Hi!
To do load/stress-testing with soapUI Pro you need to go through the following steps:
1) Create a TestCase containing the requests, etc. you want to test under load
2) Right-click the created TestCase node and select "New LoadTest"
3) In the created LoadTest, set your desired strategy and settings, and run the LoadTest with the run button..
Hope this gets you started.. please post again otherwise or if you need more info!
regards,
/Ole
