How does it handle external API dependencies?

The skill provides standardized mocking patterns for common services like Supabase, Redis, and OpenAI to keep tests isolated, fast, and reliable.

Does this skill help with code coverage?

Yes, it specifically enforces a minimum 80% code coverage threshold across all levels of the testing stack, including edge cases and error scenarios.

Which testing frameworks does this skill support?

The skill includes specific implementation patterns for Jest and Vitest (unit/integration) and Playwright (end-to-end testing).

What is the TDD Workflow skill for Claude?

It is a specialized capability that guides Claude to follow Test-Driven Development principles, ensuring tests are written before implementation code to guarantee high quality and coverage.

Can I use this for existing projects?

Absolutely. It is designed for writing new features, fixing existing bugs, and refactoring legacy code to ensure changes don't introduce new regressions.

보안 및 테스팅

Enforces rigorous test-driven development practices to ensure 80%+ code coverage across unit, integration, and end-to-end tests.

The TDD Workflow skill transforms Claude into a test-first engineering partner, ensuring that every new feature, bug fix, or refactor begins with a robust testing suite. By mandating a strict 'red-green-refactor' cycle, it guides developers through creating user journeys, defining complex edge cases, and implementing code that meets a minimum of 80% coverage. This skill is ideal for professional teams using TypeScript, Next.js, and Playwright who prioritize long-term maintainability and production reliability over quick, untested patches.
