Test Maintenance

Adding New Tests

  1. Identify the appropriate test category (e2e, integration, unit, etc.)
  2. Create test class following existing patterns
  3. Use appropriate fixtures for setup
  4. Add clear docstrings explaining test purpose
  5. Include assertions with meaningful messages
  6. Update this documentation

Updating Existing Tests

  1. Maintain backward compatibility where possible
  2. Update test data to reflect current system behavior
  3. Adjust performance benchmarks if system improves
  4. Document any breaking changes
  5. Update related documentation

Test Review Checklist

  • Tests are properly categorized
  • Test names clearly describe what is being tested
  • Fixtures are used appropriately
  • Assertions have meaningful messages
  • Tests are independent and can run in any order
  • Performance tests have reasonable benchmarks
