- Add OAuth unit and integration tests (passport.test.ts, auth.routes.oauth.test.ts)
- Add backup service and routes tests (backup.service.test.ts, backup.routes.test.ts)
- Set up Playwright E2E test framework with auth and recipe tests
- Add email service tests
- Increase test count from 99 to 210+ tests
- Configure Playwright for cross-browser E2E testing
- Add test coverage for critical new features (Google OAuth, Backup/Restore)
Test Coverage:
- OAuth: Comprehensive tests for Google login flow, callbacks, error handling
- Backup: Tests for creation, restoration, validation, error handling
- E2E: Authentication flow, recipe CRUD operations
- Email: SMTP configuration and template tests
This significantly improves code quality and confidence in deployments.
