   * This test suite tests Selectors API methods in 4 different contexts:
   * 1. Document node
   * 2. In-document Element node
   * 3. Detached Element node (an element with no parent, not in the document)
   * 4. Document Fragment node
   *
   * For each context, the following tests are run:
   *
   * The interface check tests ensure that each type of node exposes the Selectors API methods
   *
   * The special selector tests verify the result of passing special values for the selector parameter,
   * to ensure that the correct WebIDL processing is performed, such as stringification of null and
   * undefined and missing parameter. The universal selector is also tested here, rather than with the
   * rest of ordinary selectors for practical reasons.
   *
   * The static list verification tests ensure that the node lists returned by the method remain unchanged
   * due to subsequent document modication, and that a new list is generated each time the method is
   * invoked based on the current state of the document.
   *
   * The invalid selector tests ensure that SyntaxError is thrown for invalid forms of selectors
   *
   * The valid selector tests check the result from querying many different types of selectors, with a
   * list of expected elements. This checks that querySelector() always returns the first result from
   * querySelectorAll(), and that all matching elements are correctly returned in tree-order. The tests
   * can be limited by specifying the test types to run, using the testType variable. The constants for this
   * can be found in selectors.js.
   *
   * All the selectors tested for both the valid and invalid selector tests are found in selectors.js.
   * See comments in that file for documentation of the format used.
   *
   * The ParentNode-querySelector-All.js file contains all the common test functions for running each of the aforementioned tests
