Willi / all, You're correct - my mistake. Each task inside the <parallel> element is a new thread. My example only had one task (and therefor one thread) per test. In my previous example, removing the </Parallel><Parellel> pairs should result in multiple threads executing at the same time.
And so I see the errors you were seeing Willi. There are two kinds: runtime and reporting time. The runtime errors appear to be overriding non-uniquely named data: Overriding previous definition of reference to ant.PropertyHelper Overriding previous definition of reference to step Overriding previous definition of reference to step Overriding previous definition of reference to step Overriding previous definition of reference to response Overriding previous definition of reference to response Overriding previous definition of reference to response Overriding previous definition of reference to document Overriding previous definition of reference to document Overriding previous definition of reference to document Overriding previous definition of reference to step Overriding previous definition of reference to response Overriding previous definition of reference to document Overriding previous definition of reference to step The reporting mechanism for webtest doesn't seem to be multi-threaded and there is race condition to write the summary report(s).

It would seem that, for now, Hesteric Roman and Stephen de Vries are current correct.

Mike's example Hi Mike, thanks for your tip. Your example is exactly the style a wanted to use. But : I think there works nothing parallel ! I think, only the parts in between one <Parallel> </parallel> statement works parallel. Now you have 4 jobs and all this 4 jobs works sequentiell. What do you think ? ********************* Willi / all, I was able to execute a parallel test with the following ant target example. I hope it helps. Description: starts four ant tasks with web tests. Each test repeats 10 times and keeps a counter. then prints the value and exits the task. I had not problems using this. <target name="experiment2"> <parallel> <webtest name="Parallel-1" description="experiment with parallel tests"> &configuration; <!-- <config> block, you probably don't need this line to try this test --> <steps> <repeat count="10"> <scriptStep description="js1" language="javascript"> var i = step.getWebtestProperty ('JSPropertyCount1') i++; step.setWebtestProperty('JSPropertyCount1', i); </scriptStep> </repeat> <echo message="Count(1): #{JSPropertyCount1}"/> </steps> </webtest> </parallel> <parallel> <webtest name="Parallel-2" description="experiment with parallel tests"> &configuration; <steps> <repeat count="10"> <scriptStep description="js1" language="javascript"> var i = step.getWebtestProperty ('JSPropertyCount2') i++; step.setWebtestProperty('JSPropertyCount2', i); </scriptStep> </repeat> <echo message="Count(2): #{JSPropertyCount2}"/> </steps> </webtest> </parallel> <parallel> <webtest name="Parallel-3" description="experiment with parallel tests"> &configuration; <steps> <repeat count="10"> <scriptStep description="js1" language="javascript"> var i = step.getWebtestProperty ('JSPropertyCount3') i++; step.setWebtestProperty('JSPropertyCount3', i); </scriptStep> </repeat> <echo message="Count(3): #{JSPropertyCount3}"/> </steps> </webtest> </parallel> <parallel> <webtest name="Parallel-4" description="experiment with parallel tests"> &configuration; <steps> <repeat count="10"> <scriptStep description="js1" language="javascript"> var i = step.getWebtestProperty ('JSPropertyCount4') i++; step.setWebtestProperty('JSPropertyCount4', i); </scriptStep> </repeat> <echo message="Count(4): {JSPropertyCount4}"/> </steps> </webtest> </parallel> </target> Mike ----- Original Message ---- From: Willi Kuhnis <[EMAIL PROTECTED] > To: [email protected] Sent: Thursday, December 20, 2007 11:55:18 AM Subject: [Webtest] Webtest parallel - where to use ? Hi, I want to make a stress test. I think, I could use parallel for this reason. But now I didnt find out a constellation, which works. When I use the <Parallel>-function inside the <Webtest>, then I get a error-message. Did somebody use it ? I tried it now on many different ways - without success. Also the following configuration dont work: <project name="ABC" default="test"> <target name="test"> <parallel> <webtest name="Test 1"> ... do someting </webtest> <webtest name="Test 2"> ... do someting </webtest> </parallel> </target> </project> Thanks for any tips. -- Willi Kuhnis [EMAIL PROTECTED] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ____________________________________________________________________________________ Looking for last minute shopping deals?
