Continuous Integration

Pre-commit Checks

npm test -- test/unit/ --verbose

Pre-push Checks

npm test -- --coverage

CI/CD Pipeline

npm test -- --coverage --watchAll=false

Known Test Limitations

  1. Mock Inquirer: Uses jest.spyOn for prompt verification (actual CLI not tested)
  2. File System: Uses temporary directories (safe from actual file corruption)
  3. Network: No network dependencies
  4. External Services: None required

Next Steps

  1. ✅ Write tests (COMPLETE)
  2. Implement configuration loader
  3. Implement update detection
  4. Implement question skipping
  5. Run all tests and verify pass
  6. Add to CI/CD pipeline
  7. Monitor test coverage
  8. Maintain tests with code changes

Test Maintenance

Adding New Tests

  1. Place in appropriate test file (unit or integration)
  2. Follow naming convention: it('should [expected behavior]')
  3. Include beforeEach/afterEach cleanup
  4. Add to test count in this document
  5. Update success criteria if applicable

Updating Tests

  1. Keep tests focused and independent
  2. Use descriptive names
  3. Add comments for complex assertions
  4. Update this document with changes
  5. Ensure no duplication

Debugging Tests

# Run single test file
npm test -- test/unit/config-loader.test.js
