The RED-GREEN-REFACTOR cycle in test-driven development involves writing a failing test, implementing minimal code to pass it, and refactoring to improve quality. It aims to enhance code maintainability.

You apply the AAA pattern by structuring tests into Arrange, Act, and Assert phases. This test-driven development approach ensures clear, concise tests by explicitly separating setup, execution, and verification steps.

Use test-driven development when aiming to improve code quality and maintainability. It is most effective when you need a structured development process that uses tests to drive design.

The three laws of TDD are fundamental rules that enforce writing tests first in the development process. They guide developers to write effective tests and implementation code incrementally to ensure better overall quality.

To write minimal code during the GREEN phase of test-driven development, implement only the logic required to make the failing test pass. This avoids unnecessary complexity and ensures your code remains focused and maintainable.

You should avoid test-driven development when exploring new prototypes or when the requirements are highly volatile. It is designed to streamline the development process for maintainable code, not for rapid, throwaway exploratory coding.
