test-driven-development

To implement test-driven development, write a failing test defining the intended behavior, add minimal code to pass it, then refactor. This Red-Green-Refactor cycle ensures tight feedback loops and prevents regression in feature development.

The Red-Green-Refactor cycle is a test-first workflow where you write a failing test, implement just enough code to make it pass, then refactor safely. It enforces minimal, purpose-built implementations and explicit test coverage.

Yes, test-driven development is applicable to bug fixes, refactors, and behavioral changes. You anchor the fix by writing a test that asserts expected behavior prior to coding, preventing future regressions across the workspace.

The best way to ensure minimal code is enforcing strict verification of test failures prior to implementation. By writing purpose-built tests first, you implement only enough code to pass, establishing reliable guardrails for quality assurance.

Yes, you must verify test failures prior to writing code. Test-driven development enforces strict verification of failing tests first, ensuring the test accurately captures the intended behavior before you implement the feature or fix.
