Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
