The RED-GREEN-REFACTOR cycle in test-driven development involves writing a failing test, creating minimal code to pass that test, and then refactoring the code for quality. It ensures robust, maintainable software.

To apply the AAA pattern during test-driven development, you structure your tests into Arrange, Act, and Assert phases. This methodology guides you through writing failing tests first to build well-tested software.

You should use test-driven development when starting a new feature that requires robust and maintainable code. It provides a structured agile approach to writing tests before code, ensuring higher software quality.

Common TDD anti-patterns involve skipping the minimal passing code phase or neglecting refactoring for quality. Understanding the three laws of TDD helps avoid these pitfalls and maintains a clean development cycle.

The three laws of TDD dictate that you write no production code without a failing test, write only enough test code to fail, and write only enough production code to pass. They enforce the structured test-driven development workflow.
