概要
This skill provides a comprehensive framework for setting up Vitest in TypeScript projects, prioritizing speed and modern standards through native ESM and Vite-powered execution. It automates the configuration of diverse testing environments like JSDOM and Happy-DOM, sets up robust code coverage reporting using v8, and integrates type checking directly into the test workflow. By providing standardized patterns for mocking, snapshots, and CI optimization, it helps developers establish a professional-grade testing infrastructure that is significantly faster than traditional Jest setups while remaining API-compatible.
