* exclude: An array of contexts to exclude from testing. The valid values are:
* ["document", "element", "fragment", "detached", "html", "xhtml"]
* The "html" and "xhtml" values represent the type of document being queried. These are useful
* for tests that are affected by differences between HTML and XML, such as case sensitivity.
*
* 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.
