The test-driven development cycle requires writing a failing test, implementing the minimum code to pass it, and then refactoring. This ensures features are built with a robust testing foundation from the start.

To implement features test-first, write failing tests for your scenarios before writing the implementation logic. Once the tests pass, refactor the code to improve quality while maintaining the passing tests.

Yes, the Red-Green-Refactor workflow can be applied during code reviews to verify that a test-first methodology was followed, ensuring failing tests were written prior to implementation code.

The best way to enforce test-first methodology is to strictly adhere to the Test-Driven Development cycle, guiding development to satisfy the requirement of writing failing tests prior to code.

You should refactor code during the final phase of the test-driven development cycle, immediately after your tests pass. This encourages cleaning up code while ensuring the existing tests remain green.
