MCP App StoreMCP App StoreThis skill adds a comprehensive testing playbook for fullstack JavaScript/TypeScript projects. It provides concrete guidance on unit, integration, and end-to-end (E2E) testing, recommended tooling (Jest/Vitest, React Testing Library, Supertest, Playwright/Cypress), coverage targets, and test organization patterns. It also outlines practical examples and code snippets for arranging Arrange-Act-Assert tests and maintaining test hygiene.
Use this skill when you need to: set up or review test strategy for React/Next.js/NestJS apps; write unit or integration tests; design E2E flows; audit test coverage and quality; or establish test infrastructure and mocking conventions. Triggers include tasks like "write tests", "improve coverage", "setup E2E", or "audit test suite".
