QUnit is a JavaScript framework for unit testing. Originally developed for testing jQuery, jQuery UI and jQuery Mobile, it is a generic framework for testing any JavaScript code. It supports client-side environments in web browsers, and server-side (e.g. Node.js).
QUnit's assertion methods follow the CommonJS unit testing specification, which itself was influenced to some degree by QUnit.
John Resig originally developed QUnit as part of jQuery. In 2008 it was extracted from the jQuery unit test code to form its project and became known as "QUnit". This allowed others to start using it for writing their unit tests. While the initial version of QUnit used jQuery for interaction with the DOM, a rewrite in 2009 made QUnit completely standalone.
A 2017 analysis of npm and GitHub code repositories showed QUnit was the third most prevalent framework, with half as much usage as the most popular framework, Mocha.[1]
QUnit.module(string) - Defines a module, a grouping of one or more tests.QUnit.test(string, function) - Defines a test.QUnit uses a set of assertion method to provide semantic meaning in unit tests:[2]
assert.ok(boolean, string) - Asserts that the provided value casts to boolean true.assert.equal(value1, value2, message) - Compares two values, using the double-equal operator.assert.deepEqual(value1, value2, message) - Compares two values based on their content, not just their identity.assert.strictEqual(value1, value2, message) - Strictly compares two values, using the triple-equal operator.A basic example would be as follows:[3]
