What testing frameworks does this skill support?

While it provides specific patterns for Jest, Vitest, and Playwright, the core TDD principles and workflow can be adapted to any testing framework in your tech stack.

Can it help with mocking external services?

Absolutely. It includes best-practice patterns for mocking databases like Supabase, cache layers like Redis, and AI services like OpenAI to ensure unit tests remain fast and isolated.

Does this skill help with E2E testing?

Yes, it includes detailed patterns for Playwright to cover critical user flows, browser automation, and UI interactions as part of the complete testing lifecycle.

How is the 80% coverage requirement enforced?

The skill provides instructions for configuring coverage thresholds in your test runner and prompts you to run verification reports as a final step in the development cycle.

How does the TDD Workflow skill handle existing code?

It guides you through writing tests for current functionality before refactoring, ensuring that any changes maintain existing behavior while reaching the 80% coverage threshold.

安全与测试

Enforces rigorous test-driven development practices with mandatory 80% coverage requirements across unit, integration, and E2E tests.

The TDD Workflow skill transforms Claude into a test-first engineering partner, ensuring that every feature, bug fix, or refactor begins with comprehensive test definitions. It provides structured guidance for the Red-Green-Refactor cycle, integrates coverage thresholds for production-grade reliability, and includes ready-to-use patterns for modern testing libraries like Jest and Playwright. This skill is ideal for developers prioritizing software quality and long-term maintainability by mandating coverage for edge cases, error scenarios, and critical user journeys before code is even written.
