test-driven-development

The test-driven development cycle is Red-Green-Refactor: you write a failing test first, implement the minimal code to pass it, and then refactor. This ensures code correctness and prevents regressions throughout software development.

To prevent code regressions during refactoring, enforce a test-driven development process by writing failing tests before implementation. This ensures existing functionality remains intact and new code is thoroughly tested before integration.

You should write failing tests before implementing new code because it enforces testability and prevents regressions. This test-driven approach leads to cleaner, more modular, and well-documented code by addressing common testing anti-patterns.

The best way to improve code quality and maintainability is by applying test-driven development. Requiring tests to be written before implementation leads to cleaner, more modular code and ensures the software remains free from regressions.

You need to use test-driven development for bug fixes when you want to ensure code correctness and prevent future regressions. By following the Red-Green-Refactor cycle, you write a failing test that reproduces the bug before fixing it.

Yes, test-driven development works without external dependencies by enforcing the Red-Green-Refactor cycle internally. It guides users through writing failing tests, implementing minimal code, and refactoring to ensure robust software engineering practices.
