* 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

/*
* These selectors are intended to be used with the find(), findAll() and matches() methods. Expected results
* should be determined under the assumption that :scope will be prepended to the selector where appropriate,
* in accordance with the specification.
*
* All of these should be valid relative selectors, expected to match zero or more elements in the document.
* None should throw any errors.
*
* name: A descriptive name of the selector being tested
*
* selector: The selector to test
*
* ctx: A selector to obtain the context object to use for tests invoking context.find(),
* and to use as a single reference node for tests invoking document.find().
* Note: context = root.querySelector(ctx);
*
* ref: A selector to obtain the reference nodes to be used for the selector.
* Note: If root is the document or an in-document element:
* refNodes = document.querySelectorAll(ref);
* Otherwise, if root is a fragment or detached element:
* refNodes = root.querySelectorAll(ref);
*
* expect: A list of IDs of the elements expected to be matched. List must be given in tree order.
*
* unexpected: A list of IDs of some elements that are not expected to match the given selector.
* This is used to verify that unexpected.matches(selector, refNode) does not match.
*
* 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.
