test-driven-development

Test-driven development improves code quality by requiring tests before implementation, reducing bugs and enhancing maintainability. This methodology enforces writing clear, concise tests to catch edge cases and verify expected behavior early.

To apply the red-green-refactor cycle, start by writing a failing test for the expected behavior, then write the minimum implementation to pass the test, and finally refactor the code iteratively. This ensures robust code development for new features.

Yes, you need understanding of basic testing principles and practices to use this approach effectively. Familiarity with software development workflows is required to enforce the methodology and write clear, concise tests for your code.

The best way to handle edge cases is to write tests specifically designed to catch potential errors before they become issues. This approach instructs you to anticipate errors during the test-writing phase, ensuring robust code development.

You should avoid TDD when lacking basic testing principles or when your software development workflow cannot accommodate iterative refactoring. The methodology requires writing failing tests first, which may not suit environments demanding immediate implementation.
