Risks and Mitigation

Risks

  1. Test complexity: Component Objects have many edge cases
    • Mitigation: Start with happy path tests, add edge cases iteratively
  2. Real repository issues: May uncover unexpected issues
    • Mitigation: Test early with multiple repositories
  3. Performance concerns: May need optimization
    • Mitigation: Profile early, optimize if needed
  4. Documentation time: Comprehensive docs take time
    • Mitigation: Write docs incrementally alongside tests

Next Steps

  1. ✅ Create Phase 7 plan (this document)
  2. ⏳ Set up test infrastructure
  3. ⏳ Implement Component Object unit tests
  4. ⏳ Implement core services tests
  5. ⏳ Implement editor integration tests
  6. ⏳ Write API documentation
  7. ⏳ Write integration guide
  8. ⏳ Perform real repository testing
  9. ⏳ Final validation and approval

Notes

  • Tests follow existing patterns (Jest + React Testing Library)
  • Mock data will be created for component-specific formats
  • Real repository testing will use WHO example repositories
  • Documentation will include code examples from actual implementation
  • Performance benchmarks will establish baselines for future optimization
