Vows vs NUnit comparison of testing frameworks
What are the differences between Vows and NUnit?

	Vows http://vowsjs.org/	NUnit https://nunit.org/
Programming language	JavaScript	.NET
Category	Functional Testing, Asynchronous Testing	Unit Testing
General info	Vows is a testing framework for NodeJS applications. Vows supports Asynchronous BDD & continuous testing for two reasons first, reason is that node.js is asynchronous, and therefore our tests need to be, second,is to make test suites which target I/O libraries run much faster.	NUnit is an open-source unit testing framework for Microsoft .NET. NUnit was Initially ported from JUnit. Tests can be run from a console runner, within Visual Studio through a Test Adapter or through 3rd party runners. Tests can be run in parallel and has Strong support for data driven tests. Unit supports multiple platforms including .NET Core, Xamarin Mobile, Compact Framework and Silverlight.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes Nunit is one of many programs in the xUnit family
Client-side Allows testing code execution on the client, such as a web browser	No	Yes You can test front-end components with NUnit since it is a Unit testing framework the application is isolated into diverse modules which are tested independently
Server-side Allows testing the bahovior of a server-side code	Yes Since it specifically tests Nodejs it tests back-end components and other server-side behaviours and functions	Yes You can test back-end components with NUnit, it is a Unit testing framework hence the application is isolated into diverse modules which are tested independently
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No	Yes NUnit contains the fixture methods SetUp to initialize your test environment and TearDown method to destroy a test environment
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.	No	Yes Group fixtures are available in NUnit
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

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 You can create mock objects using the third party library moq
Grouping Allows organizing tests in groups		Yes You can group tests into suites with NUnit
