From the author
Use test-driven development for behavior-changing feature or fix work, and whenever the user mentions TDD, test-first, red-green-refactor, tracer bullets, integration tests, or public-interface behavior tests. Skip for docs-only, path-only rename, formatting-only, or purely mechanical chores unless explicitly requested.

- test-driven-devzebbern/claude-code-guideTest-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.Testing★ 4.7K
- tdd-workflowmohitagw15856/pm-claude-skillsDrive a feature with a disciplined test-driven development loop — red, green, refactor. Use when implementing a feature or fixing a bug and you want tests to lead, or when asked to 'do this with TDD' / write the test first. Produces a step-by-step red-green-refactor plan: the failing test to write first, the minimal code to pass it, and the refactor — one small cycle at a time.Testing★ 1.5K
- test-driven-developmentaddyosmani/agent-skillsDrives development with tests using the red-green-refactor loop. Use when implementing any logic, fixing any bug, or changing any behavior. Use when you need to prove that code works, when a bug report arrives, or when you're about to modify existing functionality. Use when asked to add tests to a function, fix a bug in it or change its behavior, even when the code is pasted inline and the request does not mention tests.Testing★ 111.3K
- tdd-guideforyourhealth111-pixel/Vibe-SkillsTest-first development route for TDD, writing failing tests first, RED -> GREEN -> REFACTOR, and behavior-changing feature/bug/refactor work. Do not use for already-failing test root-cause debugging, test-report packaging, or final completion evidence.Testing★ 3.8K
- TDD PatternsPramodDutta/qaskillsPractice strict red-green-refactor test-driven development — write one failing test first, make it pass with the minimum code, then refactor under green, with worked cycles in Jest and pytest, AAA structure, and behavior-based test naming.Testing★ 244
- tdd-implementGulajavaMinistudio/awesome-copilot-idTest-Driven Development (TDD) and Incremental Implementation discipline. Use when implementing any feature or fixing bugs to enforce Red-Green-Refactor, vertical slicing, and atomic commits.Testing★ 91
