I am new to LR. I want to create a script to to stress the login of the application with different user id. Do I select init or action during recording. After I record the user ID and opasswors, during parameterisation what option do I select in prperties such that say i select 20 vusers, all of them login with different ids. Or should I select same user id and password for all 20 vusers. Can someone guide me on this. What would be the best way to go about.
