Turnip vs Sinon.js comparison of testing frameworks
What are the differences between Turnip and Sinon.js?

	Turnip https://github.com/jnicklas/turnip	Sinon.js https://sinonjs.org/
Programming language	Ruby	JavaScript
Category	Acceptance Testing, Integration Testing	Unit 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.	Standalone test stubs and mocks for JavaScript. Works with any unit testing framework. Sinon.js is a great library when you want to unit test your code with supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes Compatible
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 Sinon.js is a good library for unit testing your front-end code and has cross browser support
Server-side Allows testing the bahovior of a server-side code	Yes Turnip is used to test server-side behaviour and components	Yes Sinon.js can run on node.js to test back-end components and server-side behaviour
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	No	N/A
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
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
Licence Licence type governing the use and redistribution of the software	MIT License	New BSD License; Modified BSD 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 By intergrating with RSpec turnip has access to the rspec-mocks gem	Yes SinonJS is basically a library that we can use to create object mocks for unit testing
Grouping Allows organizing tests in groups	Yes Turnip Integrates directly into your RSpec test suite which allows declaring example groups and contexts.
