Just so you don't think you're "Pat Malone", I have all these same
problems and have had them since I started using webtest years ago.
Yes, I have tried all the tips given so far (except the UTF one, that's
a new one to me) and I still get the memory usage accumulating until the
cpu finally is doing nothing but trying to manage memory and there
endeth the tests. "kaboom".
Yes I have a medium (not huge, not trivial) amount of tests doing very
ordinary things; no radical architecture or js libraries in use. If you
search back through the archives you'll find a regular history of
concerns about this memory bloat. Despite a number of on and off list
attempts to crack the problem on my set of tests, I still have the
problem and I split my tests into 3 large but consumable groups run via
a *shell script* to absolutely dump the jvm between tests. This works
but its grotty - I would get "marked down in an exam" - so I wouldn't be
shouting it from the rooftops as a success.

on 21/04/07 03:40 Tim Miller said the following:
I added the <enableJavaScript enable="false"/> to each webtest and ran
the tests. System memory remained at about 1.3 GB and tests completed
without running out of memory. Of course all tests failed as JavaScript
is required to have some of the forms appear on the page. With
JavaScript enabled system would be using about 2.9 GB of memory. First
failed step returns:
com.canoo.webtest.engine.StepFailedException: No suitable form found
having field named "field", Step: SetSelectField at
D:\home\qauser01\toolsv40\PortalTests\tests\common\steps\setAlertFilter.
xml:6: with (taskName="setSelectField")
I noticed that each returned page contains a JavaScript definition for
the menu items on the page which is fairly large. Our system uses a
third-party JavaScript package for menu handling.
