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

	Unit.js https://unitjs.com/	Test::Unit https://test-unit.github.io/
Programming language	JavaScript	Ruby
Category	Unit Testing, End-to-End Testing	Unit Testing, Intergration Testing
General info	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.	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
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
Client-side Allows testing code execution on the client, such as a web browser	Yes Unit.js runs in the browser to test front-end components	It could have tested some front-end components but its now legacy hence wouldn't work with the many new front-end components
Server-side Allows testing the bahovior of a server-side code	Yes Unit.js runs in nodejs to test server-side behaviour	Yes
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Unit.js provides Test fixtures for running testsThis is one of its features	Yes Fixture methods are available through its ClassMethods Module
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 With Unit.js you can group your fixtures	Yes Group fixture methods are supported
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	GNU	LGPLv2.1, Ruby Licence
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)	N/A	No
Grouping Allows organizing tests in groups	N/A	No
