/*
|
|
* == 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.
|
|
*
|
|
* 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"
|
|
*
|
|
* flags - space separated list of test flags in addition to any present in
|
|
* the head metadata
|
|
*
|
|
* == 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.
|
|
*
|
|
* == 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
|
|
*
|
|
* 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).
|
|
*
|
|
* == 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_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

/*
|
|
* 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
|
|
*
