Vitest Testing

Vitest is a unit testing framework for JavaScript/TypeScript built on Vite. It's Jest-compatible (same API, easy migration) but significantly faster due to Vite's module resolution and native ES modules support. You write tests like you would in Jest, but they run faster and integrate seamlessly with modern build tooling. Vitest is ideal for testing frontend components, backend logic, and utilities. It supports snapshot testing, mocking, fixtures, and coverage reporting—everything Jest has, but faster.
