RSpec vs Cuppa comparison of testing frameworks
What are the differences between RSpec and Cuppa?

	RSpec https://rspec.info	Cuppa http://cuppa.forgerock.org/
Programming language	Ruby	Java
Category	Unit Testing, Intergration Testing	Unit Testing
General info	Domain Specific Language (DSL) testing solution for Ruby code It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks.	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 Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification.	No
Client-side Allows testing code execution on the client, such as a web browser	Yes RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that.	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 You can test server-side behaviour with Rspec	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	Yes RSpec does contain fixture methods	Yes Fixtures are available via the Setup and Teardown functions
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	Yes You groups of tests can share these fixture methods
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.	Yes RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	Apache License 2.0
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 Available through rspec-mocks gem.	N/A
Grouping Allows organizing tests in groups	Yes Allows declaring example groups and contexts.	Yes This is a feature of cuppa, it allows you to group your tests together
