What are the differences between Test’em and JGiven?

	Test’em https://github.com/testem/testem	JGiven http://jgiven.org/

Category	Unit Testing	Acceptance Testing
General info	A Unit testing test runner for JavaScript Test'em is framework agnostic and has support for Jasmine, Qunit, Mocha and others through custom test framework adapters. It canalso run tests on all major browsers as well as Node and Phantomjs	JGiven is a BDD tool for Java in plain java.

xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	It has an xUnit reporter	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
Server-side Allows testing the bahovior of a server-side code		Yes You can write 'scenarios' to test server-side behaviours
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test
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
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
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
Grouping Allows organizing tests in groups
