xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes Yes, it is a xUnit style framework
Client-side Allows testing code execution on the client, such as a web browser	Yes Front-end components can be tested; there is also espec_phoenix for the Phoenix web framework	Yes QUnit is commonly used by jQuery, jQuery UI and jQuery Mobile It can test front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes databases and server behaviour can be tested using Espec	Yes Qunit can test any JavaScript code(including itself), this includes server-side components and functionality. Supports NodeJs
