Using Jmeter with Okta SSO

Question

I'm trying to do performance testing on a web app which has Okta SSO enabled, so basically I get login screen wherein I add username and password, then it redirects me to a page where I have to write security pin, the caveat is that the pin is of 6 digits, and Okta randomly asks to write any 2 digits from my pin, unless I do that I can't login to the web app. Good news is, in my recorded scripts I see pinDigits which are actually the digits that Okta asked for so there has to be a way to capture that pinDigits value, please refer screenshot below -

Now I want to capture that pinDigits value and store my full 6 digit pin in an array, then once I have the value, I can pass the digit on the basis of index of the array to pin parameter from screenshot above.

Answers are highly appreciated

Thanks

Answer 1

1. For getting assistance on "capturing pingDigits value" you need to provide full (or at least partial) response from Okta and your Post-Processor configuration which does not work. It is not code-writing-for-free service and I have strong doubts regarding each community member having an application with Okta authentication installed somewhere. A swiss army knife solution for extracting "interesting" part of the response would be Regular Expression Extractor

2. With regards to storing pinDigits into an array just create 6 separate JMeter Variables like:

   pinDigit_1=9
   pinDigit_2=8
   pinDigit_3=7
   pinDigit_4=6
   pinDigit_5=5
   pinDigit_6=4
   

   So you will be able to refer 1st digit using ${__V(pinDigit_1)}, 2nd digit using ${__V(pinDigit_2)}, etc.

   If you will have another JMeter Variable holding Okta response, i.e. oktaDigit the syntax to get the combined variable would be like ${__V(pinDigit_${oktaDigit})}.
