And if status code is other than 200 then wait for 5 sec and retry again. Jmeter - Regular Expression With variable contents. You will need 2 If Controllers (or eventually a Switch Controller to avoid copy and paste) The "Purchase" and "Home" samplers should be moved to be the children of the respective If Controllers; You will need to use a function like __jexl3() or __groovy() as If Controller expects the function or varible evaluating to trueFor example, if you specified Runtime Controller 10 seconds, JMeter will run your test for 10 seconds. If you want only one sampler executed randomly ( per iteration) you can use the random controller. jmeter. ) with child Throughput Controller set X percents (X is integer, 0 <= X <= 100) - so than X% from N loops is integer value too.
