[webkit-dev] new style for JavaScript layout tests

[Maciej Stachowiak]

Hi everyone,

I've redone most of our JavaScript layout tests (in LayoutTests/fast/ 
js to use a new style based on how the KDE JS tests work.

I'd like to ask that all new JavaScript layout tests be done with  
this new style.

To make a new-style JS tests, you make a new .js file in LayoutTests/ 
fast/js/resources using shouldBe() assertions. Then run the new make- 
js-test-wrappers script in WebKitTools/Scripts, and a new .html file  
that loads your script will be generated in LayoutTests/fast/js

Here's an example of a test JavaScript file, has-own-propery.js:

description(
"This test verifies the behaviour of Object.prototype.hasOwnProperty,  
as documented in ECMA-262 rev3 section 15.2.4.5."
);

shouldBe("typeof {foo : 'yum'}.hasOwnProperty", '"function"');

shouldBeTrue("({foo : 'yum'}).hasOwnProperty('foo')");
shouldBeTrue("''.hasOwnProperty('length')");
shouldBeFalse("({foo : 'yum'}).hasOwnProperty('bar')");
shouldBeFalse("({foo : 'yum'}).hasOwnProperty('toString')");
shouldBeFalse("''.hasOwnProperty('toString')");

var successfullyParsed = true;


When you load has-own-property.html in a web browser, the results  
look like this:

This test verifies the behaviour of Object.prototype.hasOwnProperty,  
as documented in ECMA-262 rev3 section 15.2.4.5.

On success, you will see a series of "PASS" messages, followed by  
"TEST COMPLETE".

PASS typeof {foo : 'yum'}.hasOwnProperty is "function"
PASS ({foo : 'yum'}).hasOwnProperty('foo') is true
PASS ''.hasOwnProperty('length') is true
PASS ({foo : 'yum'}).hasOwnProperty('bar') is false
PASS ({foo : 'yum'}).hasOwnProperty('toString') is false
PASS ''.hasOwnProperty('toString') is false
PASS successfullyParsed is true

TEST COMPLETE

In addition to shouldBe, shouldBeTrue and shouldBeFalse, there are  
also shouldBeUndefined, shouldBeNaN and shouldThrow assertions.

Regards,
Maciej
