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

	Unit.js https://unitjs.com/	Unitils http://www.unitils.org/summary.html
Programming language	JavaScript	Java
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.	Unitils is an open source library whose goal is to make unit and integration testing easy and maintainable. Unitils is divided into modules, each of them providing support for a certain aspect of your unit and integration tests. For example if you need mocking for your tests, just include unitils-mock as a dependency, If you would also want to load DbUnit data sets, just include unitils-dbunit
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.		No
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	Yes You can perform unit tests on various components and functionality that make up the front-end
Server-side Allows testing the bahovior of a server-side code	Yes Unit.js runs in nodejs to test server-side behaviour	Yes Unitils provides support for testing the back-end through modules such as DbUnit which specifically tests your database, i.e connections setup and so on
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
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
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	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)	N/A
Grouping Allows organizing tests in groups	N/A
