uvu is an extremely fast and lightweight test runner for Node.js and the browser, with an optional built-in assertion library. It supports async/await, native ES Modules, individually executable test files, and snapshot testing.
Use cases
- run unit tests for a Node.js project
- run tests in the browser
- test JavaScript ES modules
- add snapshot testing to assertions
- replace a heavyweight test runner with a fast minimal one
When to choose
- you want a minimal, zero-dependency test runner with fast startup
- you need browser-compatible tests
- you prefer using any assertion library, including Node's native assert
- you want individually executable test files
When to avoid
- you need built-in code coverage reporting
- you rely on advanced features like watch mode, parallel workers, or rich plugin ecosystems found in Jest or Vitest
- you need TypeScript-first tooling out of the box
