Next Steps

  1. Run Integration Tests:

    npm run test:coverage

  2. Verify Coverage >85%:

    • Check coverage report in coverage/ directory
    • Ensure all new components meet threshold

  3. Run E2E Tests:

    npm run test:e2e

  4. CI Integration:

    • Add test commands to CI pipeline
    • Set up parallel test execution
    • Configure coverage reporting

  5. Performance Monitoring:

    • Track test execution times
    • Optimize slow tests
    • Add performance budgets
