setup-vitest

What this skill does

Bootstraps Vitest for fast unit and integration testing. Generates a vitest.config.ts with coverage, JSDOM, and path-alias support, adds a sample test file, and wires up test, watch, and coverage scripts. Detects Vite, Next.js, and Node projects and applies the right defaults for each.

Use cases

• Replacing Jest with a faster test runner
• Adding tests to a Vite or Next.js project
• Setting up code coverage reporting
• Running tests in watch mode during development
