test-driven-development

The Red-Green-Refactor cycle begins by writing a failing test for your new feature, then writing the minimal implementation code to pass that test, and finally refactoring the code to improve quality while ensuring tests remain green.

To prevent testing anti-patterns, you should strictly enforce writing failing tests before implementation code, which highlights common pitfalls early and ensures your testing strategy maintains high code quality and prevents regressions.

You need to write a failing test before fixing a bug to accurately verify the defect exists, ensuring your minimal code changes resolve the specific issue and prevent future regressions without altering unintended behaviors.

Yes, test-driven development enables confident refactoring by ensuring your existing test suite verifies behavior, allowing you to restructure implementation code without introducing new bugs or breaking current software functionality.

Test-driven development requires writing minimal code to pass tests to prevent over-engineering, enforce strict requirements coverage, and ensure every piece of implementation logic is directly driven by a specific, validated test case.
