What are the differences between Buster.JS and Unit.js?

	Buster.JS https://busterjs.readthedocs.io	Unit.js https://unitjs.com/
Programming language	JavaScript	JavaScript
Category	Unit Testing, Browser Automation	Unit Testing, End-to-End Testing
General info	Buster.JS is a JavaScript test framework for node and browsers. Buster.JS is a new JavaScript testing framework. It does browser testing by automating test runs in actual browsers (think JsTestDriver), as well as Node.js testing. It has a bunch of great features.	An assertion library for JavaScript (similar to chai.js) It works with any test runner and unit testing framework like Mocha, Jasmine, Karma, protractor (E2E test framework for Angular apps) and QUnit.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Buster.Js is a xUnit style Test Framework
Client-side Allows testing code execution on the client, such as a web browser	Yes It does browser testing with browser automation, QUnit style static HTML page testing, testing in headless browsers and more front-end components and functionality	Yes Unit.js runs in the browser to test front-end components
Server-side Allows testing the bahovior of a server-side code	Yes It is a Node.js testing toolkit as well which means it can test back-end behaviour and functionality as well as run in a server environment	Yes Unit.js runs in nodejs to test server-side behaviour
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	Yes Unit.js provides Test fixtures for running testsThis is one of its features
Group fixtures Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.	N/A	Yes With Unit.js you can group your fixtures
Generators Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.
Licence Licence type governing the use and redistribution of the software	BSD License	GNU
Mocks Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)	Buster.JS ships with Sinon.JS. every test in a test case has a sandbox associated with it, making it easy to mock and stub	N/A
Grouping Allows organizing tests in groups		N/A
