The red-green-refactor loop in test-driven development involves writing a failing test first, implementing minimal code to pass the test, then refactoring while maintaining behavioral validation. This enforces CI-ready workflows and public-interface testing.

Using a test-first workflow for bug fixes means capturing acceptance criteria in a failing test that reproduces the bug, then implementing the minimal code to pass the test. This ensures robust error handling and reduces regression risk.

The best way to structure integration testing in TDD is to emphasize behavior-first testing across integration boundaries. By validating public interfaces, tests survive internal structural changes and maintain alignment with CI-ready practices.

You need test-driven development for feature implementation when development drifts into unclear implementation. It captures behavior before coding, reducing regression risk and improving design through structured behavioral validation.

Yes, test-driven development works for refactoring by emphasizing tests of public interfaces to survive internal structural changes. It maintains alignment between tests and code throughout the red-green-refactor loop.
