RSpec vs csUnit comparison of testing frameworks
What are the differences between RSpec and csUnit?

	RSpec https://rspec.info	csUnit http://www.csunit.org/
Programming language	Ruby	.NET
Category	Unit Testing, Intergration Testing	Unit Testing
General info	Domain Specific Language (DSL) testing solution for Ruby code It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks.	csUnit is an open source unit testing tool for the .NET Framework csUnit is designed to work with any .NET compliant language. It has specifically been tested with C#, Visual Basic .NET, Managed C++, and J#
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification.	Yes csUnit is an xUnit type testing framework and follows xUnit concepts
Client-side Allows testing code execution on the client, such as a web browser	Yes RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that.	Yes You can unit test front-end components of your applications with csUnit
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side behaviour with Rspec	Yes You can unit test back-end components of your applications with csUnit
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes RSpec does contain fixture methods	Yes csUnit has fixture methods such as setup and teardown methods
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 Group fixture methods are supported	Yes Group fixtures are available in csUnit
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 RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	zlib 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 Available through rspec-mocks gem.	You can write your own mock objects manually
Grouping Allows organizing tests in groups	Yes Allows declaring example groups and contexts.	Yes It contains recipes for combining several test assemblies into one test suite
