What are the differences between Sinon.js and wru?

	Sinon.js https://sinonjs.org/	wru https://github.com/WebReflection/wru
Programming language	JavaScript	JavaScript
Category	Unit Testing	Unit Testing
General info	Standalone test stubs and mocks for JavaScript. Works with any unit testing framework. Sinon.js is a great library when you want to unit test your code with supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.	wru is an essential general purpose test framework compatible with web environment, node.js, Rhino, and now PhantomJS too. wru is compatible with basically all possible browsers out there included IE5.5, IE6, IE7, IE8, IE9, IE10, Chrome, Firefox, Safari, Webkit based, Mobile Browsers, and Opera. On server side wru is compatible with latest node.js, Rhino, PhantomJS, and JavaScriptCore versions.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Compatible	Yes Wru is compatible with xUnit
Client-side Allows testing code execution on the client, such as a web browser	Yes Sinon.js is a good library for unit testing your front-end code and has cross browser support	Yes Wru tests front-end components and functions, it is compatible with HTML and runs on probably all browsers
Server-side Allows testing the bahovior of a server-side code	Yes Sinon.js can run on node.js to test back-end components and server-side behaviour	Yes It is used to test back-end components and behaviour and runs in server environments
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	N/A
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	New BSD License; Modified BSD License	MIT License
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 SinonJS is basically a library that we can use to create object mocks for unit testing	You can implement your stubs and mocks using a wru.assert(...) when necessary during a specific test.
Grouping Allows organizing tests in groups		N/A
