Does it handle external API dependencies?

Yes, the skill provides standardized patterns for mocking external services like Supabase, Redis, and OpenAI to ensure tests remain fast and deterministic.

What testing frameworks does this skill support?

The skill is optimized for Jest and Vitest for unit/integration testing, and Playwright for comprehensive browser-based end-to-end (E2E) testing.

How does it ensure code coverage requirements are met?

It includes specific steps to run coverage reports (npm run test:coverage) and verifies that branches, functions, lines, and statements meet the mandatory 80% threshold.

Can I use this for existing projects?

Absolutely. It is particularly effective for refactoring existing code or adding new functionality to an established codebase while maintaining high standards.

보안 및 테스팅

Implements a rigorous test-driven development cycle ensuring 80% code coverage across unit, integration, and end-to-end tests.

The TDD Workflow skill transforms the development process by mandating a strict 'test-first' approach for new features, bug fixes, and refactoring tasks. It guides Claude through a structured seven-step TDD cycle—starting with user journeys and failing tests through to implementation, refactoring, and coverage verification. By integrating industry-standard tools like Jest, Vitest, and Playwright, it ensures that every line of code is backed by a robust safety net, making it ideal for developers who prioritize production reliability and long-term maintainability.
