Jest provides you with multiple layers on top of Jasmine.

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.

It is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework. It has several interfaces that allow the developer to choose the most comfortable. The chain-capable BDD styles provide an expressive language & readable style, while the TDD assert style provides a more classical feel.

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.

Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.

It is a really helpful library when you want to unit test your code. It supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.

Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.

It is a super-agent driven library for testing node.js HTTP servers using a fluent API. It provides a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent.

Enzyme is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Components' output.

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!

It is a modern end to end testing framework with a special BDD-style syntax. The test is written as a linear scenario of user's action on a site. Each test is described inside a Scenario function with I object passed into it.

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.

It lets you create and manage UI tests that check specific functionality in your website or application. We execute these automated browser tests continuously from the cloud and alert you if anything breaks.

Open-source, self-hosted alternative Cypress Dashboard.

It makes it painless to create automation test cases. It will efficiently record and store the case file, simply provides your website URLs.

It is a fast and simple JavaScript test runner. It offers near-instant performance and a brainless API. It makes testing tolerable.

It is a Selenium-based UI Testing Framework written in JS that’s built on top of Cucumber with Protractor for desktop / hybrid apps and Cucumber with WDIO and appium for native mobile apps.

It is a remote debugging and testing tool for JavaScript. It helps you remotely load inspect, test and debug JavaScript code running on any device with a web browser: whether it's a games console, mobile device or fridge.

It is a memory testing framework for JavaScript. It supports defining a test scenario (using Puppeteer API) that teaches Memlab how to interact with your Single-page Application (SPA), Memlab can handle the rest for memory leak checking automatically.

It is a testing tool for JavaScript (JS), which simplifies running unit tests. When you are developing a browser-based project in JS, you'll want to create unit tests and run them frequently. Typically, you'll write a unit test using some library, such as Mocha or Jasmine. These libraries let you define testcases (or "specs" if you are following a BDD style), and provide APIs for writing assertions.
