+ *   level:     An integer indicating the CSS or Selectors level in which the selector being tested was introduced.
+ *
+ *   testType:  A bit-mapped flag indicating the type of test.
+ *
+ * The test function for these tests accepts a specified root node, on which the methods will be invoked during the tests.
+ *
+ * Based on whether either 'context' or 'refNodes', or both, are specified the tests will execute the following methods:
+ *
+ * Where testType is TEST_FIND:
+ *
+ * context.findAll(selector, refNodes)
+ * context.findAll(selector)        // Only if refNodes is not specified
+ * root.findAll(selector, context)  // Only if refNodes is not specified
+ * root.findAll(selector, refNodes) // Only if context is not specified
+ * root.findAll(selector)           // Only if neither context nor refNodes is specified
+ *
+ * Where testType is TEST_QSA
+ *
+ * context.querySelectorAll(selector)
+ * root.querySelectorAll(selector)  // Only if neither context nor refNodes is specified
+ *
+ * Equivalent tests will be run for .find() as well.
+ * Note: Do not specify a testType of TEST_QSA where either implied :scope or explicit refNodes
+ * are required.
+ *
+ * Where testType is TEST_MATCH:
+ * For each expected result given, within the specified root:
+ *
+ * expect.matches(selector, context)    // Only where refNodes is not specified
+ * expect.matches(selector, refNodes)
+ * expect.matches(selector)             // Only if neither context nor refNodes is specified
+ *
+ * The tests involving refNodes for both find(), findAll() and matches() will each be run by passing the
+ * collection as a NodeList, an Array and, if there is only a single element, an Element node.
+ *
+ * Note: Interactive pseudo-classes (:active :hover and :focus) have not been tested in this test suite.
