What are the differences between csUnit and NaturalSpec?

	csUnit http://www.csunit.org/	NaturalSpec https://www.nuget.org/packages/NaturalSpec/
Programming language	.NET	.NET
Category	Unit Testing	Unit Testing
General info	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#	NaturalSpec is a .NET Unit testing framework NaturalSpec is a .NET UnitTest framework which provides automatically testable specs in natural language. NaturalSpec is based on NUnit and completely written in F# - you don't have to learn F# to use it.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes csUnit is an xUnit type testing framework and follows xUnit concepts	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can unit test front-end components of your applications with csUnit	Yes You can test front-end components with NaturalSpecit. It is a Unit testing framework therefore you can test front-end modules and classes independently
Server-side Allows testing the bahovior of a server-side code	Yes You can unit test back-end components of your applications with csUnit	Yes You can test back-end components with NaturalSpec. It is a Unit testing framework therefore you can test back-end modules and classes independently
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes csUnit has fixture methods such as setup and teardown methods	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.	Yes Group fixtures are available in csUnit	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.	N/A	N/A
Licence Licence type governing the use and redistribution of the software	zlib License	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)	You can write your own mock objects manually	Yes Mocks are available through third party libraries like Moq
Grouping Allows organizing tests in groups	Yes It contains recipes for combining several test assemblies into one test suite	N/A
