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.

Cuppa is a testing framework for Java 8+

Cuppa is a testing framework for Java 8+ that is descriptive that is; it uses strings,not identifiers , to clearly describe the behaviour you are testing it also allows you to Group tests together by creating a structure in your test files to reduce repetition and improve readability and also you Define tests at runtime
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

No

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

No

Yes

You can test your front-end code as individual components of code
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 test server-side components and functionality with Cuppa.
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

Fixtures are available via the Setup and Teardown functions
Group fixtures
