MSTest vs XCTest comparison of testing frameworks
What are the differences between MSTest and XCTest?

	MSTest https://github.com/microsoft/testfx-docs	XCTest https://developer.apple.com/documentation/xctest
Programming language	.NET	Swift
Category	Unit Testing	Unit Testing, Performance 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.	XCTest is the default testing framework for unit tests, performance tests, and some level of UI tests for iOS apps. XCTest framework is a testing framework that enables developers write basic unit tests, performance tests, and some level of UI tests for iOS apps.
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 Yes, it is an xUnit style framework
Client-side Allows testing code execution on the client, such as a web browser	Yes MsTest can test various front-end components	Yes Developers can test individual front-end components with XCTest
Server-side Allows testing the bahovior of a server-side code	Yes With MSTest you can test various back-end components individually	Yes Yes, developers can test individual back-end components with XCTest
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	Yes XCTest contains setup() and teardown() fixture methods for setting up and destroying test environments
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	Yes Group fixtures are available in XCTest
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 protocol mocks and class mocks with libraries such as MockFive or Cuckoo
Grouping Allows organizing tests in groups	Yes Grouping of tests into suites is possible with MSTest	Yes Developers can define test suites from the XCTestSuite class
