+ * This file tests the MdnDocsWidget object, and specifically its
+ * loadCssDocs() function.
+ *
+ * The MdnDocsWidget is initialized with a document which has a specific
+ * structure. You then call loadCssDocs(), passing in a CSS property name.
+ * MdnDocsWidget then fetches docs for that property by making an XHR to
+ * a docs page, and loads the results into the document.
+ *
+ * In this file we test that the tooltip can properly handle the different
+ * structures that the docs page might have, including variant structures and
+ * error conditions like parts of the document being missing.
+ *
+ * We also test that the tooltip properly handles the case where the page
+ * doesn't exist at all.
