How to add assertions to the request inside while controller of Jmeter

Question

I'm using a jmeter script with while controller condition as

${__javaScript("${status}"=="Progress")}

Followed by one http request and from that request again I will extract the status. If the status is progress it will contine one http request inside loop else if the status success it will exit the loop. But i want to add assertion to ensure whether I get the status as success in the http request or not.

Because if i use assertion as Success in that http sampler, it checks all the reqest and obviously it will return false, and i need to add assertion only to the final http sampler of the while controller.

And so I can get error percentage with failing request in aggregate report and view results tree . Can anyone share your ideas please.

Answer 1

I would recommend using Response Assertion to verify if ${status} variable value is Progress OR Success

1. Add Response Assertion as a child of the HTTP Request sampler

2. Configure it as follows:

   • Apply to: -> JMeter Variable -> status
   • Pattern Matching Rules: Matches

   • Patterns to Test: Progress|Success

     

Given you use "Matches" rule JMeter will treat the pattern as a Perl5-style regular expression so if ${status} variable will be equal to Success or Progress the sampler will pass and otherwise it will be marked as failed.
