What is "PrerenderBrowserTest.PrerenderHTML5VideoNetwork" and how can we make sure a patch doesn't break it?
(In reply to comment #5) > What is "PrerenderBrowserTest.PrerenderHTML5VideoNetwork" It's a chromium unit test (in the browser_tests suite). > and how can we make sure a patch doesn't break it? I don't know. Given the webkit bots/EWS/CQ can't run chromium's entire test collection (which can take hours), I'm surprised that a single chromium test failure is sufficient grounds to roll out a webkit change.

I made WebKit roll for solving a problem with chromeos bot and found that the test started to fail in chromium tree. Unfortunately I had not enough time for deep investigation. I'm sorry. fishcman and abarth were offline at the moment. I saw that the patch was related to chromium. Then I decided that the working test and the reverted patch are better than the disabled test and landed patch. It was single test but it was crashed on tha all platforms. Personally I'm not using webkit commit queue even for Web Inspector patches because it can break the build when I'm away. Chromium people can use try bots farm for testing chromium and webkit patches.
