[Wtr-general] Suite hanging sporadically

[Lisa Crispin]

Hi,
We have a suite of 33 tests with 1474 assertions that takes over 100 minutes
to run.  I run it every night with --runner=t and -b options.  Sometimes it
runs just fine, other times it just seems to hang up part way through, it
doesn't get an error, it is just sitting there.  This happened to me this
morning, and I stopped the testrunner and the traceback shows:
c:/ruby/lib/ruby/site_ruby/1.8/watir.rb:1383:in 'sleep': interrupt
           from c:/ruby/lib/ruby/site_ruby/1.8/watir.rb:1383:in 'wait'
           from c:/ruby/lib/ruby/site_ruby/1.8/watir.rb:2014:in 'click'
then it goes on to point to a line of code in one of our modules which is an
ie.button click, which never fails when we run just that script (and
normally never fails in the suite, either).

We ran the tests again and they ran with no problem.  I can' t figure out
why we're having these sporadic hangings or how to fix them.  The hangup
occurs in different places.  I run the suite with nothing else running on
the machine.  It's as if watir is dying somehow.  This has happened on a
couple of different machines, so I don't think it's the particular machine
or installation of watir.

We have a way to run a much shorter version of the suite; we pass in an
option that makes some scripts that would normally loop through 100 or more
scenarios just do one each, so that it only takes about 10 minutes.  This
usually works but every now and then it will also get stuck, usually where a
script is using autoit to click a modal dialog button.  The scripts never
fail when run directly, only sporadically from the suite.  We had a lot of
trouble getting that modal dialog problem licked, so that one doesn't
surprise me so much, but these hangups in other places do.

How can I run these problems to earth?  This is driving me nuts.  I
apologize if this isn't much information, but I'm not sure what to look for.
thanks
Lisa
