Test’em vs NaturalSpec comparison of testing frameworks
What are the differences between Test’em and NaturalSpec?

	Test’em https://github.com/testem/testem	NaturalSpec https://www.nuget.org/packages/NaturalSpec/
Programming language	JavaScript	.NET
Category	Unit Testing	Unit Testing
General info	A Unit testing test runner for JavaScript Test'em is framework agnostic and has support for Jasmine, Qunit, Mocha and others through custom test framework adapters. It canalso run tests on all major browsers as well as Node and Phantomjs	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.	It has an xUnit reporter	No
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
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
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test		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.		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
Licence Licence type governing the use and redistribution of the software		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)		Yes Mocks are available through third party libraries like Moq
Grouping Allows organizing tests in groups		N/A
