How does it enforce the 80% coverage requirement?

The skill includes specific steps to run coverage reports and instructs the agent to verify that branches, functions, and lines meet the 80% threshold before concluding the development task.

Does it handle external API mocking?

Yes, it includes predefined patterns for mocking common services like Supabase, Redis, and OpenAI, ensuring that unit and integration tests remain isolated and fast.

Does this skill work with any testing framework?

While the skill provides specific patterns for Jest, Vitest, and Playwright, the TDD principles and workflow steps can be adapted to most modern JavaScript and TypeScript testing environments.

Can I use this for existing projects?

Absolutely. It is highly effective for refactoring existing code or adding new features to legacy systems by establishing a 'test-first' safety net to prevent regressions.

安全与测试

Implements comprehensive Test-Driven Development (TDD) with mandatory 80%+ coverage across unit, integration, and E2E tests.

This skill automates a disciplined Test-Driven Development (TDD) cycle within Claude Code, ensuring all new features, bug fixes, and refactorings are backed by robust tests. It guides the agent through the entire lifecycle—from defining user journeys and writing failing tests to implementation and coverage verification. By enforcing an 80% coverage threshold and providing standardized patterns for Jest, Vitest, and Playwright, it helps developers maintain high code quality, prevent regressions, and ensure that every line of code serves a verified purpose in complex web applications.
