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

N/A

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

It can test front end components

Yes

Yes, since it is also easily hooked to 'testing' package it is used to test front-end components
Server-side
Allows testing the bahovior of a server-side code

Yes

It can test back-end behaviour

Yes

Yes it can also be used to test back-end components and functionality
Fixtures

Grouping
