Description Truitt Savell 2018-11-12 14:58:40 PST
The following layout test is flaky on MacOS Debug


Probable cause:

This test has become far more flakey than before and is timing out at around 80 seconds. Otherwise passes at around 30 seconds. We may need to mark test as slow for now until a solution is found. Needs to be reproduced.

I have been unable to reproduce this failure locally. I have been trying to reproduce using command:

run-webkit-tests --root debug-238908 imported/w3c/web-platform-tests/css/mediaqueries/test_media_queries.html --iterations 500 -f --debug

This tests seems to run a lot of sub tests and may be slowing down due to other factors during the test runner.

marked test as slow in https://trac.webkit.org/changeset/238932/webkit to see if more time will allow the test to pass on the bots.
Comment 4 Truitt Savell 2018-12-07 08:18:14 PST
it appears marking test as slow has brought this test back to green. no timeout has occurred in the lats 15 runs on any platform. Marking bug as resolved.
