Arquillian vs Turnip comparison of testing frameworks
What are the differences between Arquillian and Turnip?

	Arquillian http://arquillian.org/	Turnip https://github.com/jnicklas/turnip
Programming language	Java	Ruby
Category	Intergration Testing, Functional Testing	Acceptance Testing, Integration Testing
General info	Arquillian is an Open source framework for writing Integration and functional tests Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well	Turnip is a Gherkin extension for RSpec Turnip is an open source Ruby gem that provides a platform for acceptance tests.It combines Gherkin, a language defined by the Cucumber Behavior-Driven Development (BDD) tool to express requirements, and RSpec, an open source BDD tool for Ruby developers.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes It is a xUnit framework	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can perform unit tests on front-end components and functionality	Yes Turnip can perform end-to-end tests therefore test front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions	Yes Turnip is used to test server-side behaviour and components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes By use of extensions, for example you can use the Persistence extension to set database fixtures	No
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 can define group fixtures	No
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	No
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)	Yes Arquillian supports mock object functionality you can use third party libraries	Yes By intergrating with RSpec turnip has access to the rspec-mocks gem
Grouping Allows organizing tests in groups	Yes Arquilian supports grouping of tests	Yes Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.
