Description Jessie Berlin 2012-08-31 16:07:05 PDT
This is apparently expected behavior (since empty results were checked in for mac when the test was originally added in http://trac.webkit.org/changeset/109953), but I don't understand why. On Mountain Lion, there is actually a layer tree printed:

http://build.webkit.org/results/Apple%20MountainLion%20Debug%20WK2%20(Tests)/r127318%20(503)/css3/filters/composited-during-animation-layertree-pretty-diff.html

Why are we expecting empty results on Lion? Is some feature not on in Lion?

I am going to add the expected results for ML and move the empty results to mac-lion to get the bots greener.

This test sometimes (rarely) produces empty results on all Mountain Lion bots (WK1 and WK2).

Also, I can reproduce getting empty results every time when it's run repeatedly:

$ run-webkit-tests css3/filters/composited-during-animation-layertree.html --repeat-each 100
…
[2/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
[3/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
[4/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
[5/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
[6/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
…
