What are the differences between Spinach and testdouble.js?

	Spinach https://github.com/codegram/spinach	testdouble.js https://github.com/testdouble/testdouble.js
Programming language	Ruby	JavaScript
Category	Acceptance Testing	Unit Testing, Intergration Testing
General info	Spinach is a BDD framework on top of Gherkin Spinach is a high-level BDD framework that leverages the Gherkin language to help define executable specifications of your application or library's acceptance criteria.	This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development) Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It is compatible with xUnit and supportsxUnit XML output
Client-side Allows testing code execution on the client, such as a web browser	N/A	No
Server-side Allows testing the bahovior of a server-side code	Yes You can test any server-side behaviour with Spinach	Yes Testdouble is primarily used to test server-side functions, behaviours and components
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	N/A
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 Spinach has inbuilt generator methods
Licence Licence type governing the use and redistribution of the software	MIT License	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 Spinach can access the rspec-mocks methods	Yes Testdouble includes inbuilt support for mocking
Grouping Allows organizing tests in groups	Yes Spinach Integrates with your RSpec test suite which allows declaring example groups and contexts.	N/A
