What are the differences between Unit.js and Spinach?

	Unit.js https://unitjs.com/	Spinach https://github.com/codegram/spinach
Programming language	JavaScript	Ruby
Category	Unit Testing, End-to-End Testing	Acceptance Testing
General info	An assertion library for JavaScript (similar to chai.js) It works with any test runner and unit testing framework like Mocha, Jasmine, Karma, protractor (E2E test framework for Angular apps) and QUnit.	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.		No
Client-side Allows testing code execution on the client, such as a web browser	Yes Unit.js runs in the browser to test front-end components	N/A
Server-side Allows testing the bahovior of a server-side code	Yes Unit.js runs in nodejs to test server-side behaviour	Yes You can test any server-side behaviour with Spinach
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Unit.js provides Test fixtures for running testsThis is one of its features	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 With Unit.js you can group your 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.		Yes Spinach has inbuilt generator methods

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 Spinach can access the rspec-mocks methods
Grouping Allows organizing tests in groups	N/A	Yes Spinach Integrates with your RSpec test suite which allows declaring example groups and contexts.
