General info

This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development)

Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.

Jnario is a test framework for Java focusing on the design and documentation aspects of testing

Jnario is based on Xtend and consists of two domain-specific languages, one for writing readable acceptance tests, the other for succinct unit tests. Together they are well suited for behavior-driven development of Java programs.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

It is compatible with xUnit and supportsxUnit XML output

Yes

It is an xUnit type testing framework
Client-side
Allows testing code execution on the client, such as a web browser

No

Yes

You can write scenarios to test various front-end behaviours using 'Given', 'When', 'Then' steps to describe simple scenarios
Server-side
Allows testing the bahovior of a server-side code

Yes

Testdouble is primarily used to test server-side functions, behaviours and components

Yes

You can write unit tests to test server side behaviours and components using Jnario specs
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

Yes

It contains the Setup & Teardown functions similar to JUnit but less verbose
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.

N/A

Yes

The Setup & Teardown functions can be used as group fixtures.
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

Licence

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

Testdouble includes inbuilt support for mocking

Yes

You can implement mocking through the use of a third partylibrary like Mockito
Grouping
Allows organizing tests in groups

N/A

Yes

Jnario Suites allows you to group multiple specifications into suites and execute them together, you do this using the suite wizard
