### Metrics Dashboard

Track trends via artifacts:

1. **Coverage Trends**:
   - Download aggregated coverage from multiple runs
   - Compare `total-coverage.json` over time

2. **Flaky Tests**:
   - Review `flaky-tests.json` artifact
   - Track failure rates

3. **Performance**:
   - Check `metrics-history.json`
   - Monitor execution time trends

## Best Practices

### Writing Tests

✅ **DO**:
- Write tests for all new features
- Use descriptive test names
- Keep tests isolated
- Mock external services
- Maintain 80%+ coverage

❌ **DON'T**:
- Skip tests for "simple" code
- Create order-dependent tests
- Make real API calls
- Hardcode IDs or timestamps
- Commit failing tests

### Test Data

✅ **DO**:
- Use deterministic test data
- Clean up after tests
- Use test factories
- Seed consistent data

❌ **DON'T**:
- Share state between tests
- Use production data
- Leave test data behind
- Use random values without seeds

### Coverage

✅ **DO**:
- Aim for high coverage (80%+)
- Test critical paths thoroughly
- Review coverage reports
- Fix coverage drops quickly

❌ **DON'T**:
- Ignore coverage warnings
- Write tests just for coverage
- Skip edge cases
- Rely solely on coverage metrics

## Troubleshooting

### Common Issues

**Tests fail with database connection error**:
```bash
# Solution: Start Docker
pnpm docker:up
```

**Coverage below threshold**:
```bash
# Solution: View uncovered code
cd services/mana-core-auth
pnpm test:cov
open coverage/lcov-report/index.html
```

**Flaky tests detected**:
```bash
# Solution: Review test isolation
# - Check for timing issues
# - Verify proper async/await
# - Ensure cleanup in afterEach
```

**Performance regression**:
```bash
# Solution: Profile slow tests
# - Check test-results/metrics.json
# - Identify slowest tests
# - Optimize or split large tests
```

## Maintenance

### Regular Tasks

**Weekly**:
- Review flaky test reports
- Address failing tests
- Check coverage trends

**Monthly**:
- Review performance metrics
- Update test data as needed
- Clean up old artifacts

**Quarterly**:
- Audit test coverage
- Update testing documentation
- Review and improve test quality

### Updating Scripts

When modifying reporting scripts:

1. Test locally with mock data
2. Update script README
3. Test in workflow with manual trigger
4. Monitor first automated run
5. Update documentation if needed

## Future Enhancements

### Planned Improvements

1. **E2E Tests with Playwright**:
   - Browser-based testing
   - Visual regression testing
   - Cross-browser validation

2. **Test Parallelization**:
   - Optimize parallel execution
   - Reduce total workflow time
   - Smart test splitting

3. **Coverage Visualization**:
   - Interactive coverage dashboard
   - Historical trend charts
   - Per-developer coverage stats

4. **Advanced Flaky Detection**:
   - ML-based prediction
   - Auto-retry flaky tests
   - Root cause analysis

5. **Performance Baselines**:
   - Establish performance budgets
   - Block slow test commits
   - Automated optimization suggestions
