QUnit vs SimpleTest comparison of testing frameworks
What are the differences between QUnit and SimpleTest?

	QUnit https://qunitjs.com/	SimpleTest https://github.com/simpletest/simpletest
Programming language	JavaScript	PHP
Category	Unit Testing	Unit Testing, Web Testing
General info	QUnit is a JS Unit testing framework. QUnit is especially useful for regression testing of jQuery, jQuery UI and jQuery Mobile projects	SimpleTest is a unit test and web test framework for PHP It has JWebUnit style functionality and support for SSL, forms, frames, proxies and basic authentication
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Yes, it is a xUnit style framework	No
Client-side Allows testing code execution on the client, such as a web browser	Yes QUnit is commonly used by jQuery, jQuery UI and jQuery Mobile It can test front-end components and functionality	Yes With SimpleTest common but fiddly PHP tasks, such as logging into a site, can be tested easily
Server-side Allows testing the bahovior of a server-side code	Yes Qunit can test any JavaScript code(including itself), this includes server-side components and functionality. Supports NodeJs	Yes Server-side behaviour can be tested by writing simple unit tests to test functionality and behaviour of single components.
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes By using the qunit-fixture element which is a container for some HTML that your tests can assert against.	Yes It can import fixtures using a mixin like 'given()' method
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.	Yes You can group fixtures together with QUnit	Yes It allows grouping of 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.		Yes Simpletest has support for generators

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)	You can use third party libraries like jQuery's Mockjax plugin	Yes It allows for one to build Mock objects.To create a mock version of a class we need to include the mock object library and run the generator. This will create a clone class which we use to create new instances(objects) in our test cases.
Grouping Allows organizing tests in groups	Yes You can use the QUnit.module() function to group tests together	Yes There are several ways of grouping tests; one is to simply place multiple test cases into a single file, another is to mark any base test cases that should not be run as abstract, Simpletest gives you a couple of options
