Describe Feature (描述功能)

We want to add integration tests for goravel/framework's features to ensure they work as expected.

1. Add full tests for the Cache module in goravel/example based on the interface: https://github.com/goravel/framework/tree/master/contracts/crypt.
2. The tests can be added in https://github.com/goravel/example/tree/master/tests/feature. Feel free to add a controller in https://github.com/goravel/example/tree/master/app/http/controllers if a request is required.
3. Let tests fail if there are bugs in the module.
4. Create a branch for the PR based on the master branch, and merge the PR to the master branch.</issue_description>

Main Features

Comprehensive Crypt Module Test Suite

Introduces a feature test suite for the Crypt module (CryptTestSuite) with complete contract-aligned coverage for encryption and decryption workflows, including:

• Round-trip encryption/decryption validation: Verifies that plaintext encrypted and then decrypted returns the original value
• Input diversity: Tests with ASCII strings, empty strings, and Unicode characters
• Non-deterministic encryption: Ensures the same plaintext encrypted multiple times produces different ciphertexts
• Error handling and edge cases: Validates decryption failures for invalid/tampered payloads and structural violations

Examples

Round-trip validation with diverse inputs:

func (s *CryptTestSuite) TestEncryptAndDecryptString() {
	values := []string{
		"goravel",
		"",
		"你好，Goravel 🚀",
	}

	for _, value := range values {
		s.Run(value, func() {
			encrypted, err := facades.Crypt().EncryptString(value)
			s.NoError(err)
			s.NotEmpty(encrypted)
			s.NotEqual(value, encrypted)

			decrypted, err := facades.Crypt().DecryptString(encrypted)
			s.NoError(err)
			s.Equal(value, decrypted)
		})
	}
}

Non-deterministic encryption verification:

func (s *CryptTestSuite) TestEncryptStringIsRandomized() {
	first, err := facades.Crypt().EncryptString("goravel")
	s.NoError(err)

	second, err := facades.Crypt().EncryptString("goravel")
	s.NoError(err)

	s.NotEqual(first, second)
}

Error path coverage for malformed and tampered payloads:

func (s *CryptTestSuite) TestDecryptStringErrors() {
	// Invalid base64/non-JSON payloads
	_, err := facades.Crypt().DecryptString("invalid-payload")
	s.Error(err)

	// Missing required fields (iv, value)
	invalidWithoutIV, _ := json.Marshal(map[string][]byte{"value": []byte("ciphertext")})
	_, err = facades.Crypt().DecryptString(base64.StdEncoding.EncodeToString(invalidWithoutIV))
	s.Error(err)
	s.ErrorContains(err, "iv")

	// Tampered ciphertext (bitwise modification)
	encrypted, _ := facades.Crypt().EncryptString("goravel")
	decoded, _ := base64.StdEncoding.DecodeString(encrypted)
	var payload map[string][]byte
	json.Unmarshal(decoded, &payload)
	payload["value"][0] ^= 0xFF
	tamperedPayload, _ := json.Marshal(payload)
	_, err = facades.Crypt().DecryptString(base64.StdEncoding.EncodeToString(tamperedPayload))
	s.Error(err)
}

The implementation uses testify/suite pattern, allows subtest identification by plaintext value, and exercises the facades.Crypt() interface methods for detecting regressions in the underlying Crypt module.

📝 Walkthrough

Walkthrough

A new test suite for the Crypt module is added, covering encryption/decryption cycles with various inputs, verifying encryption randomization, and validating error handling for malformed payloads and tampering.

Changes

Cohort / File(s)	Summary
Crypt Module Tests tests/feature/crypt_test.go	New test suite with three test cases: encrypts/decrypts various values including empty and Unicode strings, ensures encryption produces unique ciphertexts for the same plaintext, and validates error handling for invalid or tampered encrypted payloads.

🧹 Nitpick comments (2)

tests/feature/crypt_test.go (2)

28-39: Consider using a descriptive name for the empty string subtest.

When value is an empty string (line 24), s.Run(value, ...) creates a subtest with an empty name, which produces unclear test output like TestEncryptAndDecryptString/. A descriptive name would improve test readability.

✨ Proposed improvement for subtest naming

+func subtestName(value string) string {
+	if value == "" {
+		return "empty_string"
+	}
+	return value
+}
+
 func (s *CryptTestSuite) TestEncryptAndDecryptString() {
 	values := []string{
 		"goravel",
 		"",
 		"你好，Goravel 🚀",
 	}

 	for _, value := range values {
-		s.Run(value, func() {
+		s.Run(subtestName(value), func() {
 			encrypted, err := facades.Crypt().EncryptString(value)

Alternatively, use a struct-based approach with explicit names:

testCases := []struct {
	name  string
	value string
}{
	{"ascii_string", "goravel"},
	{"empty_string", ""},
	{"unicode_string", "你好，Goravel 🚀"},
}
for _, tc := range testCases {
	s.Run(tc.name, func() {
		// use tc.value
	})
}

descriptive names (e.g., map empty string to "empty_string" or switch to a slice
of structs like testCases with explicit name and value) and keep using
facades.Crypt().EncryptString and facades.Crypt().DecryptString inside the
subtest body so behavior is unchanged while s.Run receives a non-empty,
descriptive name for each case.

13-15: Consider embedding tests.TestCase for consistency with other test suites.

Most test suites in tests/feature/ (including AuthTestSuite, DBTestSuite, OrmTestSuite, etc.) embed both suite.Suite and tests.TestCase. Only CryptTestSuite and CacheTestSuite deviate from this pattern. While the tests function correctly as-is (bootstrap is handled by TestMain in main_test.go), conforming to the established pattern would improve consistency.
