Foreword
JMeter logic controller determines the order of execution sampler, and today we are together to learn about random control it!
Random controller: the controller is similar to Random alternate controller, that it is not different from a controller and through which the sub-sampler arranged in order, but in a randomly selected.
Example : adding random controller, setting the number of repetitions of the thread group 6 is added to a thread group "Get File List" request. Add two alternately controller requests: "download file A", "download file B"
After running, the controller can see the difference with alternating each time the randomly selected by the random time controller requests.
