-/*
- * 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.

-     * Convert a value to a nice, human-readable string
-     *
-     * When many JavaScript Object values are coerced to a String, the

-     * helpful information, making the coerced value unsuitable for
-     * use in assertion messages, test names, and debugging
-     * statements. `format_value` produces more distinctive string
-     * representations of many kinds of objects, including arrays and
-     * the more important DOM Node types. It also translates String
-     * values containing control characters to include human-readable
-     * representations.
-     *
-     * @example
-     * // "Document node with 2 children"
-     * format_value(document);
-     * @example
-     * // "\"foo\\uffffbar\""
-     * format_value("foo\uffffbar");
-     * @example
-     * // "[-0, Infinity]"
-     * format_value([-0, Infinity]);
-     * @param {Any} val - The value to convert to a string.
-     * @returns {string} - A string representation of ``val``, optimised for human readability.

-     * Assert a DOMException with the expected type is thrown.

-     * There are two ways of calling assert_throws_dom:
-     *
-     * 1) If the DOMException is expected to come from the current global, the
-     * second argument should be the function expected to throw and a third,
-     * optional, argument is the assertion description.
-     *
-     * 2) If the DOMException is expected to come from some other global, the
-     * second argument should be the DOMException constructor from that global,
-     * the third argument the function expected to throw, and the fourth, optional,
-     * argument the assertion description.
-     *
-     * @param {number|string} type - The expected exception name or
-     * code.  See the `table of names and codes
-     * `_. If a
-     * number is passed it should be one of the numeric code values in
-     * that table (e.g. 3, 4, etc).  If a string is passed it can
-     * either be an exception name (e.g. "HierarchyRequestError",
-     * "WrongDocumentError") or the name of the corresponding error
-     * code (e.g. "``HIERARCHY_REQUEST_ERR``", "``WRONG_DOCUMENT_ERR``").
-     * @param {Function} descriptionOrFunc - The function expected to
-     * throw (if the exception comes from another global), or the
-     * optional description of the condition being tested (if the
-     * exception comes from the current global).

-     * Template code
-     *
-     * A template is just a JavaScript structure. An element is represented as:
-     *
-     * [tag_name, {attr_name:attr_value}, child1, child2]
-     *
-     * the children can either be strings (which act like text nodes), other templates or
-     * functions (see below)
-     *
-     * A text node is represented as
-     *
-     * ["{text}", value]
-     *
-     * String values have a simple substitution syntax; ${foo} represents a variable foo.
-     *
-     * It is possible to embed logic in templates by using a function in a place where a
-     * node would usually go. The function must either return part of a template or null.
-     *
-     * In cases where a set of nodes are required as output rather than a single node
-     * with children it is possible to just use a list
-     * [node1, node2, node3]
-     *
-     * Usage:
-     *
-     * render(template, substitutions) - take a template and an object mapping
-     * variable names to parameters and return either a DOM node or a list of DOM nodes
-     *
-     * substitute(template, substitutions) - take a template and variable mapping object,
-     * make the variable substitutions and return the substituted template
-     *
