# TraceRTM Test Suite Summary

## Overview

Comprehensive test suites have been created for all three main components of TraceRTM: Backend (Go), CLI (Python), and Frontend (TypeScript/React). All tests are designed to avoid real API calls through extensive mocking and achieve 80%+ code coverage.

## Test Strategy & Best Practices

### No Real API Calls
✅ **Backend**: Uses in-memory SQLite database
✅ **CLI**: Mocks httpx.Client and API responses
✅ **Frontend**: Mocks global fetch function

### Comprehensive Coverage

| Component | Files | Test Cases | Focus Areas |
|-----------|-------|------------|-------------|
| Backend   | 5     | 50+        | Handlers, Models, Database |
| CLI       | 5     | 40+        | Commands, Client, Config |
| Frontend  | 6     | 45+        | Hooks, Components, Utils |

### Testing Patterns

1. **Arrange-Act-Assert** structure
2. **Isolated tests** - no dependencies between tests
3. **Mock external dependencies** - no network calls
4. **Error scenarios** - test failure cases
5. **Edge cases** - boundary conditions, empty data

# CLI
cd cli && pytest --cov

# Frontend
cd frontend/apps/web && npm run test:coverage
```

### Check Coverage

All components target **80%+ coverage** with:
- Line coverage
- Branch coverage
- Function coverage
- Statement coverage

---

## Summary Statistics

**Total Test Files**: 16
**Total Test Cases**: 135+
**Coverage Target**: 80%+

## Next Steps

1. Run tests locally to verify setup
2. Install missing dependencies if needed
3. Review coverage reports
4. Add integration tests as needed
5. Set up pre-commit hooks for running tests
