How does the skill enforce the 80% coverage rule?

It provides specific steps to verify coverage reports and includes configuration patterns for coverage thresholds in your project settings.

Which testing frameworks are supported by this skill?

The skill is optimized for modern JavaScript/TypeScript stacks, primarily using Jest or Vitest for unit and integration tests, and Playwright for end-to-end testing.

Does it handle external dependencies like databases?

Yes, it includes sophisticated mocking patterns for Supabase, Redis, and AI services to ensure tests remain fast, isolated, and deterministic.

Can I use this for existing projects without tests?

Yes, it is highly effective for refactoring existing code by first establishing a baseline of tests before implementing any functional changes.

セキュリティとテスト

Enforces a strict Test-Driven Development cycle with comprehensive coverage requirements to ensure high-quality, bug-free code.

This skill guides Claude through a rigorous Test-Driven Development (TDD) workflow, ensuring that testing is never an afterthought. It mandates a 'test-first' approach for new features, bug fixes, and refactoring by following the Red-Green-Refactor cycle. The skill is designed to achieve at least 80% code coverage using a multi-layered testing strategy that includes unit tests for logic, integration tests for API and database interactions, and end-to-end browser automation with Playwright. By providing standardized patterns for mocking external services and validating user journeys, it helps developers build resilient applications with confidence.
