MSTest vs testdouble.js comparison of testing frameworks
What are the differences between MSTest and testdouble.js?

	MSTest https://github.com/microsoft/testfx-docs	testdouble.js https://github.com/testdouble/testdouble.js
Programming language	.NET	JavaScript
Category	Unit Testing	Unit Testing, Intergration Testing
General info	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.	This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development) Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes MsTest is an xUnit type framework	Yes It is compatible with xUnit and supportsxUnit XML output
Client-side Allows testing code execution on the client, such as a web browser	Yes MsTest can test various front-end components	No
Server-side Allows testing the bahovior of a server-side code	Yes With MSTest you can test various back-end components individually	Yes Testdouble is primarily used to test server-side functions, behaviours and components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes MSTest contains fixture methods TestInitialize to setup your environment and TestCleanup to destroy the test environment	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	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

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 Testdouble includes inbuilt support for mocking
Grouping Allows organizing tests in groups	Yes Grouping of tests into suites is possible with MSTest	N/A
