Best Alternatives to jest

Delightful JavaScript testing with a focus on simplicity

Why look for an alternative?

Jest was built before native ESM and Vite. In Vite-based projects, Jest requires separate configuration and doesn't benefit from Vite's speed. Vitest has emerged as the natural replacement with a Jest-compatible API.
