|
|
|
- * This file automatically generates browser tests for WebIDL interfaces, using
|
|
|
- * the testharness.js framework. To use, first include the following:
|
|
|
- *
|
|
|
- * <script src=/resources/testharness.js></script>
|
|
|
- * <script src=/resources/testharnessreport.js></script>
|
|
|
- * <script src=/resources/webidl2.js></script>
|
|
|
- * <script src=/resources/idlharness.js></script>
|
|
|
- *
|
|
|
- * Then you'll need some type of IDLs. Here's some script that can be run on a
|
|
|
- * spec written in HTML, which will grab all the elements with class="idl",
|
|
|
- * concatenate them, and replace the body so you can copy-paste:
|
|
|
- *
|
|
|
- var s = "";
|
|
|
- [].forEach.call(document.getElementsByClassName("idl"), function(idl) {
|
|
|
- //https://www.w3.org/Bugs/Public/show_bug.cgi?id=14914
|
|
|
- if (!idl.classList.contains("extract"))
|
|
|
- {
|
|
|
- s += idl.textContent + "\n\n";
|
|
|
- }
|
|
|
- });
|
|
|
- document.body.innerHTML = '<pre></pre>';
|
|
|
- document.body.firstChild.textContent = s;
|
|
|
- *
|
|
|
- * (TODO: write this in Python or something so that it can be done from the
|
|
|
- * command line instead.)
|
|
|
- *
|
|
|
- * Once you have that, put it in your script somehow. The easiest way is to
|
|
|
- * embed it literally in an HTML file with <script type=text/plain> or similar,
|
|
|
- * so that you don't have to do any escaping. Another possibility is to put it
|
|
|
- * in a separate .idl file that's fetched via XHR or similar. Sample usage:
|
|
|
- *
|
|
|
- * var idl_array = new IdlArray();
|
|
|
- * idl_array.add_untested_idls("interface Node { readonly attribute DOMString nodeName; };");
|
|
|
- * idl_array.add_idls("interface Document : Node { readonly attribute DOMString URL; };");
|
|
|
- * idl_array.add_objects({Document: ["document"]});
|
|
|
- * idl_array.test();
|
|
|
- *
|
|
|
- * This tests that window.Document exists and meets all the requirements of
|
|
|
- * WebIDL. It also tests that window.document (the result of evaluating the
|
|
|
- * string "document") has URL and nodeName properties that behave as they
|
|
|
- * should, and otherwise meets WebIDL's requirements for an object whose
|
|
|
- * primary interface is Document. It does not test that window.Node exists,
|
|
|
- * which is what you want if the Node interface is already tested in some other
|
|
|
- * specification's suite and your specification only extends or refers to it.
|
|
|
- * Of course, each IDL string can define many different things, and calls to
|
|
|
- * add_objects() can register many different objects for different interfaces:
|
|
|
- * this is a very simple example.
|
|
|
- *
|
|
|
- * TODO: Write assert_writable, assert_enumerable, assert_configurable and
|
|
|
- * their inverses, and use those instead of just checking
|
|
|
- * getOwnPropertyDescriptor.
|
|
|
- *
|
|
|
- * == Public methods of IdlArray ==
|
|
|
- *
|
|
|
- * IdlArray objects can be obtained with new IdlArray(). Anything not
|
|
|
- * documented in this section should be considered an implementation detail,
|
|
|
- * and outside callers should not use it.
|
|
|
- *
|
|
|
- * add_idls(idl_string):
|
|
|
- * Parses idl_string (throwing on parse error) and adds the results to the
|
|
|
- * IdlArray. All the definitions will be tested when you run test(). If
|
|
|
- * some of the definitions refer to other definitions, those must be present
|
|
|
- * too. For instance, if idl_string says that Document inherits from Node,
|
|
|
- * the Node interface must also have been provided in some call to add_idls()
|
|
|
- * or add_untested_idls().
|
|
|
- *
|
|
|
- * add_untested_idls(idl_string):
|
|
|
- * Like add_idls(), but the definitions will not be tested. If an untested
|
|
|
- * interface is added and then extended with a tested partial interface, the
|
|
|
- * members of the partial interface will still be tested. Also, all the
|
|
|
- * members will still be tested for objects added with add_objects(), because
|
|
|
- * you probably want to test that (for instance) window.document has all the
|
|
|
- * properties from Node, not just Document, even if the Node interface itself
|
|
|
- * is tested in a different test suite.
|
|
|
- *
|
|
|
- * add_objects(dict):
|
|
|
- * dict should be an object whose keys are the names of interfaces or
|
|
|
- * exceptions, and whose values are arrays of strings. When an interface or
|
|
|
- * exception is tested, every string registered for it with add_objects()
|
|
|
- * will be evaluated, and tests will be run on the result to verify that it
|
|
|
- * correctly implements that interface or exception. This is the only way to
|
|
|
- * test anything about [NoInterfaceObject] interfaces, and there are many
|
|
|
- * tests that can't be run on any interface without an object to fiddle with.
|
|
|
- *
|
|
|
- * The interface has to be the *primary* interface of all the objects
|
|
|
- * provided. For example, don't pass {Node: ["document"]}, but rather
|
|
|
- * {Document: ["document"]}. Assuming the Document interface was declared to
|
|
|
- * inherit from Node, this will automatically test that document implements
|
|
|
- * the Node interface too.
|
|
|
- *
|
|
|
- * Warning: methods will be called on any provided objects, in a manner that
|
|
|
- * WebIDL requires be safe. For instance, if a method has mandatory
|
|
|
- * arguments, the test suite will try calling it with too few arguments to
|
|
|
- * see if it throws an exception. If an implementation incorrectly runs the
|
|
|
- * function instead of throwing, this might have side effects, possibly even
|
|
|
- * preventing the test suite from running correctly.
|
|
|
- *
|
|
|
- * prevent_multiple_testing(name):
|
|
|
- * This is a niche method for use in case you're testing many objects that
|
|
|
- * implement the same interfaces, and don't want to retest the same
|
|
|
- * interfaces every single time. For instance, HTML defines many interfaces
|
|
|
- * that all inherit from HTMLElement, so the HTML test suite has something
|
|
|
- * like
|
|
|
- * .add_objects({
|
|
|
- * HTMLHtmlElement: ['document.documentElement'],
|
|
|
- * HTMLHeadElement: ['document.head'],
|
|
|
- * HTMLBodyElement: ['document.body'],
|
|
|
- * ...
|
|
|
- * })
|
|
|
- * and so on for dozens of element types. This would mean that it would
|
|
|
- * retest that each and every one of those elements implements HTMLElement,
|
|
|
- * Element, and Node, which would be thousands of basically redundant tests.
|
|
|
- * The test suite therefore calls prevent_multiple_testing("HTMLElement").
|
|
|
- * This means that once one object has been tested to implement HTMLElement
|
|
|
- * and its ancestors, no other object will be. Thus in the example code
|
|
|
- * above, the harness would test that document.documentElement correctly
|
|
|
- * implements HTMLHtmlElement, HTMLElement, Element, and Node; but
|
|
|
- * document.head would only be tested for HTMLHeadElement, and so on for
|
|
|
- * further objects.
|
|
|
- *
|
|
|
- * test():
|
|
|
- * Run all tests. This should be called after you've called all other
|
|
|
- * methods to add IDLs and objects.

-/**
|
|
|
- * Notes for people who want to edit this file (not just use it as a library):
|
|
|
- *
|
|
|
- * Most of the interesting stuff happens in the derived classes of IdlObject,
|
|
|
- * especially IdlInterface. The entry point for all IdlObjects is .test(),
|
|
|
- * which is called by IdlArray.test(). An IdlObject is conceptually just
|
|
|
- * "thing we want to run tests on", and an IdlArray is an array of IdlObjects
|
|
|
- * with some additional data thrown in.
|
|
|
- *
|
|
|
- * The object model is based on what WebIDLParser.js produces, which is in turn
|
|
|
- * based on its pegjs grammar. If you want to figure out what properties an
|
|
|
- * object will have from WebIDLParser.js, the best way is to look at the
|
|
|
- * grammar:
|
|
|
- *
|
|
|
- * https://github.com/darobin/webidl.js/blob/master/lib/grammar.peg
|
|
|
- *
|
|
|
- * So for instance:
|
|
|
- *
|
|
|
- * // interface definition
|
|
|
- * interface
|
|
|
- * = extAttrs:extendedAttributeList? S? "interface" S name:identifier w herit:ifInheritance? w "{" w mem:ifMember* w "}" w ";" w
|
|
|
- * { return { type: "interface", name: name, inheritance: herit, members: mem, extAttrs: extAttrs }; }
|
|
|
- *
|
|
|
- * This means that an "interface" object will have a .type property equal to
|
|
|
- * the string "interface", a .name property equal to the identifier that the
|
|
|
- * parser found, an .inheritance property equal to either null or the result of
|
|
|
- * the "ifInheritance" production found elsewhere in the grammar, and so on.
|
|
|
- * After each grammatical production is a JavaScript function in curly braces
|
|
|
- * that gets called with suitable arguments and returns some JavaScript value.
|
|
|
- *
|
|
|
- * (Note that the version of WebIDLParser.js we use might sometimes be
|
|
|
- * out-of-date or forked.)
|
|
|
- *
|
|
|
- * The members and methods of the classes defined by this file are all at least
|
|
|
- * briefly documented, hopefully.
