xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

Server-side
Allows testing the bahovior of a server-side code

Yes

With MSTest you can test various back-end components individually

Yes

You can test any server-side behaviour with Spinach
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

No

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 create mock objects using the third party library moq

Yes

Spinach can access the rspec-mocks methods
Grouping
Allows organizing tests in groups

Yes

Grouping of tests into suites is possible with MSTest

Yes
