What are the differences between NUnit and MSTest?

Category	Unit Testing	Unit Testing
General info	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.	MSTest is a Unit testing framework for the .net framework MSTest is fully integrated with Visual Studios and works natively without the need for any plugins. MSTest is better suited for only using Microsoft technologies rather than mixed technology environments.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Nunit is one of many programs in the xUnit family	Yes MsTest is an xUnit type framework
Client-side Allows testing code execution on the client, such as a web browser	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	Yes MsTest can test various front-end components
Server-side Allows testing the bahovior of a server-side code	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	Yes With MSTest you can test various back-end components individually
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes NUnit contains the fixture methods SetUp to initialize your test environment and TearDown method to destroy a test environment	Yes MSTest contains fixture methods TestInitialize to setup your environment and TestCleanup to destroy the 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.	Yes Group fixtures are available in NUnit	Yes Group fixtures are available
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 You can create mock objects using the third party library moq	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	Yes Grouping of tests into suites is possible with MSTest
