Description Rafael Weinstein 2012-05-29 13:20:45 PDT
The original test was broken into five parts by the previous chromium gardener, but each part is now timing out.

Are these tests really this slow, or is this a bug?
Comment 1 Nikolas Zimmermann 2012-05-29 13:25:31 PDT
These tests was splitted in r87726. Are there still problems after the split? Marcus should know about this.
Comment 2 Rafael Weinstein 2012-05-29 13:30:46 PDT
Yes. All five splits are still timing out.
Comment 3 Rafael Weinstein 2012-05-29 13:53:22 PDT
marked as TIMEOUT in r118829

Chromium has a shorter timeout than other WebKit ports (6 seconds on release and 12 on debug). We could mark these tests SLOW in the test_expectations.txt file and that would give them 30/60 seconds respectively. Testing locally, they complete at that point, but fail with a text diff.

Looking at http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=svg%2Fdom%2Fviewspec-parser- these tests are slow on all ports. Taking up to 19 seconds on GTK debug and 30 seconds on Lion Release with a high variance.

Is there any way we can make these tests faster? More importantly, why are we running fuzzer tests as part of the layout test suite? I realize that the randomization is deterministic, but this still doesn't seem appropriate in principle for layout testing. We run a fuzzer to find problems and then create dedicated reduced test-cases for those.

These tests also timeout a lot on Mac:

FYI, webkit-dev discussion about this: http://lists.webkit.org/pipermail/webkit-dev/2012-June/021110.html.
