386910 - scriptaculous test fails when running slowly

Status: NEW

(Core :: DOM: Core & HTML, defect, P5)

Description

The scriptaculous test, dom/tests/mochitest/ajax/scriptaculous/test_Scriptaculous.html , seems to fail when running slowly.  It failed once on the tinderbox earlier today, and I reproduced the failure running it under valgrind (thinking that that might show a reason for random failure).  Valgrind didn't show any warnings, but the test failed in exactly the same way, which suggests to me that there's something timing-dependent in the test that fails when the test is run slowly.  The failures that showed on both the tinderbox and for me are:

not ok - testInPlaceEditor 31 assertions, 2 failures, 0 errors Failure:
assertEqual: expected "'Server received: To be edited'", actual "'Saving...'"
Failure: assert: got "false"
not ok - testInPlaceEditor 31 assertions, 2 failures, 0 errors Failure:
assertEqual: expected "'Server received: To be edited'", actual "'Saving...'"
Failure: assert: got "false"
not ok - testHovering 1 assertions, 1 failures, 0 errors Failure: should be
transparent after mouse leaves element: expected "'transparent'", actual
"'rgb(255, 255, 175)'"
ok - testLoadsTextFromServer
not ok - testLoadsTextFromServer 3 assertions, 2 failures, 0 errors Failure:
assertEqual: expected "'Text from server'", actual "'Loading...'" Failure:
assert: got "false"
not ok - testLoadsTextFromServer 3 assertions, 2 failures, 0 errors Failure:
assertEqual: expected "'Text from server'", actual "'Loading...'" Failure:
assert: got "false"

I also saw an additional failure at the very end that the tinderbox didn't:

ok - testElementCollectTextNodes
ok - testElementCollectTextNodes
ok - testElementCollectTextNodes
not ok - testElementCollectTextNodes

(I just ran the tests using valgrind --tool=memcheck --leak-check=no --trace-children=yes --num-callers=500 perl ./runtests.pl and then clicked on the test I wanted to run.)

These tests are still failing intermittently on Tinderbox, see:

I see similar failures when running on fennec on the Nokia device (I don't see any issues with fenneco n the desktop though):

Oddly enough, I think these pass on the maemo device when run outside of the mochitest framework.  We might need to look there as a starting point.
