Jest vs QUnit: What are the differences?

Developers describe Jest as "Painless JavaScript Unit Testing". Jest provides you with multiple layers on top of Jasmine. On the other hand, QUnit is detailed as "A JavaScript Unit Testing framework". QUnit is a powerful, easy-to-use JavaScript unit testing framework. It's used by the jQuery, jQuery UI and jQuery Mobile projects and is capable of testing any generic JavaScript code, including itself!.

Jest and QUnit can be categorized as "Javascript Testing Framework" tools.

"Open source" is the primary reason why developers consider Jest over the competitors, whereas "Simple" was stated as the key factor in picking QUnit.

Jest and QUnit are both open source tools. It seems that Jest with 26.3K GitHub stars and 3.57K forks on GitHub has more adoption than QUnit with 3.83K GitHub stars and 763 GitHub forks.

Airbnb, Facebook, and Instagram are some of the popular companies that use Jest, whereas QUnit is used by Square, Convertale, and ALV CH. Jest has a broader approval, being mentioned in 271 company stacks & 161 developers stacks; compared to QUnit, which is listed in 11 company stacks and 6 developer stacks.

    What are some alternatives to Jest and QUnit?
    Mocha
    Mocha is a feature-rich JavaScript test framework running on node.js and 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.
    Selenium
    Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
    AVA
    Even though JavaScript is single-threaded, IO in Node.js can happen in parallel due to its async nature. AVA takes advantage of this and runs your tests concurrently, which is especially beneficial for IO heavy tests. In addition, test files are run in parallel as separate processes, giving you even better performance and an isolated environment for each test file.
    Jasmine
    Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.
    Enzyme
    Enzyme is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Components' output.

    Review ofJestJest

    I'm using Jest for 3 months in a Vue JS project . I need to use a lot of custom search of related topics in jest docs because it's not clear. The examples are very poor too.

    Jest is my unit-testing tool of choice.

    Almost all unit testing suites (Mocha, Jasmine, etc.) are more or less the same.

    The main advantage I guess, is that it integrates pretty well with React and Enzyme.
