JUnit vs Buster.JS comparison of testing frameworks
What are the differences between JUnit and Buster.JS?

	JUnit https://junit.org/junit5/	Buster.JS https://busterjs.readthedocs.io
Programming language	Java	JavaScript
Category	Unit Testing, Regression Testing	Unit Testing, Browser Automation
General info	JUnit is an open source Unit testing framework for java JUnit is useful for developers to write and run repeatable tests. JUnit has been crucial in the development of test driven development and is partof the xUnit family of unit testing frameworks	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 It is an instance of the xUnit architecture for unit testing frameworks.	Yes Buster.Js is a xUnit style Test Framework
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components such as individual classes and functions that create the front-end	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 You can test classes and functions that compose the back-end such as database connections and so on	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	Yes JUnit contains a setUp() method, which runs before every test invocation and a tearDown() method, which runs after every test method.	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.	Yes You can use setUp() and tearDown() inbuilt functions as group fixtures.	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.	You can use JUnit-quickcheck to generate test data

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)	JUnit does not support mocking internally but you can use a mock framework like Mockito to generate mock objects.	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	Yes In JUnit you can create a test suite that bundles a few unit test cases and runs them together. You use both @RunWith and @Suite annotation are used to run the suite test.
