onunload

[Stefan Frenzel]

Hi,

I am load testing an ICEfaces application with WebTest.
The tests succeed until the application server’s JVM runs out of memory.
The used heap is increasing continuously.
Regarding to http://www.icefaces.org/JForum/posts/list/13140.page the JS
onunload handler must be called to avoid a memory leak.
Normally this is done by the browser when closing the page, etc. But
does WebTest/HtmlUnit also take care of it?
I started investigating the source code of HtmlUnit, however it seems to
me that no such handler exists.
There is the OnbeforeunloadHandler which is implemented only in a
HtmlPageTest test case. I am using WebTest R_1768.
I’ll try to include a invoke step in my test to call
http://<contextRoot>//block/dispose-views
<http://%3ccontextRoot%3e/block/dispose-views>. Do you have any other
suggestions?


Bye, Stefan

Off on a wild tangent unrelated to Webtest, but:

Am I correct in interpreting this to mean that the ICEfaces framework requires clients to send a POST to a certain URL when they unload the page, to help prevent excessive memory usage?

That sounds like a pretty wacky design - you shouldn't build something serverside that will fail unless the client's browsers play nice.

In other words, doesn't this mean someone could DOS an ICEfaces app simply by generating lots of http requests and never calling the /dispose-views URL?

Hi,

I'm trying to set up sqlunit tests with ant & webtest on stored  
procedure.
So I first build up a very simple mockup in order to tune tests  
execution & report creation
with a main folder containing all the stuff needed to perform tests  
(with less dependencies as possible)
But I get an error that I do not understand the root cause...

Error message:
<failure message="net.sourceforge.sqlunit.SQLUnitException: Unresolved  
compilation problem: The constructor XMLOutputter(Format) is  
undefined "/>

Can you please help me ??
Best regards
Olivier

To launch tests execution, in a console:
setup.bat
ant run

OS: windows XP SP2
Java: jdk 1.6.0_14
oracle 10g free edition (but I plan to use MySql too)
