[Webtest] ANT parallel Task

[Ruff Stefan]

Hi all,

we are using WebTest in a big Application (over 100 screens). One test takes about 3 minutes to run through the application. To run all our tests it takes more then 30 minutes. 
We want to reduce this time. Is it the right way to use ANT's parallel Task ?

We tried it out and it seems to work ! Is it luck that the WebTest report.xml was written correctly ?

Has someone experience with ANT parallel task and WebTest ?
thanks and regards
stefan, oli
