how to delay a HTTP request when assertion failed - in recorded jmeter script

Question

I have a recorded script for my web application load testing. In one of the HTTP requests, i need to check Response message for "Completed" status text. If Status is not "Completed" then i need to run a loop 5 times to check if status is "Completed".

I know about assertion where i can check for "Completed" status but not sure how to make HTTP request wait and check in loop for 5 times before it moves to next HTTP request.

Any help would be appreciated. Thanks!

Please find the attached sample test plan implementing the above logic.

Answer 2

You can use Loop Controller + If Controller to achieve your requirement.

The test plan should be almost as given below.

Lets assume we have a variable completed.status = false

If condition should be "${completed.status}"=="false" to make a first call by default to get the status.

The Beanshell assertion should change the completed.status = true whenever the condition is met.

If the condition is not met - Beanshell should create another variable for the timer vars.put("wait", "3000"). Use ${wait} for the timer to wait for 3 seconds to make another call. So that timer does not delay if the status is 'completed' in the first call itself!!
