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

	Turnip https://github.com/jnicklas/turnip	Concordion https://concordion.org/
Programming language	Ruby	Java
Category	Acceptance Testing, Integration Testing
General info	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.	Concordion is a tool used to write and manage automated acceptance tests in Java based projects Concordion specifications are written in Markdown, HTML or Excel and then instrumented with special links, attributes or comments respectively. When the corresponding test fixture class is run, Concordion interprets the instrumentation to execute the test. Concordion lets you write them in normal language using paragraphs, tables and proper punctuation. This makes specification more natural to read and write, and helps everyone to understand and agree about what a feature is supposed to do.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Turnip can perform end-to-end tests therefore test front-end components and functionality	Yes You can specify tests for front-end components and functionality with concordion
Server-side Allows testing the bahovior of a server-side code	Yes Turnip is used to test server-side behaviour and components	Yes You can test server-side components and functionality with concordion.
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No	Yes Concordion contains fixtures which correspond to a specific instrumentation within the code. That is when specifications are written they are instrumented with special links, attributes or comments which are then run with their corresponding fixtures
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.	No	Yes One can group fixtures in concordion
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.	No	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 By intergrating with RSpec turnip has access to the rspec-mocks gem	Yes By use of third party libraries like mockito
Grouping Allows organizing tests in groups	Yes Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.	Yes One can group tests into suites
