Vitest - Unit Testing at Vite Speed
Vitest testing - blazing-fast unit tests powered by Vite. Jest API compatible, native ESM, TypeScript out-of-the-box. Test faster, deliver better.
Vitest is a fast unit-testing framework for JavaScript and TypeScript projects, integrated with the Vite tool.
Challenge
Your Jest unit tests run too slowly, ESM and TypeScript configuration requires many workarounds, and developer experience suffers. You need a faster solution compatible with existing tests.
Our Solution
Vitest is a next-generation testing framework powered by Vite. It offers native ESM and TypeScript support, Jest API compatibility, and watch mode with instant feedback. We migrate existing Jest tests to Vitest, configure code coverage, snapshot testing, and in-source testing. We integrate with CI/CD for automatic verification.
Result
Unit tests running up to 10x faster than Jest. Native TypeScript and ESM without configuration. Watch mode gives instant feedback on every code change. Your team writes and runs tests more willingly, resulting in higher code quality.
