/**
* This file tests the CSS syntax highlighter in the MdnDocsWidget object.
*
* The CSS syntax highlighter accepts:
* - a string containing CSS
* - a DOM node
*
* It parses the string and creates a collection of DOM nodes for different
* CSS token types. These DOM nodes have CSS classes applied to them,
* to apply the right style for that particular token type. The DOM nodes
* are returned as children of the node that was passed to the function.
*
* This test code defines a number of different strings containing valid and
* invalid CSS in various forms. For each string it defines the DOM nodes
* that it expects to get from the syntax highlighter.
*
* It then calls the syntax highlighter, and checks that the resulting
* collection of DOM nodes is what we expected.
