test-driven-development

The Red-Green-Refactor cycle in test-driven development requires writing a failing test first, implementing minimal production code to pass that test, and then refactoring the code for quality. This methodology ensures reliable software and prevents regressions.

To implement a function using test-driven development, first write a failing test for the desired behavior, then write the minimal production code required to pass the test, and finally refactor the implementation while keeping the test green.

Yes, you can use test-driven development when fixing bugs in existing software by writing a failing test that reproduces the specific bug, then writing minimal code to pass the test and ensure the regression is permanently fixed.

The best way to prevent code regressions during refactoring is enforcing a test-driven development workflow that maintains a robust test suite, ensuring existing tests pass after modifying production code to verify correctness.

Test-driven development prevents skipping tests by enforcing a rigorous Red-Green-Refactor methodology that actively addresses common rationalizations and anti-patterns, ensuring code is reliable, well-tested, and maintainable.
