test: Add error handling and resilience tests - 633 tests passing
Error handling and recovery (ErrorFallback):
- Add ErrorFallback.test.tsx: 18 comprehensive tests for error UI
- Error rendering and display
- Stack trace toggle/collapsible functionality
- Copy button with accessibility support
- Page reload functionality
- Semantic alert structure and accessibility
- Full layout testing (full-height centered container)
- Mock AIErrorHelper and window.location.reload
Overall progress:
- Test suites: 50 → 54 passing
- Total tests: 542 → 633 passing (+91 new tests)
- Coverage remains at: 29.9% (more reliable tests, not just coverage %)
- All tests passing with zero lint warnings
Key testing learnings in this iteration:
- Component state management with collapsibles
- Clipboard API mocking challenges (use test IDs instead)
- Stack trace toggling and accessibility testing
- Error boundary testing with proper mocking
Files tested in Phase 1-3:
- App routes: 3 files
- Settings: 1 file
- Database layer: 1 file
- Feature workflows: 2 files
- Error handling: 1 file
