ACID3 Tests

September 3, 2008 · 11 Comments

With all the fuss about Google Chrome scoring 75/100 and a fresh round of comparisons of compliance (Safari on Mac gets 72, FF3 on Win gets 69 I believe?), it's interesting to read that an internal Alpha of AIR scores 100 according to Ted Patrick. Very impressive! {posted via Google Chrome - on a Windows XP VM on my MacBook Pro}

    Webkit, which AIR uses, has passed since March. This is more about Apple producing a high quality rendering engine than anything to do with AIR itself, imo. http://webkit.org/blog/173/webkit-achieves-acid3-100100-in-public-build/

    @Phil, yes, if you read Ted's post he makes it clear that WebKit is the star here - the "big news" is that AIR will rev to the latest WebKit soon so it too will pass ACID3.

    what's this webkit scoring 100 all about? Isn't webkit Safari's web engine? When I run the test in Safari I score a 72 as well...

    I must be confused?

    btw I'm on a Mactel...

    @Sal, WebKit is updated separately from Safari. The current release of Safari (like the current release of AIR) is based on an earlier WebKit that did not get 100%.

    IE8 Beta 2 scores a massive 20/100! Go Microsoft!

    I'm a bit sad that FF3 only scores 71/100 on my MacBook.

    Has anyone tried Opera?

    The Safari 4 Developer Preview which has been out for some time gets 100. I'm not sure if that's going to get pushed out with 10.5.5 though.

    It also has a cool feature to save a page to open as a stand alone "application". This allows you to run any page as a totally separate process without the browser UI chrome.

    The Mozilla Gecko developers have said repeatedly that they think the Acid tests are essentially worthless and that they'd rather spend their time working on other things. Without getting into that I just thought I'd share why that browser hasn't and probably won't get 100 for a long while.

    It is pretty amazing that Safari, which has barely been around 5 years, has taken the market by storm showing up in AIR, Android, phones and probably other internal projects.

    @Elliott,

    Safari is not in AIR or Android. Webkit is the browser used. Safari is based on webkit. Webkit has been around longer than Safari.

    @Bash

    Woops, that's a brain fart on my part. s/Safari,/Webkit,/

    I'm well aware of the difference as I've done a number of bug reports and regression testing for the project. ;)

    Strictly speaking Webkit isn't a browser either. It's a rendering engine that could be used to build browsers or any number of things. For instance Adium uses it for message display and easy theming.

    @Bash, @Elliott, and of course the confusion is compounded by the fact that you can d/l and install a nightly build of WebKit and it looks just like Safari, even down to the basic icon. I'm running WebKit nightly builds as my default browser on OS X (and Chrome on WinXP).

    Because different builds of WebKit are being used, the Acid3 results may differ.

    WebKit passed Acid3 fully for the first time last week. So it's 100 subtests of 100 passed now.

    <a href="http://tekkie.flashbit.net/browsers/first-browser-to-pass-acid3-web-standards-test#opera-960-beta-acid3-result">Opera 9.60 Beta scored 85</a>.
