Bug 65579 – Several Tests of http://test262.ecmascript.org/ fail

• Component: JavaScriptCore
• Status: RESOLVED FIXED

Several Tests of http://test262.ecmascript.org/ fail

What is test262?

test262 is a test suite intended to check agreement between JavaScript implementations and the ECMA-262 Specification (currently 5th Edition). The test suite contains thousands of individual tests, each of which tests some specific requirements of the ECMAScript specification.

currently (WebKit nightly Version 5.1 (6534.50, r92131)) 866 out of 10927 tests fail

We're working on this. :-)

There numerous bugs tracking this, e.g.

https://bugs.webkit.org/show_bug.cgi?id=26382
https://bugs.webkit.org/show_bug.cgi?id=41876
https://bugs.webkit.org/show_bug.cgi?id=61014

Update:
* 51 new tests have been added which put us at 866 out of 10978 fail.
* Function.bind is now implemented, fixing 90 tests, putting us at 776 out of 10978 fail (775 when I fix a trivial issue that I set the number of args incorrectly!).

Looks like the biggest causes of failure are still the inability to delete static properties, and incorrect handling of numeric accessor properties on arrays.

This no longer depends on r61014.  That bug is not fully fixed, but has been fixed in all aspects that would be visible within ES5.

As of r97719 we're down to 568/11016 failing
(or more optimistically, up to 10448 passing!)

One note on the performance: Running those tests in WebKit nightly is way slower than running them in the current Mozilla Firefox 8.0. Firefox seems to be about a magnitude faster than WebKit on that testsuite (same machine of course)

To be more specific: the testsuite at http://test262.ecmascript.org/ runs quite fast in the beginning it just slows down significantly during runtime.

new results btw.: Tests To Run: 11108 | Total Tests Ran: 11108 | Pass: 10923 | Fail: 185 | Failed To Load: 0
