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

Programming language	Java	Ruby
Category	Unit Testing	Unit Testing, Intergration Testing
General info	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	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	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.
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test your front-end code as individual components of code	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.
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side components and functionality with Cuppa.	Yes You can test server-side behaviour with Rspec
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Fixtures are available via the Setup and Teardown functions	Yes RSpec does contain fixture methods
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 You groups of tests can share these fixture methods	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.	N/A	Yes RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	MIT License
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)	N/A	Yes Available through rspec-mocks gem.
Grouping Allows organizing tests in groups	Yes This is a feature of cuppa, it allows you to group your tests together	Yes Allows declaring example groups and contexts.
