First Look At the ACID3 Browser Test

Posted by kdawson on from the turn-on-tune-in-render dept.

ddanier writes "Now that all major browsers have mastered the ACID2 test (at least in some preview versions), work on ACID3 has begun. The new test will focus on ECMAScript, DOM Level 3, Media Queries, and data: URLs. 100 tests will be put into functions each returning either true or false depending on the result of the test. The current preview of ACID3 is still missing 16 tests."

    It is hard for me to understand the logic that once a new test is created that everything is incompatible again.. Doesn't everything still pass the acid2? I thought that the acid tests were testing stuff that was already supposed to be an included feature to see if it worked. the acid test itself isnt REALLY what determines standards compliance.... is it?!

    Safari 3.0.4 (Windows) hangs at 60, Internet Explorer 7.0.5730.11 messes up so badly the result can't be read...

    The test looks interesting, for sure. And it's going to raise the game for standards compliance!

  3. Where is the reference image from? by Aaron+Isotton · · Score: 4, Interesting

    Something I always wanted to know (applies to the older Acid tests, too): how do they render the reference image? Is someone creating them by hand? How do we know no mistake was made when creating the reference image?

      You don't

      I remember an article by the Apple guy who made ACID2 work on Safari (I think this was the first browser to make it work). One of the steps to get it working was to fix a bug in the test, when he couldn't make the reference result fit with what the test HTML said.

    We write those tests too, they're called test suites and if you look at my site you'll find literally hundreds if not thousands of them:

    The Acid tests are easier for the less technically inclined to get a hold of. In practice, the browser vendors take Acid tests and turn them into small tests of the kind you describe before fixing them. For Acid2, I was the one who did a number of those small tests for Opera (I worked for Opera at the time) -- you can see them here:

  5. Since when is vaporware acceptable as proof? by jbn-o · · Score: 2, Interesting

    Now that all major browsers have mastered the ACID2 test (at least in some preview versions) [...]

    When Firefox makes news on this there are daily builds to test, source code to inspect and compile. One can see the progress first-hand.

    There is no build of Microsoft Internet Explorer 8 to test. You are accepting something unverifiable as reality and thus talking about these browsers as if they're all on the same level. This suggests a new low: believing the illegal monopolist who tells you that their vaporware behaves in accordance with published publicly-implementable standards.
