How does it enforce the 80% coverage rule?

The skill guides the user through running coverage reports (e.g., npm run test:coverage) and mandates verifying that branches, functions, and lines meet the threshold before finalizing implementation.

What test frameworks does this skill support?

The skill provides optimized patterns and workflows for Jest, Vitest, and Playwright, though its core TDD principles can be adapted to any modern testing environment.

Does it include help for mocking external dependencies?

Yes, it includes specialized patterns for mocking common services like Supabase, Redis, and OpenAI to ensure your unit and integration tests remain fast and isolated.

Can I use this for fixing bugs in existing projects?

Absolutely. It follows a specific workflow where you first write a failing test to reproduce the bug, then implement the fix to make the test pass, ensuring the bug never regresses.

Security & Testing

Enforces a rigorous test-driven development cycle with automated coverage requirements to ensure high-quality, resilient code.

The tdd-workflow skill transforms Claude into a disciplined TDD practitioner, guiding the development process through the essential Red-Green-Refactor cycle. It mandates writing tests before any functional code is implemented and enforces a strict minimum coverage threshold of 80% across unit, integration, and end-to-end testing layers. By providing standardized implementation patterns for tools like Jest, Vitest, and Playwright, this skill ensures that every new feature, bug fix, or refactor is supported by a comprehensive safety net of automated tests and clearly defined user journeys.
