Implements robust testing strategies for MERN applications using Jest, Supertest, and React Testing Library.
This skill provides a standardized framework for testing full-stack JavaScript applications built on the MERN stack. It offers pre-configured patterns for unit testing Express services, integration testing REST APIs with Supertest, and verifying React components using Testing Library. By incorporating specialized helpers like MongoMemoryServer for database isolation and MSW for network mocking, it ensures that tests are fast, reliable, and production-grade, covering everything from backend business logic to frontend user interactions.
