QUnit is a powerful, easy-to-use JavaScript unit testing framework. It is used to test any generic JavaScript code, including code running in the browser or in Node.js. QUnit is especially useful for testing jQuery projects.
Basic Test
This feature allows you to write a basic test case. The `QUnit.test` function defines a test with a name and a callback function. The `assert.ok` method checks if the given expression is true.
QUnit.test('hello test', function(assert) {
assert.ok(1 == '1', 'Passed!');
});Asynchronous Testing
QUnit supports asynchronous testing. You can use async/await to handle asynchronous operations within your tests. The test will wait for the promise to resolve before making assertions.
QUnit.test('asynchronous test: async and await', async function(assert) {
const result = await new Promise(resolve => setTimeout(() => resolve('done'), 1000));
assert.equal(result, 'done', 'Passed!');
});Module Grouping
QUnit allows you to group related tests using `QUnit.module`. You can also define setup and teardown logic using hooks like `beforeEach` and `afterEach`.
QUnit.module('group a', function(hooks) {
hooks.beforeEach(function(assert) {
assert.ok(true, 'beforeEach called');
});
QUnit.test('a basic test example', function(assert) {
assert.ok(true, 'this test is fine');
});
});Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Compared to QUnit, Mocha is more flexible and can be paired with various assertion libraries like Chai.
Jest is a delightful JavaScript Testing Framework with a focus on simplicity. It works out of the box for most JavaScript projects and provides a rich API for writing tests. Jest includes built-in assertion libraries and mocking capabilities, making it a more integrated solution compared to QUnit.
Jasmine is a behavior-driven development framework for testing JavaScript code. It does not depend on any other JavaScript frameworks and does not require a DOM. Jasmine is known for its easy-to-read syntax and is often compared to QUnit for its simplicity and ease of use.
QUnit is a powerful, easy-to-use JavaScript testing framework. It was originally developed for the jQuery project and has since evolved to test any client-side or server-side JavaScript code. QUnit has no dependencies and supports Node.js, SpiderMonkey, and all major web browsers.
