| /* | |
| * == 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="/resources/testharness.js"></script> | |
| * <script src="/resources/testharnessreport.js"></script> | |
| * | |
| * 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. | |
| * | |
| * == 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(); | |
| * | |
| * 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. | |
| * | |
| * == 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: | |
| * | |
| * timeout - The time in ms after which the harness should stop waiting for | |
| * tests to complete (this is different to the per-test timeout | |
| * because async tests do not start their timer until .step is called) | |
| * | |
| * 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 | |
| * | |
| * == 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) | |
| * | |
| * 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. | |
| * | |
| * == 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 browsing context: | |
| * | |
| * start - start_callback | |
| * result - result_callback | |
| * complete - completion_callback | |
| * | |
| * These are given the same arguments as the corresponding internal callbacks | |
| * described above. | |
| * | |
| * == 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_regexp_match(actual, expected, description) | |
| * asserts that /actual/ matches the regexp /expected/ | |
| * | |
| * 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 - a DOMException/RangeException code as a string, e.g. "HIERARCHY_REQUEST_ERR" | |
| * func - a function that should throw | |
| * | |
| * assert that func throws a DOMException or RangeException (as appropriate) | |
| * with the given code. If an object is passed for code instead of a string, | |
| * checks that the thrown exception has a property called "name" that matches | |
| * the property of code called "name". Note, this function will probably be | |
| * rewritten sometime to make more sense. | |
| * | |
| * assert_unreached(description) | |
| * asserts if called. Used to ensure that some codepath is *not* taken e.g. | |
| * an event does not fire. | |
| * | |
| * 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 | |

| * 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 | |
| * | |
