As Advanced actions are virtual user actions, they can be combined with the other available logical actions (Loop, While, If...Then..Else, Try...Catch, etc.) in order to reproduce realistic and adapted behavior.
Learn more about Logical actions.
Use Rendezvous points to synchronize the various Virtual User instances so that they can run the End User Experience scripts at the same time.
For more information on Rendezvous points, please refer to Use Rendezvous points.
Use Pacing (minimum runtime of a Container) and Delay to ensure that End User Experience scripts are run in regular intervals.
The use of a variable in the Custom action parameters allows you to change the name of the User Experience script to be run, or the mobile to be used, throughout the test.
