Some of the most interesting work is only hinted at in the blog. IE 10 PP2 now leads on EcmaScript standards conformance.

IE 10 only fails 7 tests compared to 200 for Firefox 5 out of a total of 10000 tests.

I don't use Opera, but according to this page http://en.wikipedia.org/wiki/ECMAScript Opera lags the other browser and fails 3000 tests. Does anyone have Opera and willing to run the conformance test here: http://test262.ecmascript.org/

Opera version 11.50 (most recent) on Win7:

Tests To Run: 10935 | Total Tests Ran: 10935 | Pass: 7061 | Fail: 3874 | Failed To Load: 66

The fast majority (80%) of the error log appears to be in section 15.2.3, with half of the rest also being in section 15. This would imply that around 1/3 of the entire test suite is just in that section of the specification; as the test itself describes, its coverage is currently incomplete.

I was pretty certain that Opera's reported score couldn't be that bad. I am definitely very suprised.

Overall, I have to say, I am a huge fan of having these thorough tests come to web standards. So that browsers can't just say "We support HTML5". I am really tired of the buzzword nature of standards recently. Hopefully, this will get all browsers to step up their game.

FF5 is a production release, IE10 is a "platform preview". Not exactly a fair comparison.

That's a good point. It would be interesting to get a read on the latest Aurora builds. I might install it and do it later today.

I can help with that, I am running Nightly 7.0a1 (2011-06-29) My results: Tests To Run: 10935 | Total Tests Ran: 10935 | Pass: 10732 | Fail: 203 | Failed To Load: 0

Then FF5 should fail less of the tests, right? Since a production release should be more stable than a platform preview?
