General info

Test::Unit is a unit testing framework for Ruby

Test::Unit is an implementation of the xUnit testing framework for ruby which is used for Unit Testing. However Test::Unit has been left in the standard library to support legacy test suites therefore if you are writing new test code use Minitest instead of Test::Unit

Standalone test stubs and mocks for JavaScript. Works with any unit testing framework.

Sinon.js is a great library when you want to unit test your code with supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

test-unit is a xUnit family unit testing framework for Ruby

Yes

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

It could have tested some front-end components but its now legacy hence wouldn't work with the many new front-end components

Yes

Sinon.js is a good library for unit testing your front-end code and has cross browser support
Server-side
Allows testing the bahovior of a server-side code

Yes

Yes

Sinon.js can run on node.js to test back-end components and server-side behaviour
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Fixture methods are available through its ClassMethods Module

N/A

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 fixture methods are supported

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.

No

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)

No

Yes

SinonJS is basically a library that we can use to create object mocks for unit testing
Grouping
Allows organizing tests in groups

No
