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
