test-driven-development

Test-driven development is implemented by following the Red-Green-Refactor cycle, where you write a failing test first, implement minimal code to pass it, and then refactor for maintainability.

The best way to fix bugs in TDD is using the Prove-It pattern, which involves writing a failing test that reproduces the bug first, then applying the fix to ensure code correctness and prevent regressions.

The Red-Green-Refactor cycle works by first writing a failing unit test for a new feature, then writing the minimal code required to make that test pass, and finally refactoring the code to improve quality.

Yes, TDD ensures code correctness through a hierarchy of unit, integration, and E2E tests, providing a comprehensive safety net that validates individual components and overall system behavior.

You should use test-driven development when implementing new logic or fixing bugs, as it enforces a rigorous testing methodology that prevents bugs and provides a safety net for future code changes.

Refactoring plays a key role in TDD because it allows developers to improve code quality and maintainability after achieving passing tests, ensuring robust code without altering external behavior.
