CSS Transform Testplan

Overview

We are implementing 2d transforms for content in web pages. I don't think we are doing 3d transforms yet.

Test Strategy

Things we should do

• There are quite a few reftests being applied with the patch. Need to talk with Keith to see if these are enough and if there are more sanity "does it work" reftest patches needed.
• Test that multiple applied transforms equate to a sequentially applied transform
• Test invalid measurements
• Test invalid inputs
• Unneeded: we didn't implement these. Test DOM interfaces that this exposes - it doesn't seem the reftests do that.
• Test this with other embedded content and be sure the other content is (and is not) transformed as specified.
• Unneeded: it doesn't affect other elements - doesn't cause reflow Test with various types of :fixed, :relative elements on the page

Things we'd like to do

• Test applying these tranforms to SVG elements, as per the spec, see if it works
• Test how many of these transforms you can apply to one element
• Test handing these transformations off to DOM Threads
• Test with transparent images and backgrounds

Schedule Scoping

• Writing these tests will take about 3 days, because verifying that the transform is correct and coming up with the proper reference image will be a bit of a pain.

• The webkit browsers have a good share of these implemented (Google Chrome & safari)
