Vitest Testing
Vitest is a unit testing framework built on Vite. It's Jest-compatible (same API, easier migration) but much faster. Used for testing JavaScript/TypeScript code (frontend components, backend logic, utilities). Key differentiator: Vite's speed and module resolution. Takes 1-2 weeks to master. Sits between Jest (slower, but mature) and Playwright (E2E, not unit) as the modern default for unit testing.
什麼是 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.
