|
| - * == 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

| + * <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
