How to terminate the test when reaching the request sample to some 1000 request in Load UI Pro?

Thank you for posting to our Community Forum. 

 

You can use a "Test Case Run" assertion on the Load Scenario with the option "Stop Test on Failure" checked so that the Load Test terminates if the TestCase runs past 1000 times.

Have a great day!
