SimpleTest vs xUnit.net comparison of testing frameworks
What are the differences between SimpleTest and xUnit.net?

	SimpleTest https://github.com/simpletest/simpletest	xUnit.net https://xunit.net/
Programming language	PHP	.NET
Category	Unit Testing, Web Testing	Unit Testing
General info	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.net is aUnit testing framework for C# and .NET xUnit.net is a free, open source, community-focused unit testing tool for the .NET Framework. It is used to test C#, F#, VB.NET and other .NET languages. xUnit.net and works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation,
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes xUnit.net is part of the xUnit family of frameworks
Client-side Allows testing code execution on the client, such as a web browser	Yes With SimpleTest common but fiddly PHP tasks, such as logging into a site, can be tested easily	Yes You can test various front-end components independently since it is a Unit testing framework
Server-side Allows testing the bahovior of a server-side code	Yes Server-side behaviour can be tested by writing simple unit tests to test functionality and behaviour of single components.	Yes You can test various back-end components independently since it is a Unit testing framework
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes It can import fixtures using a mixin like 'given()' method	Yes It contains class fixtures which are setup once pertest class
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 It allows grouping of fixtures	Yes xUnit.net contains collection fixtures which allow you to share context among many tests
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)	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 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
