Vitest is a Vite-native test runner with Jest-compatible API, native ESM and TypeScript support, and fast HMR-like watch mode. Replacing Jest in modern projects.
Reviewer scorecard
“Vendor lock-in concerns. Hard to migrate once you're committed.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
“The API design is thoughtful. Integrates well with existing stacks.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
