Contract Initialization (4 tests) +- Contract deployment verification +- Initial fee configuration +- Initial paused state +- Circuit breaker limits + +### 2. Admin Functions (22 tests) +- Pause/unpause (4 tests) +- Fee management (5 tests) +- Whitelist management (4 tests) +- Circuit breaker management (6 tests) +- Admin transfer (2 tests) +- Error conditions for unauthorized access + +### 3. Calculations (8 tests) +- Fee calculations at different rates +- Collateral requirement calculations +- Maximum flash amount calculations + +### 4. Flash Loan Execution (8 tests) +- Paused protocol rejection +- Zero amount rejection +- Unapproved receiver rejection +- Loan limit enforcement +- Collateral requirement enforcement +- Statistics tracking + +### 5. Security & Edge Cases (6 tests) +- Block volume limits +- Very small amounts +- Maximum safe amounts +- Stats accuracy across operations + +**Total: 60 tests across all files** + +## Coverage Reports + +### Interpreting Coverage + +Coverage reports show: +- **Statements**: Individual lines of code executed +- **Branches**: Decision points (if/else) tested +- **Functions**: Functions called during tests +- **Lines**: Physical lines in files tested + +Target: 80% minimum across all metrics + +### Coverage Thresholds + +Configured in `vitest.config.js`: +```javascript +coverage: { + lines: 80, + functions: 80, + branches: 80, + statements: 80, +} +``` + +## Best Practices + +### 1. Test Organization +- Group related tests in `describe` blocks +- Use descriptive test names starting with lowercase +- Follow AAA pattern: Arrange, Act, Assert + +### 2. Use beforeEach for Setup +```typescript +beforeEach(() => { + const accounts = simnet.getAccounts(); + deployer = accounts.get("deployer")!; + // ... setup code +}); +``` + +### 3. Test One Thing Per Test +```typescript +// Good +it("admin can pause protocol", () => { ... }); +it("non-admin cannot pause protocol", () => { ... }); + +// Bad +it("tests pause functionality", () => { + // Tests both admin and non-admin in one test +}); +``` + +### 4. Use Custom Matchers +```typescript +// Good - Type-safe and clear +expect(result).toBeOk(Cl.uint(5)); + +// Less ideal - Manual type checking +expect(result.type).toBe(7); +expect(result.value.value).toBe(5n); +``` + +### 5. Test Error Cases +Always test both success and failure paths: +```typescript +it("succeeds with valid input", () => { ... }); +it("fails with invalid input", () => { ... }); +it("fails when unauthorized", () => { ... }); +``` + +### 6. Document Complex Tests +```typescript +it("enforces 300% collateral ratio", () => { + // 1 sBTC (100000000 sats) requires 3 STX (300000000 ustx) + const loanAmount = 100000000; + const requiredCollateral = 300000000; + // ... test code +}); +``` + +### 7. Avoid Test Interdependence +Each test should be independent and not rely on state from other tests. + +### 8. Use Constants for Error Codes +```typescript +const ERR_UNAUTHORIZED = 102; +const ERR_INVALID_AMOUNT = 104; + +expect(result).toBeErr(Cl.uint(ERR_UNAUTHORIZED)); +``` + +## Troubleshooting + +### Common Issues + +#### 1. "Unknown contract" errors +Make sure contracts are listed in `Clarinet.toml`: +```toml +[contracts.my-contract] +path = "contracts/my-contract.clar" +clarity_version = 2 +epoch = 2.5 +``` + +#### 2. Type errors with Clarity values +Always use `Cl.*` constructors from `@stacks/transactions`: +```typescript +import { Cl } from "@stacks/transactions"; +``` + +#### 3. Tests timing out +Increase timeouts in `vitest.config.js`: +```javascript +{ + hookTimeout: 120000, + testTimeout: 120000, +} +``` + +#### 4. State bleeding between tests +Ensure `isolate: false` and `singleThread: true` in vitest config, and use `beforeEach` for setup. + +## Additional Resources + +- [Vitest Documentation](https://vitest.dev/) +- [Clarigen Documentation](https://github.com/mechanismHQ/clarigen) +- [Clarinet SDK Documentation](https://docs.hiro.so/clarinet) +- [Clarity Language Reference](https://docs.stacks.co/clarity) + +## Next Steps + +1.

This fixes cross-contract flash mint calls where tx-sender is the user, not the calling contract. Tests added (86 total, up from 60): - Successful end-to-end flash mint execution - Flash mint result data validation - Stats accumulation after successful mints - Zero sBTC supply after mint-burn cycle - Multiple sequential loans with incremental IDs - Admin transfer revokes old admin privileges - Boundary value collateral tests (exact boundary, one-below) - Single loan limit boundary tests - sbtc-token mint/burn/transfer authorization - SNP receiver v3 leverage benefit calculator - SNP receiver v3 stats and owner queries Also: Register snp-flashstack-receiver-v3 in Clarinet.toml, fix CRLF line endings in contract files.
