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:

# Solution: Start Docker
pnpm docker:up

Coverage below threshold:

# Solution: View uncovered code
cd services/mana-core-auth
pnpm test:cov
open coverage/lcov-report/index.html

Flaky tests detected:

# Solution: Review test isolation
# - Check for timing issues
# - Verify proper async/await
# - Ensure cleanup in afterEach

Performance regression:

# 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
