taken afterwards. So the right answer is that `turtle.GetY()` will return 100 the first time, but **return 0 from the second time on**, as returning 0 is the default action for `int` functions. + +## Using Multiple Expectations ## +So far we've only shown examples where you have a single expectation. More realistically, you're going to specify expectations on multiple mock methods, which may be from multiple mock objects. + +By default, when a mock method is invoked, Google Mock will search the expectations in the **reverse order** they are defined, and stop when an active expectation that matches the arguments is found (you can think of it as "newer rules override older ones."). If the matching expectation cannot take any more calls, you will get an upper-bound-violated failure. Here's an example: + +```cpp +using ::testing::_; +... +EXPECT_CALL(turtle, Forward(_)); // #1 +EXPECT_CALL(turtle, Forward(10)) // #2 + .Times(2); +``` + +If `Forward(10)` is called three times in a row, the third time it will be an error, as the last matching expectation (#2) has been saturated. If, however, the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK, as now #1 will be the matching expectation. + +**Side note:** Why does Google Mock search for a match in the _reverse_ order of the expectations? The reason is that this allows a user to set up the default expectations in a mock object's constructor or the test fixture's set-up phase and then customize the mock by writing more specific expectations in the test body. So, if you have two expectations on the same method, you want to put the one with more specific matchers **after** the other, or the more specific rule would be shadowed by the more general one that comes after it. + +## Ordered vs Unordered Calls ## +By default, an expectation can match a call even though an earlier expectation hasn't been satisfied. In other words, the calls don't have to occur in the order the expectations are specified. + +Sometimes, you may want all the expected calls to occur in a strict order. To say this in Google Mock is easy: + +```cpp +using ::testing::InSequence; +... +TEST(FooTest, DrawsLineSegment) { + ... + { + InSequence dummy; + + EXPECT_CALL(turtle, PenDown()); + EXPECT_CALL(turtle, Forward(100)); + EXPECT_CALL(turtle, PenUp()); + } + Foo(); +} +``` + +By creating an object of type `InSequence`, all expectations in its scope are put into a _sequence_ and have to occur _sequentially_. Since we are just relying on the constructor and destructor of this object to do the actual work, its name is really irrelevant. + +In this example, we test that `Foo()` calls the three expected functions in the order as written. If a call is made out-of-order, it will be an error. + +(What if you care about the relative order of some of the calls, but not all of them? Can you specify an arbitrary partial order? The answer is ... yes! If you are impatient, the details can be found in the [CookBook](CookBook.md#expecting-partially-ordered-calls).) + +## All Expectations Are Sticky (Unless Said Otherwise) ## +Now let's do a quick quiz to see how well you can use this mock stuff already. How would you test that the turtle is asked to go to the origin _exactly twice_ (you want to ignore any other instructions it receives)? + +After you've come up with your answer, take a look at ours and compare notes (solve it yourself first - don't cheat!): + +```cpp +using ::testing::_; +... +EXPECT_CALL(turtle, GoTo(_, _)) // #1 + .Times(AnyNumber()); +EXPECT_CALL(turtle, GoTo(0, 0)) // #2 + .Times(2); +``` + +Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, Google Mock will see that the arguments match expectation #2 (remember that we always pick the last matching expectation). Now, since we said that there should be only two such calls, Google Mock will report an error immediately. This is basically what we've told you in the "Using Multiple Expectations" section above. + +This example shows that **expectations in Google Mock are "sticky" by default**, in the sense that they remain active even after we have reached their invocation upper bounds. This is an important rule to remember, as it affects the meaning of the spec, and is **different** to how it's done in many other mocking frameworks (Why'd we do that? Because we think our rule makes the common cases easier to express and understand.). + +Simple? Let's see if you've really understood it: what does the following code say? + +```cpp +using ::testing::Return; +... +for (int i = n; i > 0; i--) { + EXPECT_CALL(turtle, GetX()) + .WillOnce(Return(10*i)); +} +``` + +If you think it says that `turtle.GetX()` will be called `n` times and will return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we said, expectations are sticky. So, the second time `turtle.GetX()` is called, the last (latest) `EXPECT_CALL()` statement will match, and will immediately lead to an "upper bound exceeded" error - this piece of code is not very useful! + +One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is to explicitly say that the expectations are _not_ sticky. In other words, they should _retire_ as soon as they are saturated: + +```cpp +using ::testing::Return; +... +for (int i = n; i > 0; i--) { + EXPECT_CALL(turtle, GetX()) + .WillOnce(Return(10*i)) + .RetiresOnSaturation(); +} +``` + +And, there's a better way to do it: in this case, we expect the calls to occur in a specific order, and we line up the actions to match the order. Since the order is important here, we should make it explicit using a sequence: + +```cpp +using ::testing::InSequence; +using ::testing::Return; +... +{ + InSequence s; + + for (int i = 1; i <= n; i++) { + EXPECT_CALL(turtle, GetX()) + .WillOnce(Return(10*i)) + .RetiresOnSaturation(); + } +} +``` + +By the way, the other situation where an expectation may _not_ be sticky is when it's in a sequence - as soon as another expectation that comes after it in the sequence has been used, it automatically retires (and will never be used to match any call). + +## Uninteresting Calls ## +A mock object may have many methods, and not all of them are that interesting. For example, in some tests we may not care about how many times `GetX()` and `GetY()` get called. + +In Google Mock, if you are not interested in a method, just don't say anything about it. If a call to this method occurs, you'll see a warning in the test output, but it won't be a failure. + +# What Now? # +Congratulations! You've learned enough about Google Mock to start using it.

After I upgraded to a new version of Google Mock, they no longer compile. What's going on? ## + +After version 1.4.0 of Google Mock was released, we had an idea on how +to make it easier to write matchers that can generate informative +messages efficiently. We experimented with this idea and liked what +we saw. Therefore we decided to implement it. + +Unfortunately, this means that if you have defined your own matchers +by implementing `MatcherInterface` or using `MakePolymorphicMatcher()`, +your definitions will no longer compile.

As always, you +are welcome to post questions on `googlemock@googlegroups.com` if you +need any help. + +## When using Google Mock, do I have to use Google Test as the testing framework? I have my favorite testing framework and don't want to switch. ## + +Google Mock works out of the box with Google Test. However, it's easy +to configure it to work with any testing framework of your choice. +[Here](ForDummies.md#using-google-mock-with-any-testing-framework) is how. + +## How am I supposed to make sense of these horrible template errors? ## + +If you are confused by the compiler errors gcc threw at you, +try consulting the _Google Mock Doctor_ tool first. What it does is to +scan stdin for gcc error messages, and spit out diagnoses on the +problems (we call them diseases) your code has. + +To "install", run command: +``` +alias gmd='/scripts/gmock_doctor.py' +``` + +To use it, do: +``` + 2>&1 | gmd +``` + +For example: +``` +make my_test 2>&1 | gmd +``` + +Or you can run `gmd` and copy-n-paste gcc's error messages to it. + +## Can I mock a variadic function? ## + +You cannot mock a variadic function (i.e. a function taking ellipsis +(`...`) arguments) directly in Google Mock. + +The problem is that in general, there is _no way_ for a mock object to +know how many arguments are passed to the variadic method, and what +the arguments' types are. Only the _author of the base class_ knows +the protocol, and we cannot look into their head. + +Therefore, to mock such a function, the _user_ must teach the mock +object how to figure out the number of arguments and their types. One +way to do it is to provide overloaded versions of the function. + +Ellipsis arguments are inherited from C and not really a C++ feature. +They are unsafe to use and don't work with arguments that have +constructors or destructors. Therefore we recommend to avoid them in +C++ as much as possible. + +## MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter. Why? ## + +If you compile this using Microsoft Visual C++ 2005 SP1: +```cpp +class Foo { + ... + virtual void Bar(const int i) = 0; +}; + +class MockFoo : public Foo { + ... + MOCK_METHOD1(Bar, void(const int i)); +}; +``` +You may get the following warning: +``` +warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier +``` + +This is a MSVC bug. The same code compiles fine with gcc ,for +example. If you use Visual C++ 2008 SP1, you would get the warning: +``` +warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers +``` + +In C++, if you _declare_ a function with a `const` parameter, the +`const` modifier is _ignored_. Therefore, the `Foo` base class above +is equivalent to: +```cpp +class Foo { + ... + virtual void Bar(int i) = 0; // int or const int? Makes no difference. +}; +``` + +In fact, you can _declare_ Bar() with an `int` parameter, and _define_ +it with a `const int` parameter. The compiler will still match them +up. + +Since making a parameter `const` is meaningless in the method +_declaration_, we recommend to remove it in both `Foo` and `MockFoo`. +That should workaround the VC bug. + +Note that we are talking about the _top-level_ `const` modifier here. +If the function parameter is passed by pointer or reference, declaring +the _pointee_ or _referee_ as `const` is still meaningful. For +example, the following two declarations are _not_ equivalent: +```cpp +void Bar(int* p); // Neither p nor *p is const. +void Bar(const int* p); // p is not const, but *p is. +``` + +## I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it. What can I do? ## + +We've noticed that when the `/clr` compiler flag is used, Visual C++ +uses 5~6 times as much memory when compiling a mock class. We suggest +to avoid `/clr` when compiling native C++ mocks. + +## I can't figure out why Google Mock thinks my expectations are not satisfied. What should I do? ## + +You might want to run your test with +`--gmock_verbose=info`. This flag lets Google Mock print a trace +of every mock function call it receives. By studying the trace, +you'll gain insights on why the expectations you set are not met. + +## How can I assert that a function is NEVER called? ## + +```cpp +EXPECT_CALL(foo, Bar(_)) + .Times(0); +``` + +## I have a failed test where Google Mock tells me TWICE that a particular expectation is not satisfied. Isn't this redundant? ## + +When Google Mock detects a failure, it prints relevant information +(the mock function arguments, the state of relevant expectations, and +etc) to help the user debug. If another failure is detected, Google +Mock will do the same, including printing the state of relevant +expectations. + +Sometimes an expectation's state didn't change between two failures, +and you'll see the same description of the state twice. They are +however _not_ redundant, as they refer to _different points in time_. +The fact they are the same _is_ interesting information. + +## I get a heap check failure when using a mock object, but using a real object is fine. What can be wrong? ## + +Does the class (hopefully a pure interface) you are mocking have a +virtual destructor? + +Whenever you derive from a base class, make sure its destructor is +virtual. Otherwise Bad Things will happen. Consider the following +code: + +```cpp +class Base { + public: + // Not virtual, but should be. + ~Base() { ... } + ... +}; + +class Derived : public Base { + public: + ... + private: + std::string value_; +}; + +... + Base* p = new Derived; + ... + delete p; // Surprise! ~Base() will be called, but ~Derived() will not + // - value_ is leaked. +``` + +By changing `~Base()` to virtual, `~Derived()` will be correctly +called when `delete p` is executed, and the heap checker +will be happy. + +## The "newer expectations override older ones" rule makes writing expectations awkward. Why does Google Mock do that? ## + +When people complain about this, often they are referring to code like: + +```cpp +// foo.Bar() should be called twice, return 1 the first time, and return +// 2 the second time. However, I have to write the expectations in the +// reverse order. This sucks big time!!! +EXPECT_CALL(foo, Bar()) + .WillOnce(Return(2)) + .RetiresOnSaturation(); +EXPECT_CALL(foo, Bar()) + .WillOnce(Return(1)) + .RetiresOnSaturation(); +``` + +The problem is that they didn't pick the **best** way to express the test's +intent. + +By default, expectations don't have to be matched in _any_ particular +order. If you want them to match in a certain order, you need to be +explicit. This is Google Mock's (and jMock's) fundamental philosophy: it's +easy to accidentally over-specify your tests, and we want to make it +harder to do so. + +There are two better ways to write the test spec. You could either +put the expectations in sequence: + +```cpp +// foo.Bar() should be called twice, return 1 the first time, and return +// 2 the second time. Using a sequence, we can write the expectations +// in their natural order. +{ + InSequence s; + EXPECT_CALL(foo, Bar()) + .WillOnce(Return(1)) + .RetiresOnSaturation(); + EXPECT_CALL(foo, Bar()) + .WillOnce(Return(2)) + .RetiresOnSaturation(); +} +``` + +or you can put the sequence of actions in the same expectation: + +```cpp +// foo.Bar() should be called twice, return 1 the first time, and return +// 2 the second time. +EXPECT_CALL(foo, Bar()) + .WillOnce(Return(1)) + .WillOnce(Return(2)) + .RetiresOnSaturation(); +``` + +Back to the original questions: why does Google Mock search the +expectations (and `ON_CALL`s) from back to front? Because this +allows a user to set up a mock's behavior for the common case early +(e.g. in the mock's constructor or the test fixture's set-up phase) +and customize it with more specific rules later. If Google Mock +searches from front to back, this very useful pattern won't be +possible. + +## Google Mock prints a warning when a function without EXPECT\_CALL is called, even if I have set its behavior using ON\_CALL. Would it be reasonable not to show the warning in this case? ## + +When choosing between being neat and being safe, we lean toward the +latter. So the answer is that we think it's better to show the +warning. + +Often people write `ON_CALL`s in the mock object's +constructor or `SetUp()`, as the default behavior rarely changes from +test to test. Then in the test body they set the expectations, which +are often different for each test. Having an `ON_CALL` in the set-up +part of a test doesn't mean that the calls are expected. If there's +no `EXPECT_CALL` and the method is called, it's possibly an error. If +we quietly let the call go through without notifying the user, bugs +may creep in unnoticed. + +If, however, you are sure that the calls are OK, you can write + +```cpp +EXPECT_CALL(foo, Bar(_)) + .WillRepeatedly(...); +``` + +instead of + +```cpp +ON_CALL(foo, Bar(_)) + .WillByDefault(...); +``` + +This tells Google Mock that you do expect the calls and no warning should be +printed. + +Also, you can control the verbosity using the `--gmock_verbose` flag. +If you find the output too noisy when debugging, just choose a less +verbose level. + +## How can I delete the mock function's argument in an action? ## + +If you find yourself needing to perform some action that's not +supported by Google Mock directly, remember that you can define your own +actions using +[MakeAction()](CookBook.md#writing-new-actions-quickly) or +[MakePolymorphicAction()](CookBook.md#writing-new-polymorphic-actions), +or you can write a stub function and invoke it using +[Invoke()](CookBook.md#using-functionsmethodsfunctors-as-actions). + +## MOCK\_METHODn()'s second argument looks funny. Why don't you use the MOCK\_METHODn(Method, return\_type, arg\_1, ..., arg\_n) syntax? ## + +What?! I think it's beautiful. :-) + +While which syntax looks more natural is a subjective matter to some +extent, Google Mock's syntax was chosen for several practical advantages it +has. + +Try to mock a function that takes a map as an argument: +```cpp +virtual int GetSize(const map& m); +``` + +Using the proposed syntax, it would be: +```cpp +MOCK_METHOD1(GetSize, int, const map& m); +``` + +Guess what? You'll get a compiler error as the compiler thinks that +`const map& m` are **two**, not one, arguments. To work +around this you can use `typedef` to give the map type a name, but +that gets in the way of your work. Google Mock's syntax avoids this +problem as the function's argument types are protected inside a pair +of parentheses: +```cpp +// This compiles fine. +MOCK_METHOD1(GetSize, int(const map& m)); +``` + +You still need a `typedef` if the return type contains an unprotected +comma, but that's much rarer. + +Other advantages include: + 1. `MOCK_METHOD1(Foo, int, bool)` can leave a reader wonder whether the method returns `int` or `bool`, while there won't be such confusion using Google Mock's syntax. + 1. The way Google Mock describes a function type is nothing new, although many people may not be familiar with it. The same syntax was used in C, and the `function` library in `tr1` uses this syntax extensively. Since `tr1` will become a part of the new version of STL, we feel very comfortable to be consistent with it. + 1. The function type syntax is also used in other parts of Google Mock's API (e.g. the action interface) in order to make the implementation tractable. A user needs to learn it anyway in order to utilize Google Mock's more advanced features. We'd as well stick to the same syntax in `MOCK_METHOD*`! + +## My code calls a static/global function. Can I mock it? ## + +You can, but you need to make some changes. + +In general, if you find yourself needing to mock a static function, +it's a sign that your modules are too tightly coupled (and less +flexible, less reusable, less testable, etc). You are probably better +off defining a small interface and call the function through that +interface, which then can be easily mocked. It's a bit of work +initially, but usually pays for itself quickly. + +This Google Testing Blog +[post](https://testing.googleblog.com/2008/06/defeat-static-cling.html) +says it excellently. Check it out. + +## My mock object needs to do complex stuff. It's a lot of pain to specify the actions. Google Mock sucks! ## + +I know it's not a question, but you get an answer for free any way. :-) + +With Google Mock, you can create mocks in C++ easily. And people might be +tempted to use them everywhere. Sometimes they work great, and +sometimes you may find them, well, a pain to use. So, what's wrong in +the latter case? + +When you write a test without using mocks, you exercise the code and +assert that it returns the correct value or that the system is in an +expected state. This is sometimes called "state-based testing". + +Mocks are great for what some call "interaction-based" testing: +instead of checking the system state at the very end, mock objects +verify that they are invoked the right way and report an error as soon +as it arises, giving you a handle on the precise context in which the +error was triggered. This is often more effective and economical to +do than state-based testing. + +If you are doing state-based testing and using a test double just to +simulate the real object, you are probably better off using a fake. +Using a mock in this case causes pain, as it's not a strong point for +mocks to perform complex actions. If you experience this and think +that mocks suck, you are just not using the right tool for your +problem. Or, you might be trying to solve the wrong problem. :-) + +## I got a warning "Uninteresting function call encountered - default action taken.." Should I panic? ## + +By all means, NO! It's just an FYI. + +What it means is that you have a mock function, you haven't set any +expectations on it (by Google Mock's rule this means that you are not +interested in calls to this function and therefore it can be called +any number of times), and it is called. That's OK - you didn't say +it's not OK to call the function! + +What if you actually meant to disallow this function to be called, but +forgot to write `EXPECT_CALL(foo, Bar()).Times(0)`? While +one can argue that it's the user's fault, Google Mock tries to be nice and +prints you a note. + +So, when you see the message and believe that there shouldn't be any +uninteresting calls, you should investigate what's going on. To make +your life easier, Google Mock prints the function name and arguments +when an uninteresting call is encountered. + +## I want to define a custom action. Should I use Invoke() or implement the action interface? ## + +Either way is fine - you want to choose the one that's more convenient +for your circumstance. + +Usually, if your action is for a particular function type, defining it +using `Invoke()` should be easier; if your action can be used in +functions of different types (e.g. if you are defining +`Return(value)`), `MakePolymorphicAction()` is +easiest. Sometimes you want precise control on what types of +functions the action can be used in, and implementing +`ActionInterface` is the way to go here. See the implementation of +`Return()` in `include/gmock/gmock-actions.h` for an example. + +## I'm using the set-argument-pointee action, and the compiler complains about "conflicting return type specified". What does it mean? ## + +You got this error as Google Mock has no idea what value it should return +when the mock method is called. `SetArgPointee()` says what the +side effect is, but doesn't say what the return value should be. You +need `DoAll()` to chain a `SetArgPointee()` with a `Return()`. + +See this [recipe](CookBook.md#mocking-side-effects) for more details and an example. + + +## My question is not in your FAQ! ## + +If you cannot find the answer to your question in this FAQ, there are +some other resources you can use: + + 1. search the mailing list [archive](http://groups.google.com/group/googlemock/topics), + 1. ask it on [googlemock@googlegroups.com](mailto:googlemock@googlegroups.com) and someone will answer it (to prevent spam, we require you to join the [discussion group](http://groups.google.com/group/googlemock) before you can post.). + +Please note that creating an issue in the +[issue tracker](https://github.com/google/googletest/issues) is _not_ +a good way to get your answer, as it is monitored infrequently by a +very small number of people. + +When asking a question, it's helpful to provide as much of the +following information as possible (people cannot help you if there's +not enough information in your question): + + * the version (or the revision number if you check out from SVN directly) of Google Mock you use (Google Mock is under active development, so it's possible that your problem has been solved in a later version), + * your operating system, + * the name and version of your compiler, + * the complete command line flags you give to your compiler, + * the complete compiler error messages (if the question is about compilation), + * the _actual_ code (ideally, a minimal but complete program) that has the problem you encounter. diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/KnownIssues.md b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/KnownIssues.md new file mode 100644 index 000000000000..adadf5144b1b --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/docs/KnownIssues.md @@ -0,0 +1,19 @@ +As any non-trivial software system, Google Mock has some known limitations and problems.

Inside +// the statements, you can refer to the value being matched by 'arg', +// and refer to its type by 'arg_type'. +// +// The description string documents what the matcher does, and is used +// to generate the failure message when the match fails. Since a +// MATCHER() is usually defined in a header file shared by multiple +// C++ source files, we require the description to be a C-string +// literal to avoid possible side effects. It can be empty, in which +// case we'll use the sequence of words in the matcher name as the +// description. +// +// For example: +// +// MATCHER(IsEven, "") { return (arg % 2) == 0; } +// +// allows you to write +// +// // Expects mock_foo.Bar(n) to be called where n is even. +// EXPECT_CALL(mock_foo, Bar(IsEven())); +// +// or, +// +// // Verifies that the value of some_expression is even. +// EXPECT_THAT(some_expression, IsEven()); +// +// If the above assertion fails, it will print something like: +// +// Value of: some_expression +// Expected: is even +// Actual: 7 +// +// where the description "is even" is automatically calculated from the +// matcher name IsEven. +// +// Argument Type +// ============= +// +// Note that the type of the value being matched (arg_type) is +// determined by the context in which you use the matcher and is +// supplied to you by the compiler, so you don't need to worry about +// declaring it (nor can you). This allows the matcher to be +// polymorphic. For example, IsEven() can be used to match any type +// where the value of "(arg % 2) == 0" can be implicitly converted to +// a bool. In the "Bar(IsEven())" example above, if method Bar() +// takes an int, 'arg_type' will be int; if it takes an unsigned long, +// 'arg_type' will be unsigned long; and so on. +// +// Parameterizing Matchers +// ======================= +// +// Sometimes you'll want to parameterize the matcher. For that you +// can use another macro: +// +// MATCHER_P(name, param_name, description_string) { statements; } +// +// For example: +// +// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; } +// +// will allow you to write: +// +// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n)); +// +// which may lead to this message (assuming n is 10): +// +// Value of: Blah("a") +// Expected: has absolute value 10 +// Actual: -9 +// +// Note that both the matcher description and its parameter are +// printed, making the message human-friendly. +// +// In the matcher definition body, you can write 'foo_type' to +// reference the type of a parameter named 'foo'. For example, in the +// body of MATCHER_P(HasAbsoluteValue, value) above, you can write +// 'value_type' to refer to the type of 'value'. +// +// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to +// support multi-parameter matchers. +// +// Describing Parameterized Matchers +// ================================= +// +// The last argument to MATCHER*() is a string-typed expression. The +// expression can reference all of the matcher's parameters and a +// special bool-typed variable named 'negation'. When 'negation' is +// false, the expression should evaluate to the matcher's description; +// otherwise it should evaluate to the description of the negation of +// the matcher. For example, +// +// using testing::PrintToString; +// +// MATCHER_P2(InClosedRange, low, hi, +// std::string(negation ? "is not" : "is") + " in range [" + +// PrintToString(low) + ", " + PrintToString(hi) + "]") { +// return low <= arg && arg <= hi; +// } +// ... +// EXPECT_THAT(3, InClosedRange(4, 6)); +// EXPECT_THAT(3, Not(InClosedRange(2, 4))); +// +// would generate two failures that contain the text: +// +// Expected: is in range [4, 6] +// ... +// Expected: is not in range [2, 4] +// +// If you specify "" as the description, the failure message will +// contain the sequence of words in the matcher name followed by the +// parameter values printed as a tuple. For example, +// +// MATCHER_P2(InClosedRange, low, hi, "") { ... } +// ... +// EXPECT_THAT(3, InClosedRange(4, 6)); +// EXPECT_THAT(3, Not(InClosedRange(2, 4))); +// +// would generate two failures that contain the text: +// +// Expected: in closed range (4, 6) +// ... +// Expected: not (in closed range (2, 4)) +// +// Types of Matcher Parameters +// =========================== +// +// For the purpose of typing, you can view +// +// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... } +// +// as shorthand for +// +// template +// FooMatcherPk +// Foo(p1_type p1, ..., pk_type pk) { ... } +// +// When you write Foo(v1, ..., vk), the compiler infers the types of +// the parameters v1, ..., and vk for you. If you are not happy with +// the result of the type inference, you can specify the types by +// explicitly instantiating the template, as in Foo(5, +// false). As said earlier, you don't get to (or need to) specify +// 'arg_type' as that's determined by the context in which the matcher +// is used. You can assign the result of expression Foo(p1, ..., pk) +// to a variable of type FooMatcherPk. This +// can be useful when composing matchers. +// +// While you can instantiate a matcher template with reference types, +// passing the parameters by pointer usually makes your code more +// readable. If, however, you still want to pass a parameter by +// reference, be aware that in the failure message generated by the +// matcher you will see the value of the referenced object but not its +// address. +// +// Explaining Match Results +// ======================== +// +// Sometimes the matcher description alone isn't enough to explain why +// the match has failed or succeeded. For example, when expecting a +// long string, it can be very helpful to also print the diff between +// the expected string and the actual one. To achieve that, you can +// optionally stream additional information to a special variable +// named result_listener, whose type is a pointer to class +// MatchResultListener: +// +// MATCHER_P(EqualsLongString, str, "") { +// if (arg == str) return true; +// +// *result_listener << "the difference: " +/// << DiffStrings(str, arg); +// return false; +// } +// +// Overloading Matchers +// ==================== +// +// You can overload matchers with different numbers of parameters: +// +// MATCHER_P(Blah, a, description_string1) { ... } +// MATCHER_P2(Blah, a, b, description_string2) { ... } +// +// Caveats +// ======= +// +// When defining a new matcher, you should also consider implementing +// MatcherInterface or using MakePolymorphicMatcher(). These +// approaches require more work than the MATCHER* macros, but also +// give you more control on the types of the value being matched and +// the matcher parameters, which may leads to better compiler error +// messages when the matcher is used wrong. They also allow +// overloading matchers based on parameter types (as opposed to just +// based on the number of parameters). +// +// MATCHER*() can only be used in a namespace scope. The reason is +// that C++ doesn't yet allow function-local types to be used to +// instantiate templates. The up-coming C++0x standard will fix this. +// Once that's done, we'll consider supporting using MATCHER*() inside +// a function. +// +// More Information +// ================ +// +// To learn more

It will not +$$ // show up in the generated code. + + +// The MATCHER* family of macros can be used in a namespace scope to +// define custom matchers easily. +// +// Basic Usage +// =========== +// +// The syntax +// +// MATCHER(name, description_string) { statements; } +// +// defines a matcher with the given name that executes the statements, +// which must return a bool to indicate if the match succeeds. Inside +// the statements, you can refer to the value being matched by 'arg', +// and refer to its type by 'arg_type'. +// +// The description string documents what the matcher does, and is used +// to generate the failure message when the match fails. Since a +// MATCHER() is usually defined in a header file shared by multiple +// C++ source files, we require the description to be a C-string +// literal to avoid possible side effects. It can be empty, in which +// case we'll use the sequence of words in the matcher name as the +// description. +// +// For example: +// +// MATCHER(IsEven, "") { return (arg % 2) == 0; } +// +// allows you to write +// +// // Expects mock_foo.Bar(n) to be called where n is even. +// EXPECT_CALL(mock_foo, Bar(IsEven())); +// +// or, +// +// // Verifies that the value of some_expression is even. +// EXPECT_THAT(some_expression, IsEven()); +// +// If the above assertion fails, it will print something like: +// +// Value of: some_expression +// Expected: is even +// Actual: 7 +// +// where the description "is even" is automatically calculated from the +// matcher name IsEven. +// +// Argument Type +// ============= +// +// Note that the type of the value being matched (arg_type) is +// determined by the context in which you use the matcher and is +// supplied to you by the compiler, so you don't need to worry about +// declaring it (nor can you). This allows the matcher to be +// polymorphic. For example, IsEven() can be used to match any type +// where the value of "(arg % 2) == 0" can be implicitly converted to +// a bool. In the "Bar(IsEven())" example above, if method Bar() +// takes an int, 'arg_type' will be int; if it takes an unsigned long, +// 'arg_type' will be unsigned long; and so on. +// +// Parameterizing Matchers +// ======================= +// +// Sometimes you'll want to parameterize the matcher. For that you +// can use another macro: +// +// MATCHER_P(name, param_name, description_string) { statements; } +// +// For example: +// +// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; } +// +// will allow you to write: +// +// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n)); +// +// which may lead to this message (assuming n is 10): +// +// Value of: Blah("a") +// Expected: has absolute value 10 +// Actual: -9 +// +// Note that both the matcher description and its parameter are +// printed, making the message human-friendly. +// +// In the matcher definition body, you can write 'foo_type' to +// reference the type of a parameter named 'foo'. For example, in the +// body of MATCHER_P(HasAbsoluteValue, value) above, you can write +// 'value_type' to refer to the type of 'value'. +// +// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to +// support multi-parameter matchers. +// +// Describing Parameterized Matchers +// ================================= +// +// The last argument to MATCHER*() is a string-typed expression. The +// expression can reference all of the matcher's parameters and a +// special bool-typed variable named 'negation'. When 'negation' is +// false, the expression should evaluate to the matcher's description; +// otherwise it should evaluate to the description of the negation of +// the matcher. For example, +// +// using testing::PrintToString; +// +// MATCHER_P2(InClosedRange, low, hi, +// std::string(negation ? "is not" : "is") + " in range [" + +// PrintToString(low) + ", " + PrintToString(hi) + "]") { +// return low <= arg && arg <= hi; +// } +// ... +// EXPECT_THAT(3, InClosedRange(4, 6)); +// EXPECT_THAT(3, Not(InClosedRange(2, 4))); +// +// would generate two failures that contain the text: +// +// Expected: is in range [4, 6] +// ... +// Expected: is not in range [2, 4] +// +// If you specify "" as the description, the failure message will +// contain the sequence of words in the matcher name followed by the +// parameter values printed as a tuple. For example, +// +// MATCHER_P2(InClosedRange, low, hi, "") { ... } +// ... +// EXPECT_THAT(3, InClosedRange(4, 6)); +// EXPECT_THAT(3, Not(InClosedRange(2, 4))); +// +// would generate two failures that contain the text: +// +// Expected: in closed range (4, 6) +// ... +// Expected: not (in closed range (2, 4)) +// +// Types of Matcher Parameters +// =========================== +// +// For the purpose of typing, you can view +// +// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... } +// +// as shorthand for +// +// template +// FooMatcherPk +// Foo(p1_type p1, ..., pk_type pk) { ... } +// +// When you write Foo(v1, ..., vk), the compiler infers the types of +// the parameters v1, ..., and vk for you. If you are not happy with +// the result of the type inference, you can specify the types by +// explicitly instantiating the template, as in Foo(5, +// false). As said earlier, you don't get to (or need to) specify +// 'arg_type' as that's determined by the context in which the matcher +// is used. You can assign the result of expression Foo(p1, ..., pk) +// to a variable of type FooMatcherPk. This +// can be useful when composing matchers. +// +// While you can instantiate a matcher template with reference types, +// passing the parameters by pointer usually makes your code more +// readable. If, however, you still want to pass a parameter by +// reference, be aware that in the failure message generated by the +// matcher you will see the value of the referenced object but not its +// address. +// +// Explaining Match Results +// ======================== +// +// Sometimes the matcher description alone isn't enough to explain why +// the match has failed or succeeded. For example, when expecting a +// long string, it can be very helpful to also print the diff between +// the expected string and the actual one. To achieve that, you can +// optionally stream additional information to a special variable +// named result_listener, whose type is a pointer to class +// MatchResultListener: +// +// MATCHER_P(EqualsLongString, str, "") { +// if (arg == str) return true; +// +// *result_listener << "the difference: " +/// << DiffStrings(str, arg); +// return false; +// } +// +// Overloading Matchers +// ==================== +// +// You can overload matchers with different numbers of parameters: +// +// MATCHER_P(Blah, a, description_string1) { ... } +// MATCHER_P2(Blah, a, b, description_string2) { ... } +// +// Caveats +// ======= +// +// When defining a new matcher, you should also consider implementing +// MatcherInterface or using MakePolymorphicMatcher(). These +// approaches require more work than the MATCHER* macros, but also +// give you more control on the types of the value being matched and +// the matcher parameters, which may leads to better compiler error +// messages when the matcher is used wrong. They also allow +// overloading matchers based on parameter types (as opposed to just +// based on the number of parameters). +// +// MATCHER*() can only be used in a namespace scope. The reason is +// that C++ doesn't yet allow function-local types to be used to +// instantiate templates. The up-coming C++0x standard will fix this. +// Once that's done, we'll consider supporting using MATCHER*() inside +// a function. +// +// More Information +// ================ +// +// To learn more about using these macros, please search for 'MATCHER' +// on +// https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md + +$range i 0..n +$for i + +[[ +$var macro_name = [[$if i==0 [[MATCHER]] $elif i==1 [[MATCHER_P]] + $else [[MATCHER_P$i]]]] +$var class_name = [[name##Matcher[[$if i==0 [[]] $elif i==1 [[P]] + $else [[P$i]]]]]] +$range j 0..i-1 +$var template = [[$if i==0 [[]] $else [[ + + template <$for j, [[typename p$j##_type]]>\ +]]]] +$var ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] +$var impl_ctor_param_list = [[$for j, [[p$j##_type gmock_p$j]]]] +$var impl_inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(::std::move(gmock_p$j))]]]]]] +$var inits = [[$if i==0 [[]] $else [[ : $for j, [[p$j(::std::move(gmock_p$j))]]]]]] +$var params = [[$for j, [[p$j]]]] +$var param_types = [[$if i==0 [[]] $else [[<$for j, [[p$j##_type]]>]]]] +$var param_types_and_names = [[$for j, [[p$j##_type p$j]]]] +$var param_field_decls = [[$for j +[[ + + p$j##_type const p$j;\ +]]]] +$var param_field_decls2 = [[$for j +[[ + + p$j##_type const p$j;\ +]]]] + +#define $macro_name(name$for j [[, p$j]], description)\$template + class $class_name {\ + public:\ + template \ + class gmock_Impl : public ::testing::MatcherInterface<\ + GTEST_REFERENCE_TO_CONST_(arg_type)> {\ + public:\ + [[$if i==1 [[explicit ]]]]gmock_Impl($impl_ctor_param_list)\ + $impl_inits {}\ + virtual bool MatchAndExplain(\ + GTEST_REFERENCE_TO_CONST_(arg_type) arg,\ + ::testing::MatchResultListener* result_listener) const;\ + virtual void DescribeTo(::std::ostream* gmock_os) const {\ + *gmock_os << FormatDescription(false);\ + }\ + virtual void DescribeNegationTo(::std::ostream* gmock_os) const {\ + *gmock_os << FormatDescription(true);\ + }\$param_field_decls + private:\ + ::std::string FormatDescription(bool negation) const {\ + ::std::string gmock_description = (description);\ + if (!gmock_description.empty()) {\ + return gmock_description;\ + }\ + return ::testing::internal::FormatMatcherDescription(\ + negation, #name, \ + ::testing::internal::UniversalTersePrintTupleFieldsToStrings(\ + ::std::tuple<$for j, [[p$j##_type]]>($for j, [[p$j]])));\ + }\ + };\ + template \ + operator ::testing::Matcher() const {\ + return ::testing::Matcher(\ + new gmock_Impl($params));\ + }\ + [[$if i==1 [[explicit ]]]]$class_name($ctor_param_list)$inits {\ + }\$param_field_decls2 + private:\ + };\$template + inline $class_name$param_types name($param_types_and_names) {\ + return $class_name$param_types($params);\ + }\$template + template \ + bool $class_name$param_types::gmock_Impl::MatchAndExplain(\ + GTEST_REFERENCE_TO_CONST_(arg_type) arg,\ + ::testing::MatchResultListener* result_listener GTEST_ATTRIBUTE_UNUSED_)\ + const +]] + + +#endif // GMOCK_INCLUDE_GMOCK_GMOCK_GENERATED_MATCHERS_H_ diff --git a/packages/google-crc32c/crc32c/third_party/googletest/googlemock/include/gmock/gmock-generated-nice-strict.h b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/include/gmock/gmock-generated-nice-strict.h new file mode 100644 index 000000000000..91ba1d9b2c07 --- /dev/null +++ b/packages/google-crc32c/crc32c/third_party/googletest/googlemock/include/gmock/gmock-generated-nice-strict.h @@ -0,0 +1,459 @@ +// This file was GENERATED by command: +// pump.py gmock-generated-nice-strict.h.pump +// DO NOT EDIT BY HAND!!! + +// Copyright 2008, Google Inc. +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.
