General info

Chai is a BDD / TDD assertion library for Node.js and the browser that can be paired with any JavaScript testing framework.

Chai is an assertion library, similar to Node's built-in assert and makes testing easier by giving you many assertions you can run against your code. It also includes a robust Plugin architecture for extending Chai's assertions and interfaces.

Enhance PHP is a lightweight Open Source PHP unit testing framework

It has support for mocks and stubs and runs in the browser, or via the command line
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

Yes

It tests front-end functionality and can run in the browser
Server-side
Allows testing the bahovior of a server-side code

Yes
