Test::Unit vs Buster.JS comparison of testing frameworks
What are the differences between Test::Unit and Buster.JS?

	Test::Unit https://test-unit.github.io/	Buster.JS https://busterjs.readthedocs.io
Programming language	Ruby	JavaScript
Category	Unit Testing, Intergration Testing	Unit Testing, Browser Automation
General info	Test::Unit is a unit testing framework for Ruby Test::Unit is an implementation of the xUnit testing framework for ruby which is used for Unit Testing. However Test::Unit has been left in the standard library to support legacy test suites therefore if you are writing new test code use Minitest instead of Test::Unit	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 test-unit is a xUnit family unit testing framework for Ruby	Yes Buster.Js is a xUnit style Test Framework
Client-side Allows testing code execution on the client, such as a web browser	It could have tested some front-end components but its now legacy hence wouldn't work with the many new front-end components	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	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 Fixture methods are available through its ClassMethods Module	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 Group fixture methods are supported	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.	No
Licence Licence type governing the use and redistribution of the software	LGPLv2.1, Ruby Licence	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)	No	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	No
