test-driven-development

The Red-Green-Refactor cycle in test-driven development mandates writing a failing test first, implementing the minimal code required to pass that test, and finally refactoring the code while verifying all tests still pass.

To prevent regressions when refactoring code, enforce a rigorous test-driven development methodology by writing failing tests before implementation and verifying all tests pass before and after modifying the codebase.

You should always write a failing test before writing implementation code when developing new features, fixing bugs, or refactoring tasks to ensure code quality and prevent future regressions.

Test-driven development improves code quality and software design by encouraging developers to write modular, testable code, ensuring new features work as intended and are robust against future changes.

The best way to start TDD for a new feature is to write a failing test that defines the desired behavior, then write the minimal implementation code to pass the test, and finally refactor the code for better design.

Yes, you can use the TDD methodology for fixing bugs and refactoring tasks by writing a failing test that reproduces the bug before implementation, ensuring the fix works and preventing regressions.
