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

	JGiven http://jgiven.org/	Unit.js https://unitjs.com/
Programming language	Java	JavaScript
Category	Acceptance Testing	Unit Testing, End-to-End Testing
General info	JGiven is a BDD tool for Java in plain java. With JGiven Developers write scenarios in plain Java using a fluent, domain-specific API, JGiven generates reports that are readable by domain experts.	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.
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 You can test UI functionality or behaviour by writing scenarios that cover front-end behaviour	Yes Unit.js runs in the browser to test front-end components
Server-side Allows testing the bahovior of a server-side code	Yes You can write 'scenarios' to test server-side behaviours	Yes Unit.js runs in nodejs to test server-side behaviour
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.	N/A	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.	N/A
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)	Yes You can use third party libraries such as JMock and JMockit to mock objects and functions	N/A
Grouping Allows organizing tests in groups		N/A
