how to increment a global variable which has the unique access by virtual users?
I have a scenario, where 16 vusers will be using single csript. How to make the combined iterations that are run by all the users comes to 20.
You could use a parameter with 20 entries and set it to Unique Each Iteration and Abort User when out of values. That would be a brute force way to ensure only 20 executions with 16 users.
