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

	Arquillian http://arquillian.org/	MSTest https://github.com/microsoft/testfx-docs
Programming language	Java	.NET
Category	Intergration Testing, Functional Testing	Unit Testing
General info	Arquillian is an Open source framework for writing Integration and functional tests Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well	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 It is a xUnit framework	Yes MsTest is an xUnit type framework
Client-side Allows testing code execution on the client, such as a web browser	Yes You can perform unit tests on front-end components and functionality	Yes MsTest can test various front-end components
Server-side Allows testing the bahovior of a server-side code	Yes You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions	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 By use of extensions, for example you can use the Persistence extension to set database fixtures	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 You can define group fixtures	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 Arquillian supports mock object functionality you can use third party libraries	Yes You can create mock objects using the third party library moq
Grouping Allows organizing tests in groups	Yes Arquilian supports grouping of tests	Yes Grouping of tests into suites is possible with MSTest
