N/A

Yes

xUnit.net is part of the xUnit family of frameworks
Client-side
Allows testing code execution on the client, such as a web browser

Yes

Yes

You can test various front-end components independently since it is a Unit testing framework
Server-side
Allows testing the bahovior of a server-side code

Yes

Unexpected is used in a Node.JS environment to test server behaviour and functionality

Yes

You can test various back-end components independently since it is a Unit testing framework
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

Yes

It contains class fixtures which are setup once pertest class
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.

N/A

Yes

xUnit.net contains collection fixtures which allow you to share context among many tests
