Waiting for all thread ('user') before continuing the test
Hi,
I have the following test to do :
I have 15 users that does some work (they have to register DVD, etc) on the
website I have to test. When this work is done, another people must do a
specific action : I'd like to wait for that specific action, before
continuing the test, where I need those particular action to be made.
Here is a "graphical" view of my test and what it should looks like :
WhileController: Is there some dvd to register ?
HTTPSampler: register it
If not last user :
Wait
Else
Do the unique action (eg: only one thread should do it)
Prepare data, and wake up all other user/thread
End
I can't separate this into severall test, as it is how it works.
In term of Java, that would means something like this :
synchronized (nbUserThatFinishedTheTest) {
++nbUserThatFinishedTheTest;
if ( nbUserThatFinishedTheTest == nbUserThatMayFinishTheTest ) {
doMyAction();
nbUserThatMayFinishTheTest.notifyAll();
} else while (nbUserThatFinishedTheTest<nbUserThatMayFinishTheTest)
nbUserThatMayFinishTheTest.wait();
}
Before trying to make some "waiter" component, i'd like to know if it is
advised to do such in jMeter? (I'm not the architecturer of jMeter, so) (and
if it already exists, in that case that would be stupid to it).

Please create a Bugzilla issue. You can then attach the JMX file,
jmeter.properties and jmeter.log.

java.util.ConcurrentModificationException while running tests
Posted by Gaël LHEZ <gl...@glowria.fr>.
Hi,
I've got the following error while running my test :
2006/05/17 10:16:47 ERROR - jmeter.gui.action.ActionRouter:

The test looks like this (note: if newer version of jMeter could use the
java.awt.dnd and java.awt.datatransfer package to manage drag and drop, and
to set up a text version of tree node, so that we may copy it from jmeter to
any app...)
Root
|- Test 1
| |- Include test1.jmx
|- Test 2
| |- Include test2.jmx
|- View result in table
The test does not run at all, except if I flood the event dispatch thread
with Ctrl + R (well : if I try to run the test multiple times)
I can provide the test used if needed.

Well, I could separate this into three part, but in the same thread
group (eg: I want the same user at beginning and at end). In a
browser context, that would be one user per PC.

You mean synchronized timer ? I've got to try it.
Is there some compagnon to that timer (I'd like to avoid using If
Controller as it seems bugged), which would allow me to do an action
once for the thread group (eg: only one thread do it). That action is
a long one, but with two synch' timer that should do it.

Why not?
Are they not different users?
If you were testing with a browser, would you have to do it all in the
same session?

There is a synchronisation controller.
You can create two thread groups, and run them consecutively.
