How does it enforce the 80% coverage rule?

The skill provides configuration templates and automated verification steps to ensure branches, functions, and lines meet the 80% minimum threshold before completion.

Does it handle external API dependencies?

Absolutely. It includes specialized mock templates for third-party services like Supabase, Redis, and OpenAI to ensure your tests remain fast and isolated.

What testing frameworks does this skill support?

It provides optimized patterns and workflows for Jest, Vitest, and Playwright, covering unit, integration, and E2E testing scenarios.

Can I use this for existing projects?

Yes, the skill includes specific workflows for refactoring existing code and adding comprehensive test suites to legacy modules safely.

安全与测试

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

This skill guides developers through a comprehensive Test-Driven Development (TDD) cycle, ensuring code quality and reliability from the very first line. By enforcing a 'test-first' mentality, it assists in drafting user journeys, generating specific test cases for frameworks like Jest, Vitest, and Playwright, and maintaining a minimum of 80% code coverage. It provides standardized implementation patterns for mocking external services such as Supabase, Redis, and OpenAI, making it an essential tool for teams building robust web applications who want to eliminate regressions and ensure production-grade stability.
