-/*
- * == Introduction ==
- *
- * This file provides a framework for writing testcases. It is intended to
- * provide a convenient API for making common assertions, and to work both
- * for testing synchronous and asynchronous DOM features in a way that
- * promotes clear, robust, tests.
- *
- * == Basic Usage ==
- *
- * To use this file, import the script and the testharnessreport script into
- * the test document:
- * <script src=""
- * <script src=""
- *
- * Within each file one may define one or more tests. Each test is atomic
- * in the sense that a single test has a single result (pass/fail/timeout).
- * Within each test one may have a number of asserts. The test fails at the
- * first failing assert, and the remainder of the test is (typically) not run.
- *
- * If the file containing the tests is a HTML file with an element of id "log"
- * this will be populated with a table containing the test results after all
- * the tests have run.
- *
- * NOTE: By default tests must be created before the load event fires. For ways
- * to create tests after the load event, see "Determining when all tests
- * are complete", below
- *
- * == Synchronous Tests ==
- *
- * To create a synchronous test use the test() function:
- *
- * test(test_function, name, properties)
- *
- * test_function is a function that contains the code to test. For example a
- * trivial passing test would be:
- *
- * test(function() {assert_true(true)}, "assert_true with true")
- *
- * The function passed in is run in the test() call.
- *
- * properties is an object that overrides default test properties. The
- * recognised properties are:
- * timeout - the test timeout in ms
- *
- * e.g.
- * test(test_function, "Sample test", {timeout:1000})
- *
- * would run test_function with a timeout of 1s.
- *
- * Additionally, test-specific metadata can be passed in the properties. These
- * are used when the individual test has different metadata from that stored
- * in the <head>.
- * The recognized metadata properties are:
- *
- * help - The url of the part of the specification being tested
- *
- * assert - A human readable description of what the test is attempting
- * to prove
- *
- * author - Name and contact information for the author of the test in the
- * format: "Name <email_addr>" or "Name http://contact/url"
- *
- * == Asynchronous Tests ==
- *
- * Testing asynchronous features is somewhat more complex since the result of
- * a test may depend on one or more events or other callbacks. The API provided
- * for testing these features is indended to be rather low-level but hopefully
- * applicable to many situations.
- *
- * To create a test, one starts by getting a Test object using async_test:
- *
- * async_test(name, properties)
- *
- * e.g.
- * var t = async_test("Simple async test")
- *
- * Assertions can be added to the test by calling the step method of the test
- * object with a function containing the test assertions:
- *
- * t.step(function() {assert_true(true)});
- *
- * When all the steps are complete, the done() method must be called:
- *
- * t.done();
- *
- * As a convenience, async_test can also takes a function as first argument.
- * This function is called with the test object as both its `this` object and
- * first argument. The above example can be rewritten as:
- *
- * async_test(function(t) {
- * object.some_event = function() {
- * t.step(function (){assert_true(true); t.done();});
- * };
- * }, "Simple async test");
- *
- * which avoids cluttering the global scope with references to async
- * tests instances.
- *
- * The properties argument is identical to that for test().
- *
- * In many cases it is convenient to run a step in response to an event or a
- * callback. A convenient method of doing this is through the step_func method
- * which returns a function that, when called runs a test step. For example
- *
- * object.some_event = t.step_func(function(e) {assert_true(e.a)});
- *
- * == Making assertions ==
- *
- * Functions for making assertions start assert_
- * The best way to get a list is to look in this file for functions names
- * matching that pattern. The general signature is
- *
- * assert_something(actual, expected, description)
- *
- * although not all assertions precisely match this pattern e.g. assert_true
- * only takes actual and description as arguments.
- *
- * The description parameter is used to present more useful error messages when
- * a test fails
- *
- * NOTE: All asserts must be located in a test() or a step of an async_test().
- * asserts outside these places won't be detected correctly by the harness
- * and may cause a file to stop testing.
- *
- * == Harness Timeout ==
- *
- * The overall harness admits two timeout values "normal" (the
- * default) and "long", used for tests which have an unusually long
- * runtime. After the timeout is reached, the harness will stop
- * waiting for further async tests to complete. By default the
- * timeouts are set to 10s and 60s, respectively, but may be changed
- * when the test is run on hardware with different performance
- * characteristics to a common desktop computer. In order to opt-in
- * to the longer test timeout, the test must specify a meta element:
- * <meta name="timeout" content="long">
- *
- * == Setup ==
- *
- * Sometimes tests require non-trivial setup that may fail. For this purpose
- * there is a setup() function, that may be called with one or two arguments.
- * The two argument version is:
- *
- * setup(func, properties)
- *
- * The one argument versions may omit either argument.
- * func is a function to be run synchronously. setup() becomes a no-op once
- * any tests have returned results. Properties are global properties of the test
- * harness. Currently recognised properties are:
- *
- *
- * explicit_done - Wait for an explicit call to done() before declaring all
- * tests complete (see below)
- *
- * output_document - The document to which results should be logged. By default
- * this is the current document but could be an ancestor
- * document in some cases e.g. a SVG test loaded in an HTML
- * wrapper
- *
- * explicit_timeout - disable file timeout; only stop waiting for results
- * when the timeout() function is called (typically for
- * use when integrating with some existing test framework
- * that has its own timeout mechanism).
- *
- * allow_uncaught_exception - don't treat an uncaught exception as an error;
- * needed when e.g. testing the window.onerror
- * handler.
- *
- * timeout_multiplier - Multiplier to apply to per-test timeouts.
- *
- * == Determining when all tests are complete ==
- *
- * By default the test harness will assume there are no more results to come
- * when:
- * 1) There are no Test objects that have been created but not completed
- * 2) The load event on the document has fired
- *
- * This behaviour can be overridden by setting the explicit_done property to
- * true in a call to setup(). If explicit_done is true, the test harness will
- * not assume it is done until the global done() function is called. Once done()
- * is called, the two conditions above apply like normal.
- *
- * == Generating tests ==
- *
- * NOTE: this functionality may be removed
- *
- * There are scenarios in which is is desirable to create a large number of
- * (synchronous) tests that are internally similar but vary in the parameters
- * used. To make this easier, the generate_tests function allows a single
- * function to be called with each set of parameters in a list:
- *
- * generate_tests(test_function, parameter_lists, properties)
- *
- * For example:
- *
- * generate_tests(assert_equals, [
- * ["Sum one and one", 1+1, 2],
- * ["Sum one and zero", 1+0, 1]
- * ])
- *
- * Is equivalent to:
- *
- * test(function() {assert_equals(1+1, 2)}, "Sum one and one")
- * test(function() {assert_equals(1+0, 1)}, "Sum one and zero")
- *
- * Note that the first item in each parameter list corresponds to the name of
- * the test.
- *
- * The properties argument is identical to that for test(). This may be a
- * single object (used for all generated tests) or an array.
- *
- * == Callback API ==
- *
- * The framework provides callbacks corresponding to 3 events:
- *
- * start - happens when the first Test is created
- * result - happens when a test result is recieved
- * complete - happens when all results are recieved
- *
- * The page defining the tests may add callbacks for these events by calling
- * the following methods:
- *
- * add_start_callback(callback) - callback called with no arguments
- * add_result_callback(callback) - callback called with a test argument
- * add_completion_callback(callback) - callback called with an array of tests
- * and an status object
- *
- * tests have the following properties:
- * status: A status code. This can be compared to the PASS, FAIL, TIMEOUT and
- * NOTRUN properties on the test object
- * message: A message indicating the reason for failure. In the future this
- * will always be a string
- *
- * The status object gives the overall status of the harness. It has the
- * following properties:
- * status: Can be compared to the OK, ERROR and TIMEOUT properties
- * message: An error message set when the status is ERROR
- *
- * == External API ==
- *
- * In order to collect the results of multiple pages containing tests, the test
- * harness will, when loaded in a nested browsing context, attempt to call
- * certain functions in each ancestor and opener browsing context:
- *
- * start - start_callback
- * result - result_callback
- * complete - completion_callback
- *
- * These are given the same arguments as the corresponding internal callbacks
- * described above.
- *
- * == External API through cross-document messaging ==
- *
- * Where supported, the test harness will also send messages using
- * cross-document messaging to each ancestor and opener browsing context. Since
- * it uses the wildcard keyword (*), cross-origin communication is enabled and
- * script on different origins can collect the results.
- *
- * This API follows similar conventions as those described above only slightly
- * modified to accommodate message event API. Each message is sent by the harness
- * is passed a single vanilla object, available as the `data` property of the
- * event object. These objects are structures as follows:
- *
- * start - { type: "start" }
- * result - { type: "result", test: Test }
- * complete - { type: "complete", tests: [Test, ...], status: TestsStatus }
- *
- * == List of assertions ==
- *
- * assert_true(actual, description)
- * asserts that /actual/ is strictly true
- *
- * assert_false(actual, description)
- * asserts that /actual/ is strictly false
- *
- * assert_equals(actual, expected, description)
- * asserts that /actual/ is the same value as /expected/
- *
- * assert_not_equals(actual, expected, description)
- * asserts that /actual/ is a different value to /expected/. Yes, this means
- * that "expected" is a misnomer
- *
- * assert_in_array(actual, expected, description)
- * asserts that /expected/ is an Array, and /actual/ is equal to one of the
- * members -- expected.indexOf(actual) != -1
- *
- * assert_array_equals(actual, expected, description)
- * asserts that /actual/ and /expected/ have the same length and the value of
- * each indexed property in /actual/ is the strictly equal to the corresponding
- * property value in /expected/
- *
- * assert_approx_equals(actual, expected, epsilon, description)
- * asserts that /actual/ is a number within +/- /epsilon/ of /expected/
- *
- * assert_less_than(actual, expected, description)
- * asserts that /actual/ is a number less than /expected/
- *
- * assert_greater_than(actual, expected, description)
- * asserts that /actual/ is a number greater than /expected/
- *
- * assert_less_than_equal(actual, expected, description)
- * asserts that /actual/ is a number less than or equal to /expected/
- *
- * assert_greater_than_equal(actual, expected, description)
- * asserts that /actual/ is a number greater than or equal to /expected/
- *
- * assert_regexp_match(actual, expected, description)
- * asserts that /actual/ matches the regexp /expected/
- *
- * assert_class_string(object, class_name, description)
- * asserts that the class string of /object/ as returned in
- * Object.prototype.toString is equal to /class_name/.
- *
- * assert_own_property(object, property_name, description)
- * assert that object has own property property_name
- *
- * assert_inherits(object, property_name, description)
- * assert that object does not have an own property named property_name
- * but that property_name is present in the prototype chain for object
- *
- * assert_idl_attribute(object, attribute_name, description)
- * assert that an object that is an instance of some interface has the
- * attribute attribute_name following the conditions specified by WebIDL
- *
- * assert_readonly(object, property_name, description)
- * assert that property property_name on object is readonly
- *
- * assert_throws(code, func, description)
- * code - the expected exception:
- * o string: the thrown exception must be a DOMException with the given
- * name, e.g., "TimeoutError" (for compatibility with existing
- * tests, a constant is also supported, e.g., "TIMEOUT_ERR")
- * o object: the thrown exception must have a property called "name" that
- * matches code.name
- * o null: allow any exception (in general, one of the options above
- * should be used)
- * func - a function that should throw
- *
- * assert_unreached(description)
- * asserts if called. Used to ensure that some codepath is *not* taken e.g.
- * an event does not fire.
- *
- * assert_any(assert_func, actual, expected_array, extra_arg_1, ... extra_arg_N)
- * asserts that one assert_func(actual, expected_array_N, extra_arg1, ..., extra_arg_N)
- * is true for some expected_array_N in expected_array. This only works for assert_func
- * with signature assert_func(actual, expected, args_1, ..., args_N). Note that tests
- * with multiple allowed pass conditions are bad practice unless the spec specifically
- * allows multiple behaviours. Test authors should not use this method simply to hide
- * UA bugs.
- *
- * assert_exists(object, property_name, description)
- * *** deprecated ***
- * asserts that object has an own property property_name
- *
- * assert_not_exists(object, property_name, description)
- * *** deprecated ***
- * assert that object does not have own property property_name
