If we now replace our static Loop Count value in the Thread Group to use our ITERATION_COUNT Property. props.put("ITERATION_COUNT", testSequence.size().toString()); And finally assign the size of the testSequence array to a JMeter Property called ITERATION_COUNT. bzm - Concurrency Thread Group "Thread Iterations Limit:" forever? Controllers in JMeter: Loop, Simple, Transaction, Module, Random - Guru99 For example, if the loop count is 2 and number of threads is 100 then the script will run 200 times. The different types of Samplers like HTTP requests are added as child of these Thread Group elements to simulate the requests made by users to the server. In Thread Group GUI, you can control the number of simulated users (threads), the ramp-up time (how long it takes to start all the threads), the loop count (or iteration count, and optionally, a start and stop time for the test. JMeter provides different types of functions to the user, in which that loop count is one of the functions that is provided by the JMeter. http503.com.
