General info

Elixir library for browser automation and writing intergration tests

It is a front-end testing library that has support for: Selenium (Firefox, Chrome), ChromeDriver and PhantomJs. Also supports JavaScript applications and retries tests a few times before reporting errors

An assertion library for JavaScript (similar to chai.js)

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

Allows for browser Automation and writing of end-to-end tests for web apps, supports Selenium WebDriver, ChromeDriver, and PhantomJS - GhostDriver

Yes

Unit.js runs in the browser to test front-end components
Server-side
Allows testing the bahovior of a server-side code

N/A

Yes

Unit.js runs in nodejs to test 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

N/A

Yes

Unit.js provides Test fixtures for running testsThis is one of its features
Group fixtures

Not inbuilt but by use of a third party library like ExopData
