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

Cucumber-JVM is a pure Java implementation of Cucumber

The specifications are written in plain texts, which allows them to be easily understandable by all stakeholders.
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

No

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

You can test the front-end part like the GUI using cucumber with serenity, they integrate well to test your front-end.
Server-side
Allows testing the bahovior of a server-side code

Yes

Yes

You can test back-end components such as API's using rest&soap clients, and databases
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

Yes

Using the cucumber extension aruba you can create fixures in two steps: 1.Create a fixtures-directory; 2.Create fixture files in this directory
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

Yes

You can group your fixtures inside your fixtures directories
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
