Summary
This gives Claude expertise in Vitest, the Vite-powered testing framework that's become the go-to for modern TypeScript and JavaScript projects. You get comprehensive coverage of the testing workflow: setup with vitest.config.ts, writing tests with describe/it blocks, parametrized tests, mocking functions and modules, timer manipulation, and coverage reporting. The skill emphasizes using bun as the test runner and includes practical patterns for both unit and integration testing. Honestly, if you're already using Vite for your build tooling, Vitest is the obvious choice since it shares the same config and transform pipeline. The examples are solid and cover the full assertion API plus real-world scenarios like API endpoint testing.
