service worker with Serwist for offline caching of dashboard and interview pages using NetworkFirst strategy - Add IndexedDB storage (Dexie) for offline interviews and cached protocols - Add Start Interview buttons to Protocols and Participants tables - Add protocol caching/downloading for offline use - Add sync status indicator in navigation bar - Add offline error boundary and indicator for interview sessions - Add offline settings section in dashboard settings - Add ENABLE_SW=true env variable for testing service worker in development - Add documentation for testing service worker

interview while completely offline +- Navigate between interview stages without network connection +- Verify data syncs automatically after reconnecting to network + +### `conflict-resolution.spec.ts`

Resolve conflicts by choosing "Keep Local" option +- Resolve conflicts by choosing "Keep Server" option +- Resolve conflicts by choosing "Keep Both" option (creates duplicate) +- Visual snapshot of the conflict resolution dialog +- Verify no conflict dialog when changes are identical +- Verify conflict indicator appears in UI when conflict is detected + +## Testing Patterns + +These tests follow the standard E2E testing patterns for the Fresco project: + +1. **Database Isolation**: Each test suite uses `database.restoreSnapshot()` in `beforeAll` to acquire a shared lock and restore the database to a known state. + +2. **Read-only vs Mutations**: Tests are organized into "Read-only" and "Mutations" describe blocks: + - Read-only tests can run in parallel across files (protected by shared lock) + - Mutation tests run serially and use `database.isolate()` for exclusive access + +3. **Element Selection**: Tests prefer semantic selectors: + - `getByRole()` for interactive elements and landmarks + - `getByTestId()` for non-semantic elements (e.g., `offline-mode-field`) + - Avoid `getByText()` to prevent brittleness + +4. **Offline Testing**: Uses Playwright's `page.context().setOffline(true/false)` to simulate network disconnection. + +## Running the Tests + +Run all offline tests: +```bash +pnpm test:e2e --grep offline +``` + +Run a specific test file: +```bash +pnpm test:e2e tests/e2e/specs/offline/enable-offline-mode.spec.ts +``` + +## Edge Cases Identified + +During implementation, the following edge cases were noted but not fully tested: + +1. **Storage Quota Exceeded**: What happens when device storage is full during protocol download? + - The current implementation shows a warning at 80% and blocks at 95% + - Need to test actual behavior when quota is exceeded mid-download + +2. **Partial Download Failure**: Network interruption during protocol asset download + - Tests should verify cleanup of partial downloads + - Should test resume capability if implemented + +3. **Multiple Simultaneous Downloads**: Downloading multiple protocols concurrently + - Current implementation may not handle this well + - Need to test queue behavior and progress tracking + +4. **Conflict Resolution Edge Cases**: + - What happens when a conflict exists for a completed interview? + - Can conflicts occur across multiple interview stages? + - How are conflicts handled if user navigates away during resolution? + +5. **Offline Mode Disabled During Active Interview**: + - What happens if offline mode is disabled while an interview is in progress offline? + - Should test data persistence and sync behavior + +6. **Service Worker Updates**: + - How does the offline functionality handle service worker updates? + - Should test cache invalidation and re-download scenarios + +7. **Interview State Corruption**: + - What happens if localStorage data becomes corrupted? + - Need validation and error recovery tests + +8. **Large Protocol Downloads**: + - Test with protocols containing many large images/videos + - Verify progress tracking accuracy and cancellation behavior + +## Future Improvements + +1. Add tests for network reconnection edge cases (intermittent connection) +2. Test offline mode with multiple concurrent interviews +3. Add performance tests for large protocol downloads +4. Test conflict resolution with complex multi-stage interview scenarios +5. Add tests for error recovery when sync fails repeatedly +6.
