Javascript testing is what separates the professionals from the amateurs. frameworks are broadly classified as per Unit, Acceptance and Covergae Tools.

An overview of some of the most popular testing frameworks is listed below.

Jasmine
A behaviour-driven development framework for testing JavaScript code, does not require a DOM and is independent of other JavaScript frameworks. The script is clean and clear syntax to easily develop and write tests.

Mocha
A feature-rich framework that works on browser mode and Node.js. This simple and fun to use or asynchronous testing run serial wise and allows for accurate and flexible reporting,. It is good to map uncaught exceptions to the correct test cases.

PhantomJS
A headless WebKit scriptable with a JavaScript API, it provides fast and native support for various web standards like DOM handling, CSS selector, JSON, Canvas, and SVG.

Jest
Primarily used by Facebook for all JavaScript code including React applications.It provide an integrated “zero-configuration” experience. Ideal for engineers tits ready-to-use tools, facilitate them writing more tests, that are stable and healthy code bases.

Karma
The primary objective of this framework is i to provide a productive testing environment for developers to just write codes and access instant feedback without having to set up tedious configurations.It thus enables the work to be more productive and creative

FuncUnit
It works best on ibraries like QUnit and Jasmine, to help simulate user actions, easily test asynchronous behavior, and support black box testing. Its terse jQuery-like syntax tis best suited o superpower your functional or unit tests.

Intern
A comprehensive test system to write and run consistent, high-quality test cases for JavaScript libraries and applications. It is best suited to test any JavaScript code. It is minimally prescriptive and reinforces a basic set of best practices designed so that tests stay maintainable over time.
The extensive architecture is ideal to write custom test interfaces, executors, and reporters to influence how tests run and easily integrate with the existing coding environment.

It also comes with Grunt tasks so ias to minimise time to add to existing Grunt-based workflows, and is designed to work out-of-the-box with popular continuous integration services like Jenkins and Travis CI.

Watir
An open source Ruby library for automating tests, it human-like browser interaction: clicking links, filling out forms and validating text is good.

Istanbul
It instruments ES5 and ES2015+ JavaScript code with line counters, so one can track how well unit-tests exercise your codebase.

Enzyme
Primarily a software for React, it makes it easier to assert, manipulate, and traverse React Components’ output.It’s API is intuitive and flexible by mimicking jQuery’s API for DOM manipulation and traversal.Enzyme’s is independent of the test runner or assertion library used, and is compatible with all major test runners and assertion libraries. The documentation and examples for enzyme use mocha and chai, but one can extrapolate to a framework of choice.

testdouble.js
An opinionated, carefully-designed test double library maintained by a software agency called Test Double.It was designed to promote terse, clear, and easy-to-understand tests.

Ava
It runs tests concurrently, and is best suited for for IO heavy tests, since IO in Node.js can happen in parallel due to its async nature.Test files are run in parallel as separate processes, to better performance and an isolated environment for each test file. Switching from Mocha to AVA in Pageres brought the test time down from 31 to 11 seconds.Having tests run concurrently aids in write atomic tests, so that tests are independent of global state or the state of other tests,

Nightwatch.js
An easy, simple to use Node.js based End-to-End (E2E) testing solution for browser based apps and websites. It uses the powerful W3C WebDriver API to perform commands and assertions on DOM elements.

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

Cucumber
One of the most recommended Javascript testing frameworks, It supports over a dozen different software platforms. Every Cucumber implementation provides the same overall functionality, along with their own installation procedure and platform-specific functionality.

Wallaby.js
It provides beautiful test and code coverage reports in real time, by testing immediately as one types and displays execution results in your code editor.

TestCafe
A pure node.js end-to-end solution for testing web apps that takes care of all the stages: starting browsers, running tests, gathering test results and generating reports. TestCafe doesn’t need browser plugins – The testing framework works in all popular modern browsers out-of-the-box.

QUnit
A powerful, easy-to-use JavaScript unit test suite used by the jQuery, jQuery UI and jQuery Mobile projects . It is capable of testing any generic JavaScript code, including itself

Cypress
A test engine that runs unit and integration tests in the browser itself, Drive an application with automated tests instead of manually verifying that the app works. Saving time on set up of a test environment. Just download the desktop app, add the project and start testing immediately.

One need not change or modify the code Test in any major language or framework.

Chai
A BDD / TDD assertion library for node and browser , it can be delightfully paired with any Javascript testing framework.

CasperJS
An open source navigation scripting & testing utility written in Javascript and based on PhantomJS — the scriptable headless WebKit engine. It simplifies the process of defining a full navigation scenario and provides useful high-level functions, methods & syntactic sugar for doing common tasks

Sinon.JS
A standalone and test framework agnostic JavaScript test spies, stubs and mocks (pronounced “sigh-non”, named after Sinon, the warrior).

Zombie.js
Best recommended to write an extremely fast, headless browser,a lightweight framework for testing client-side JavaScript code in a simulated environment without any browser

Should
An expressive, readable, framework-agnostic assertion library, very helpful. It keeps the test code clean, and error messages helpful.By default the Object.prototype with a single non-enumerable getter allows \to express how objects should behave. It also returns itself when required with require.

Selenium
It automates browsers. and ideal for automating web applications for testing purposes, but not confined to that.
