General info

Complete suite of testing facilities

Minitest is small, fast, and it aims to make tests clean and readable. It supports test-driven development (TDD), behavior-driven development (BDD), mocking, and benchmarking.

JDave is a BDD framework for Java

JDave is inspired by RSpec and integrates JMock 2 as mocking framework and Hamcrest as matching library. It uses JUnit adapter to launch JDave specifications. This way it is possible to have IDE, build tool and coverage tool support from day one.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

MiniTest is an xUnit style framework in that is has assertion functions in the style of xUnit/TDD

No

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

No

Yes

Front-end behaviour can be tested with JDave
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test various back-end components

Yes

JDave can test 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

Minitest supports test fixture functions

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

Minitest has group fixtures

N/A

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.

N/A

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)

Yes

Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework

Yes

It integrates JMock 2 as mocking framework
Grouping
Allows organizing tests in groups

Yes

Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem

Yes

Specifications can be grouped by tagging them with @Group annotation.
