JMeter - Pause threads for a random number of seconds when a specific code is returned from an API call

Question

I have a situation where I need to pause all of the threads to a particular endpoint when I receive a specific error code from the response. So I basically need to look for this error code (ex. 404) and pause for a random num of secs b/t 3 and 10. Below is my current test structure. I have looked at the logic controllers but I am unsure how to implement. I assume that I would need to wrap each request with this logic. Thanks for your help!

• Test Plan
  • Thread Group
    • CSV Data Set Config
    • HTTP Request 1
    • HTTP Request 2
    • Summary Report

Answer 1

1. Add Regular Expression Extractor as a child of the HTTP Request sampler which code you need to extract and configure it as follows:

   

   it will save response code of the sampler into ${code} JMeter Variable

2. Add If Controller after this sampler and use the following __jexl3() expression:

   ${__jexl3(${code}==404,)}
   

   it means that If Controller's children will only be executed if the Sampler will fail with 404 status code

   

3. Add Flow Control Action sampler as a child of the If Controller and configure it as follows:

   

   this ${__Random(3000,8000,)} function will generate random think time between 3000 and 8000 milliseconds which seems to be exactly what you're looking for
