What are the differences between testdouble.js and Jnario?

	testdouble.js https://github.com/testdouble/testdouble.js	Jnario http://jnario.org/
Programming language	JavaScript	Java
Category	Unit Testing, Intergration Testing	Acceptance Testing, Unit Testing
General info	This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development) Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.	Jnario is a test framework for Java focusing on the design and documentation aspects of testing Jnario is based on Xtend and consists of two domain-specific languages, one for writing readable acceptance tests, the other for succinct unit tests. Together they are well suited for behavior-driven development of Java programs.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes It is compatible with xUnit and supportsxUnit XML output	Yes It is an xUnit type testing framework
Client-side Allows testing code execution on the client, such as a web browser	No	Yes You can write scenarios to test various front-end behaviours using 'Given', 'When', 'Then' steps to describe simple scenarios
Server-side Allows testing the bahovior of a server-side code	Yes Testdouble is primarily used to test server-side functions, behaviours and components	Yes You can write unit tests to test server side behaviours and components using Jnario specs
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	Yes It contains the Setup & Teardown functions similar to JUnit but less verbose
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 The Setup & Teardown functions can be used as group 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	MIT License	Eclipse Public License v1.0
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 Testdouble includes inbuilt support for mocking	Yes You can implement mocking through the use of a third partylibrary like Mockito
Grouping Allows organizing tests in groups	N/A	Yes Jnario Suites allows you to group multiple specifications into suites and execute them together, you do this using the suite wizard
