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

Turnip is a Gherkin extension for RSpec

Turnip is an open source Ruby gem that provides a platform for acceptance tests.It combines Gherkin, a language defined by the Cucumber Behavior-Driven Development (BDD) tool to express requirements, and RSpec, an open source BDD tool for Ruby developers.
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

Turnip can perform end-to-end tests therefore test front-end components and functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

Yes

Turnip is used to test server-side behaviour and components
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

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

Group fixture methods are supported

No

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

No

Licence
Licence type governing the use and redistribution of the software

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

By intergrating with RSpec turnip has access to the rspec-mocks gem
Grouping
Allows organizing tests in groups

No

Yes

Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.
