Context / Focus for Today
Major test coverage expansion day. Added 200+ new test cases across Garmin integration, AI coach, and UI components. Focused on improving coverage for low-coverage files identified in previous analysis.
Things I Got Done Today
Test Coverage Expansion
Garmin Integration Tests
- Created
token-helper.test.ts— comprehensive OAuth and token tests:- OAuth refresh token flow testing
- Token validation scenarios
- Pull token handling
- Error handling for expired/invalid tokens
- Edge cases for token refresh failures
Export Route Tests
- Created
export-route.test.ts— workout export endpoint coverage:- Payload normalization testing
- Error handling scenarios
- TCX export format validation
- FIT export format validation
- Edge cases for malformed payloads
AI Coach Tests
- Extended
json-fallback-structured.test.ts— comprehensive JSON parsing tests:- JSON extraction from various response formats
- Format parsing edge cases
- Delete/update validation scenarios
- Workout summary generation
- Truncated JSON handling and recovery
- Malformed JSON graceful degradation
Component Tests
AddWorkoutForm Tests
- Extended
AddWorkoutForm.test.tsx:- Form field validation
- Input validation scenarios
- Error handling and display
- Form submission flows
- Edge cases for invalid inputs
StructuredWorkoutBuilder Tests
- Extended
StructuredWorkoutBuilder.test.tsx:- Segment creation and editing
- Tag management
- Form field interactions
- Validation error handling
- Complex workout structure scenarios
ChatDock Tests
- Extended
ChatDock.test.tsx:- Loading state handling
- Streaming response display
- Bulk accept functionality
- Response time tracking
- Error state handling
- User interaction flows
In Progress
- Test coverage expansion (major progress today)
- Garmin integration reliability (tests added)
- AI coach quality improvements (tests added)
- Component stability (tests added)
Targets for Tomorrow
- Continue test coverage — identify remaining low-coverage areas
- CI/CD improvements — ensure all tests pass in CI pipeline
- Performance testing — add performance benchmarks for critical paths
- Integration testing — add end-to-end test scenarios
Notes / Observations
- 200+ new test cases significantly improve code reliability
- Garmin token handling now has comprehensive test coverage
- Export routes tested for all supported formats (TCX, FIT)
- AI JSON fallback parsing thoroughly tested including edge cases
- UI components have better coverage for user interactions
- Test coverage helps catch regressions before they reach production
- Investment in testing pays dividends in long-term maintainability
- All tests follow existing patterns and conventions
- Good balance between unit tests and integration-style tests
Momentum Score: 8 / 10
Strong day focused entirely on test coverage expansion. Added 200+ new test cases across 6 critical files covering Garmin integration, AI coach, and UI components. This investment in testing significantly improves code reliability and catches regressions early. While not a feature-focused day, the comprehensive test coverage provides a solid foundation for future development and ensures existing functionality remains stable.
