The RED-GREEN-REFACTOR cycle in test-driven development is a workflow where you first write a failing test, write the minimum code to make it pass, and then refine the design. This approach reduces defects and improves software design incrementally.

To apply test-driven development to a new feature or bugfix, start by writing a focused failing test using the AAA pattern. Next, implement the minimal code to pass the test, then refactor the implementation while keeping the test green.

Yes, you can use this test-driven development workflow for team onboarding and workshops. It provides guidelines for writing focused tests, naming conventions, and incremental implementation, making it suitable for developers across various codebases and team sizes.

The three laws of test-driven development dictate writing no production code without a failing test, writing only enough test code to fail, and writing only enough production code to pass the test, enforcing the RED-GREEN-REFACTOR cycle.

Yes, test-driven development works for refactoring existing codebases. It guides teams through the RED-GREEN-REFACTOR cycle to safely modify code, ensuring tests drive iterative refinement and reduce defects during refactoring sessions.
