# Test Suite Summary
## Test Coverage Created
### Total Tests: **48 tests**
- ✅ **9 unit tests** in lib (configuration/rule modules)
- ✅ **9 unit tests** in main binary
- ✅ **4 configuration loading tests**
- ✅ **5 integration tests**
- ✅ **6 intermediary conversion tests**
- ✅ **7 plugin system tests**
- ✅ **8 rule matching tests**
All tests **PASSING** ✨
## Test Structure
### Unit Tests (Embedded in Source)
- `src/configuration/rule/when.rs` - When clause deserialization
- `src/configuration/rule/then.rs` - Then clause variants (Mock, Proxy, Fips, Static)
- `src/configuration/rule/with.rs` - With clause (probability, plugins, sleep)
### Integration Tests (`tests/` directory)
1. **configuration_tests.rs** - YAML loading, deserialization, path handling
2. **rule_matching_tests.rs** - URI patterns, methods, body matching, probability
3. **intermediary_tests.rs** - Request/response conversions, header preservation
4. **plugin_tests.rs** - Function invocation, argument validation, error handling
5. **integration_tests.rs** - End-to-end pipeline, concurrent evaluation
### Test Utilities
- `tests/common/mod.rs` - Shared helper functions for creating test objects
## Key Features Tested
### Configuration Loading
- ✅ Load rules from directories
- ✅ Filter by file extension (`.nrule.yml`)
- ✅ Handle invalid paths gracefully
- ✅ Deserialize all rule types
- ✅ Error handling for malformed YAML
### Rule Matching
- ✅ Single and multiple URI patterns
- ✅ HTTP method matching
- ✅ Body content matching
- ✅ Probability-based selection
- ✅ Combined condition evaluation
### Intermediary Conversions
- ✅ Request → Intermediary
- ✅ Response → Intermediary
- ✅ Intermediary → Request
- ✅ Intermediary → Response
- ✅ Header preservation
- ✅ Status code handling
- ✅ Missing field validation
### Plugin System
- ✅ Function invocation with/without arguments
- ✅ Argument count validation
- ✅ Error type handling (InvalidArgumentCount, Other)
- ✅ Help text support
- ✅ Array vs object argument handling
### Integration
- ✅ Full configuration loading pipeline
- ✅ Rule container matching with real configs
- ✅ Multiple rules precedence
- ✅ Concurrent rule evaluation (10 parallel tasks)
- ✅ Error handling pipeline
## Test Execution
### Run All Tests
```bash
cargo test
# Or use the test script:
./scripts/run_tests.sh
```
### Run Specific Test Suite
```bash
cargo test --test configuration_tests
cargo test --test rule_matching_tests
cargo test --test integration_tests
```
### Run with Coverage
```bash
./scripts/run_tests.sh --coverage
```
## CI/CD Integration
GitHub Actions workflow created at `.github/workflows/tests.yml`:
- Runs on push to main and upgrade-hyper-sonnet branches
- Tests on Ubuntu and macOS
- Includes formatting, clippy, and coverage checks
- Caches dependencies for faster builds
## Test Quality Metrics
- **Coverage**: Comprehensive coverage of core functionality
- **Footprint**: Minimal - only 5 test files + common utilities
- **Speed**: All tests complete in < 1 second
- **Maintainability**: Clear test names, focused assertions
- **Reliability**: No flaky tests, deterministic results
## Files Created/Modified
### New Files
- `tests/common/mod.rs` - Test utilities
- `tests/configuration_tests.rs` - Configuration loading
- `tests/rule_matching_tests.rs` - Rule matching logic
- `tests/intermediary_tests.rs` - Type conversions
- `tests/plugin_tests.rs` - Plugin system
- `tests/integration_tests.rs` - End-to-end tests
- `TESTING.md` - Test documentation
- `scripts/run_tests.sh` - Test runner script
- `.github/workflows/tests.yml` - CI configuration
- `TEST_SUMMARY.md` - This file
### Modified Files
- `src/lib.rs` - Exported `configuration` module
- `src/configuration/loader.rs` - Made `extensions` public, improved error handling
- `src/configuration/rule/when.rs` - Added unit tests
- `src/configuration/rule/then.rs` - Added unit tests
- `src/configuration/rule/with.rs` - Added unit tests
- `src/configuration/rule/mod.rs` - Fixed body matching to use `to_string()`
## Next Steps
### Recommended Enhancements
1. **Property-based testing** with `proptest` for rule matching
2. **Fuzzing** for YAML parser robustness
3. **Load testing** for server endpoints
4. **Mutation testing** with `cargo-mutants`
5. **Coverage tracking** with codecov.io integration
### Maintenance
- Run tests before each commit: `cargo test`
- Check coverage periodically: `./scripts/run_tests.sh --coverage`
- Update tests when adding new features
- Keep test documentation in sync with code changes
## Performance
Test execution is fast and efficient:
- Unit tests: ~0.00s each suite
- Integration tests: ~0.01-0.02s
- Total test time: < 1 second
- Parallel execution supported: `cargo test -- --test-threads=4`
