## Running the Tests
```bash
# Run all tests
npm test
# Run specific test file
npm test tests/unit/config.test.js
# Run with coverage
npm test -- --coverage
# Run in watch mode
npm run test:watch
# Run only unit tests
npm run test:unit
# Run verbose
npm run test:verbose
```
## Coverage Goals
Current coverage thresholds (from jest.config.js):
- Branches: 70%
- Functions: 75%
- Lines: 80%
- Statements: 80%
These tests exceed the minimum thresholds and provide comprehensive validation of:
- Happy paths
- Error conditions
- Edge cases
- Performance characteristics
- Security vulnerabilities
- Integration points
## Test Patterns Used
1. **AAA Pattern** (Arrange-Act-Assert)
2. **Given-When-Then** for integration tests
3. **Property-based testing** for edge cases
4. **Stress testing** for performance validation
5. **Mocking and stubbing** for external dependencies
## Future Enhancements
Potential areas for additional testing:
1. Load testing with artillery or k6
2. UI automation tests for HTML interface
3. API contract testing
4. Chaos engineering tests
5. Security penetration testing
6. Multi-user session tests
7. Database persistence tests (when implemented)
8. WebSocket/real-time communication tests (when implemented)
## Maintenance
Tests should be:
- Run on every commit (CI/CD pipeline)
- Reviewed during code reviews
- Updated when features change
- Monitored for flakiness
- Kept clean and maintainable
## Best Practices Followed
✅ Descriptive test names
✅ Isolated test cases
✅ Proper setup and teardown
✅ No test interdependencies
✅ Clear error messages
✅ Comprehensive assertions
✅ Performance benchmarks logged
✅ Edge cases documented
