Robot Framework vs wru comparison of testing frameworks
What are the differences between Robot Framework and wru?

	Robot Framework https://robotframework.org/	wru https://github.com/WebReflection/wru
Programming language	Python	JavaScript
Category	Acceptance Testing	Unit Testing
General info	Robot is a Python framework used for acceptance/functional testing Robot is an automated test framework which has a simple plain text syntax and can be extended easily with Python or Java libraries. It can run on the .net-based IronPython and on Jython which is Java based.	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.	No	Yes Wru is compatible with xUnit
Client-side Allows testing code execution on the client, such as a web browser	Yes Robot has a rich library and can also be easily integrated with Selenium for browser automation to test front-end components	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 Robot can be used for back-end tests as well	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	There is no inbuilt way to work with fixtures in Robot however it can integrate with unittest and use fixtures that way	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.	By integrating with unittest	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.	Yes Robot has a library called the Robot Framework Faker library. It contains 147 keywords used for generating random test data	N/A
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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 Robot can access Python's mock library for mocking	You can implement your stubs and mocks using a wru.assert(...) when necessary during a specific test.
Grouping Allows organizing tests in groups	Yes One can create a test suite with Robot	N/A
