Your second condition is flaky. 2. We have implemented the JMeter script, which you can find here, via the HTTP Request Sampler as shown in the 1st article, because this allows us to calculate the part of metrics that we cannot. Remember that variable names are case sensitive as well as "A" character so $ {Group} and $ {group} are totally different variables. if the failing sample is not the last sample under while controller, then remaining test element would be executed and then loop is exited. . The condition in the While Controller should be: $ {__groovy (! (vars. We can see that we have a few samplers under the Thread Group with 5 of these being children of the Throughput Controller.
