Zero configuration and setup for any Node.js project, and minimal setup for Browser-based projects.


QUnit can run anywhere; web browsers, Node, SpiderMonkey, even in a Web Worker! Test your code where it runs.


Flexible APIs for custom assertions, runners, and reporters mean you can extend QUnit to fit your needs.

A Quick Example

function add (a, b) {
  return a + b;

QUnit.module('add', (hooks) => {
  QUnit.test('two numbers', (assert) => {
    assert.equal(add(1, 2), 3);
