What are the differences between Unit.js and Ginkgo?

Unit.js

Ginkgo

http://onsi.github.io/ginkgo/
Programming language

JavaScript

Go

Category

Unit Testing, End-to-End Testing

Unit Testing, Intergration 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.

BDD testing framework for Go

Ginkgo is a BDD testing framework for Go that has a great matcher library to go with it called Gomega and intergrates with the standard testing library
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

Yes

Yes, by creating unit tests then testing individual front-end components
Server-side
Allows testing the bahovior of a server-side code

Yes

Unit.js runs in nodejs to test server-side behaviour

Yes

Yes by creating unit tests then testing various back-end components
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

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.

Yes

With Unit.js you can group your fixtures

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

They are available by running the command: 'ginko bootstrap'
Licence
Licence type governing the use and redistribution of the software

GNU

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

Dvelopers can generate mocks by using the third party package 'gomock'
Grouping
Allows organizing tests in groups

N/A

Yes

Ginkgo allows you to group tests in 'Describe' and 'Context' container blocks. It also provides 'It' and 'Specify' blocks to hold your assertions
