It must: +- Authenticate requests securely (cookie-based and bearer token) +- Validate request payloads +- Proxy requests to Go backend correctly +- Stream responses back in AI SDK format +- Handle errors gracefully + +**Test Coverage**: +- ✅ Cookie-based authentication +- ✅ Bearer token authentication (fallback) +- ✅ 401 when no authentication provided +- ✅ Graceful error handling for auth failures +- ✅ Request validation (messages array, workspaceId) +- ✅ Invalid JSON body handling +- ✅ Proxying to Go backend with correct format +- ✅ Response streaming (SSE format) +- ✅ Go backend error handling +- ✅ Missing response body handling +- ✅ Network error handling +- ✅ Go worker URL resolution (env var, database param, default) + +**Key Test Scenarios**: +1. **Dual Authentication**: Tests both cookie-based (web) and bearer token (extension) authentication paths +2. **Request Validation**: Ensures malformed requests are rejected with appropriate error messages +3. **Proxying**: Verifies requests are correctly forwarded to Go backend with proper format +4. **Streaming**: Confirms responses are streamed back in AI SDK Data Stream Protocol format (text/event-stream) +5. **URL Resolution**: Tests priority order: env var → database param → localhost default + +### 3. `hooks/__tests__/useChatPersistence.test.tsx` (4 tests - existing, enhanced) + +**Purpose**: Tests the `useChatPersistence` hook that manages chat message persistence. + +**Why This Matters**: This hook handles loading chat history and saving completed messages to the database, ensuring chat state persists across sessions. + +**Test Coverage**: +- ✅ Loads history on mount +- ✅ Provides saveMessage function +- ✅ Skips loading when disabled +- ✅ Handles errors gracefully + +### 4. `lib/services/__tests__/chat-persistence.test.ts` (6 tests - existing) + +**Purpose**: Tests the `ChatPersistenceService` class that handles API calls for persistence. + +**Test Coverage**: +- ✅ Loads

+- ✅ Handles empty messages +- ✅ Converts multiple messages + +### 6. `__tests__/integration/chat-flow.test.tsx` (Integration tests) + +**Purpose**: Tests the end-to-end integration between

simulate authentication + +### Key Testing Patterns + +1. **Hook Testing**: Uses `@testing-library/react`'s `renderHook` for React hooks +2. **API Route Testing**: Directly imports and calls route handlers +3. **Integration Testing**: Tests component interactions without full rendering +4. **Error Scenarios**: Tests error handling at each layer + +## Why Each Test Category Matters + +### Unit Tests (useAIChat, chat-persistence, chat types) + +**Purpose**: Test individual components in isolation. + +**Benefits**: +- Fast execution +- Easy to debug failures +- Clear responsibility boundaries +- Can test edge cases thoroughly + +**Example**: Testing that `aiMessageToMessage` correctly converts AI SDK format to Chartsmith format preserves all metadata fields. + +### Integration Tests (API route, chat flow) + +**Purpose**: Test how components work together. + +**Benefits**: +- Catches integration bugs +- Verifies data flow between layers +- Tests real-world scenarios +- Ensures API contracts are met + +**Example**: Testing that a message sent through `useAIChat` → `/api/chat` → Go backend → response → persistence callback works end-to-end. + +### Error Handling Tests + +**Purpose**: Ensure system gracefully handles failures. + +**Benefits**: +- Prevents crashes +- Provides good error messages +- Maintains user experience during failures +- Helps with debugging production issues + +**Example**: Testing that when the Go backend returns 500, the API route returns a proper error response instead of crashing. + +## Test Maintenance + +### When to Add Tests + +1. **New Features**: Add tests when adding new functionality +2. **Bug Fixes**: Add regression tests when fixing bugs +3. **Refactoring**: Update tests when changing implementation +4. **Edge Cases**: Add tests when discovering edge cases + +### Running Tests + +```bash +# Run all unit tests +npm run test:unit + +# Run tests in watch mode +npm run test:watch + +# Run specific test file +npm run test:unit -- hooks/__tests__/useAIChat.test.tsx +``` + +### Test Coverage Goals + +- **Critical Paths**: 100% coverage (authentication, message conversion, API routing) +- **Error Handling**: 100% coverage (all error paths tested) +- **Integration Points**: High coverage (all major integration points tested) +- **Edge Cases**: High coverage (unusual but valid inputs tested) + +## Known Limitations + +1. **Full Component Rendering**: Some tests use simplified mocks instead of full component rendering for performance +2. **Real Backend**: Tests don't hit the actual Go backend (mocked) +3. **Real Database**: Tests don't use the actual database (mocked) +4. **E2E Tests**: Full end-to-end tests would require Playwright (separate test suite) + +## Future Improvements + +1. **E2E Tests**: Add Playwright tests for full user flows +2. **Performance Tests**: Add tests for streaming performance +3. **Load Tests**: Add tests for concurrent message handling +4. **Visual Regression**: Add tests for UI components +5. **Accessibility Tests**: Add tests for accessibility compliance + +## Conclusion + +This comprehensive test suite ensures that: +- ✅ All critical functionality is tested +- ✅ Error handling works correctly +- ✅ Integration points are verified +- ✅ Backward compatibility is maintained +- ✅ New features can be added confidently + +The tests provide confidence that the Vercel AI SDK migration is working correctly and will continue to work as the codebase evolves. diff --git a/chartsmith-app/__tests__/integration/chat-flow.test.tsx
