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

	Sinon.js https://sinonjs.org/	Buster.JS https://busterjs.readthedocs.io
Programming language	JavaScript	JavaScript
Category	Unit Testing	Unit Testing, Browser Automation
General info	Standalone test stubs and mocks for JavaScript. Works with any unit testing framework. Sinon.js is a great library when you want to unit test your code with supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Compatible	Yes Buster.Js is a xUnit style Test Framework
Client-side Allows testing code execution on the client, such as a web browser	Yes Sinon.js is a good library for unit testing your front-end code and has cross browser support	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
Server-side Allows testing the bahovior of a server-side code	Yes Sinon.js can run on node.js to test back-end components and server-side behaviour	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
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	N/A
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
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	New BSD License; Modified BSD License	BSD License
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)	Yes SinonJS is basically a library that we can use to create object mocks for unit testing	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
Grouping Allows organizing tests in groups
