1. ✅ Visual regression workflow (.github/workflows/visual-regression.yml)
2. ✅ Test fixtures and helpers for reusable test data
3. ✅ Improved test organization and structure

1. Some API Routes - Additional API route tests can be added as needed
2. Complex Integration Flows - Multi-service integration tests
3. Performance Tests - Load testing not yet implemented

1. Add Performance Tests

   • Consider adding Lighthouse CI for performance regression
   • Add load testing with k6 or Artillery

2. Expand API Tests

   • Add tests for all API routes in src/app/api/
   • Test error handling and edge cases

3. Add Mutation Testing

   • Consider Stryker for mutation testing
   • Ensure tests actually catch bugs

4. Improve E2E Stability

   • Add more wait strategies
   • Reduce flakiness in async tests

1. ✅ Run full test suite to get actual coverage numbers
2. ⚙️ Address any failing tests
3. ⚙️ Set up Percy/Chromatic for visual regression (optional)
4. ⚙️ Add performance testing setup (future)
5. ⚙️ Configure coverage thresholds in Jest config

The nself-chat project now has comprehensive test coverage across:

• ✅ 80+ unit test files covering components, hooks, stores, contexts
• ✅ 6 integration test files testing complex workflows
• ✅ 17 E2E test files covering critical user journeys
• ✅ Visual regression testing with Playwright (Percy/Chromatic ready)
