Known Issues & Limitations

Jest Configuration

ESLint Warnings

Issue: console.log in test files, any types in test mocks Impact: 271 lint problems in test/script files Solution: Acceptable in test code, production code is clean Status: Non-blocking

E2E Test Runtime

Issue: E2E tests take 15-20 minutes (scraping + AI calls) Impact: Slow CI/CD pipeline Solution: Run in parallel with 4 workers (~5-8 minutes) Status: Acceptable

  4. Production Deploy: Deploy to Azure Container Apps
  5. Cosmos DB Config: Verify connection strings in prod environment

Maintenance Guidelines

Adding New Features

  1. Define types first in types/
  2. Create service layer in lib/
  3. Add API route in app/api/
  4. Build UI components
  5. Write tests (unit + E2E)
  6. Use Winston logger (never console.log)
  7. Document in CLAUDE.md

Running Tests

npm test                 # Unit tests (fast, ~12s)
npm run test:coverage    # With coverage report
npm run test:e2e         # E2E tests (slow, ~15-20min)
npm run test:e2e:ui      # Interactive mode

Database Operations

# Test database connection
npx tsx scripts/test-database-services.ts

# Check Cosmos DB health
curl http://localhost:3000/api/health

Logging

# Production logs
tail -f logs/combined.log
tail -f logs/error.log

# Set log level
export LOG_LEVEL=debug  # or info, warn, error
