test-driven-development

The Red-Green-Refactor cycle in test-driven development requires writing a failing test first, implementing minimal code to pass that test, and then refactoring the code for quality while ensuring tests remain green.

To prevent testing anti-patterns when writing unit tests, you must follow a strict test-driven development workflow that identifies common testing pitfalls and provides structural solutions to ensure code reliability and maintainability.

You should write failing tests before implementation code to enforce the test-driven development methodology, which prevents regressions, ensures high code reliability, and guarantees your software features robust and well-tested logic.

Test-driven development is applicable to all software development tasks requiring high code reliability and maintainability, guiding users through a rigorous workflow to build confidence in software reliability across any programming context.

The best way to refactor code without breaking existing tests is to follow the test-driven development methodology, ensuring you only refactor during the final phase of the Red-Green-Refactor cycle after achieving a passing test state.
