This basically means that you can run samplers only if a certain condition is true. 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. net. How to do this is JMeter. The better way is to use a Loop Controller and a Counter. If the time difference is 15 minutes (900000 ms) then IF controller should execute for the token id generation. 5 observe the output. In a JMeter test plan, I have 4 thread groups which will be executed consecutively, however there is a dependency of certain variables from one thread group to another and hence, in case of any sampler failure in previous thread group, the execution of subsequent thread groups should stop.
