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
“Best instruction-following of any model. Tool use and extended thinking are reliable. The API design is clean.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Claude consistently produces the most useful outputs for real work. The longer context window is a genuine advantage.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Anthropic's focus on safety without sacrificing capability is the right approach. Claude keeps getting better.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
