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 clarity and robustness.

To use test-driven development for bug fixes, you first reproduce the bug by writing a failing test, implement a minimal production code fix to make the test pass, and re-run tests to confirm the fix.

Yes, test-first development supports refactoring by using existing tests as a safety net to guide safe code modifications, ensuring you maintain behavior while improving code quality and reliability.

Test-driven development works for feature development by enforcing a test-first workflow where you write a failing test for new behavior, implement just enough code to pass, and ensure correct functionality before adding features.

You should enforce test-driven development in your software workflow to ensure quality assurance by mandating the Red-Green-Refactor cycle, which prevents untested production code and ensures reliable, maintainable software.
