Recent compatibility updates

In the past two months or so I’ve done a lot of compatibility testing, and I thought I’d give you an update.

I’m increasingly posting my real-time raw test results and announcing new versions of tables on Twitter; so if you’re interested in that data you can follow me.

The last round of testing (last week) added IE8 final, Safari 4, and Chrome 2 to the roster of browsers, while earlier on I already admitted Opera 10a and Chrome 1. With this confused policy in mind the updated compatibility tables are:

• CSS; in all new browsers.
• W3C CSS Object Model; in all new browsers.
• DOM Events; in Opera 10a and Chrome 1.
• DOM CSS module; in Opera 10a and Chrome 1.
• DOM HTML module ; in Opera 10a and Chrome 1.

The Master Compatibility Table contains an overview of where the testing stands right now.

You may notice that I’ve removed Safari iPhone from the regular tables; that’s because, in addition to the normal testing work, I’m also working on the mobile compatibility tables, and of course the iPhone belongs in that group.

After some initial confusion about exactly what I should test and what Vodafone has available, I have now created a test roster of 19 browsers on 13 phones; enough for the moment. I’m especially trying to figure out how much difference there is between various Opera Mobile installs and various S60 WebKit installs. The answers seems to be “quite a bit” and “hardly any,” respectively.

I’ll continue to test four separate installs of S60 WebKit, but I’m already pretty certain that I’m going to merge them into one entry in the not-too-distant future.

Currently the mobile tables are:

• CSS support; with 17 out of 19 browsers tested. I left out some of the less vital CSS declarations, though I tested all selectors.
• Miscellaneous tests; with generally 13 out of 19 browsers tested. Basically I used these tests to get a feeling for what’s important to test on mobile phones. Turned out font-style: italic had to be tested, so I’m glad I took it slow.
• W3C CSS Object Model; currently only four mobile browsers tested.

Again, if you want to see my conclusions as I draw them, follow me on Twitter.
