NaturalSpec vs Arquillian comparison of testing frameworks
What are the differences between NaturalSpec and Arquillian?

	NaturalSpec https://www.nuget.org/packages/NaturalSpec/	Arquillian http://arquillian.org/
Programming language	.NET	Java
Category	Unit Testing	Intergration Testing, Functional Testing
General info	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.	Arquillian is an Open source framework for writing Integration and functional tests Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It is a xUnit framework
Client-side Allows testing code execution on the client, such as a web browser	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	Yes You can perform unit tests on front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	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	Yes You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	Yes By use of extensions, for example you can use the Persistence extension to set database fixtures
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	Yes You can define group 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.	N/A	N/A

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 Mocks are available through third party libraries like Moq	Yes Arquillian supports mock object functionality you can use third party libraries
Grouping Allows organizing tests in groups	N/A	Yes Arquilian supports grouping of tests
