General info

tap-producing test harness for node and browsers.

Tape API is a small superset of the node core assert module

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

Yes

It does support xUnit output

Yes

test-unit is a xUnit family unit testing framework for Ruby
Client-side
Allows testing code execution on the client, such as a web browser

Yes

You can write tests for any part of your front-end code to test any component or functionality

It could have tested some front-end components but its now legacy hence wouldn't work with the many new front-end components
Server-side
Allows testing the bahovior of a server-side code

Yes

With tape you can test any back-end component, behaviour and functionality after all it supports TAP (Test Anything Protocol)

Yes

Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

No

Tape contains only the essential features for making assertions on your code but there is a package called redtape that extends tape to give you beforeEach and afterEach functionality

Yes

Fixture methods are available through its ClassMethods Module
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.

No

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

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

Tape is a minimalistic framework that provides only essential features to make your assertions about your code

No

Grouping
Allows organizing tests in groups

No

Tape contains only the essential features for making assertions on your code

No
