test-driven-development

Test-driven development ensures code quality by enforcing the RED-GREEN-REFACTOR cycle, guiding you to write failing tests first, implement passing production code, and then refactor for maintainability.

The RED-GREEN-REFACTOR cycle is a test-driven development process where you write a failing test, write the minimum production code to make it pass, and then refactor the code to improve quality without breaking functionality.

Start writing tests before production code by creating a test for the expected behavior first, such as running a specific test function, ensuring it fails, and then implementing the feature to make it pass.

Yes, the test-first approach is suitable for software development environments where code reliability and test coverage are critical, requiring no external dependencies to enforce TDD principles.

Writing tests before code prevents regressions by verifying requirements upfront through a failing test, ensuring that subsequent production code changes are immediately validated against expected behaviors.
