## Test Framework and Tools
- **Framework**: Jest
- **HTTP Testing**: Supertest (for Express tests)
- **Assertions**: Jest built-in matchers
- **Mocking**: Jest mocking capabilities
- **Coverage**: Jest coverage reports
## Coverage Goals
Based on jest.config.js:
- **Branches**: 70%
- **Functions**: 75%
- **Lines**: 80%
- **Statements**: 80%
## Best Practices Followed
1. **Test Isolation**: Each test is independent and can run in any order
2. **Setup/Teardown**: Proper beforeEach/afterEach cleanup
3. **Clear Naming**: Descriptive test names that explain what is being tested
4. **Comprehensive Coverage**: Happy paths, edge cases, and error conditions
5. **Mocking**: External dependencies properly mocked
6. **Async Handling**: Proper handling of async operations
7. **Performance**: Tests complete quickly
8. **Documentation**: Tests serve as living documentation
## Test Maintenance
### Adding New Tests
1. Follow existing naming conventions
2. Add to appropriate test file or create new enhanced file
3. Include descriptive test names
4. Test both success and failure cases
5. Update this summary document
### Test Organization
- **Original tests**: Core functionality
- **Enhanced tests**: Additional edge cases and comprehensive scenarios
- **Integration tests**: End-to-end workflows
## Known Limitations
1. **Database**: Tests use in-memory storage (Map), not persistent database
2. **External Services**: No actual external API calls (all mocked)
3. **File System**: Some file operations may depend on actual file existence
4. **Timing**: Some timing-based tests may be flaky in CI environments
## Future Enhancements
1. Add E2E tests with real browser (Playwright/Puppeteer)
2. Add load testing for performance benchmarks
3. Add contract testing for API endpoints
4. Add mutation testing for test quality
5. Add visual regression testing for UI components
6. Add security scanning integration
