What are the differences between Google Puppeteer and wru?

	Google Puppeteer https://developers.google.com/web/tools/puppeteer	wru https://github.com/WebReflection/wru
Programming language	JavaScript	JavaScript
Category	Browser Automation	Unit Testing
General info	Puppeteer is a Node library which provides browser automation for chrome and chromium Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium; It provides a high-level API to control Chromium or Chrome over the DevTools Protocol	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 Most things you can do manually in the browser can be done using puppeteer, therefore you can create a testing environment for your tests to run directly. You can test front-end functionality such as UI testing with puppeteer	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	No	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	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.	No	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)	No	You can implement your stubs and mocks using a wru.assert(...) when necessary during a specific test.
Grouping Allows organizing tests in groups	No	N/A
