I have total API 13.
Need to achieve TPH 100PER HOUR for each transaction.
a user can't use 2 times it means for each iteration need unique user. And
1 iteration takes 80 sec.
So, how many users/thread need to give and what should be loop count.
How to pass unique user each tims?

I am running while loop till I get a desired response. But what happening is, if my desired response is in the 10th iteration. Before 10th iteration if I get an error then that is being counted as a failure.

Either you have to fix the error, skip the error using a condition or you can ignore it ..

Hai sir I need help . In my case I have an API which is a batch process. After that API i will get a key. Since it is batch process, in load testing batch is in process so that I get an empty key in next API. I need to wait till batch complete how can I implement in load testing

[@littleslawyoutubechannel]

Got it, so in that case add a thinktime so the test will wait until the api key is generated and then you will get the api key for the next request . Hope this helps. Please let me know if you need any information

@@littleslawyoutubechannel I have tried using a constant timer but it is not working sir, I used while controller but the loop is running infinitely and the following API's not running

[@littleslawyoutubechannel]

@@SwapnaBalakrishnan-cb1es add a uniform random timer inside the request which will give you enough thinktime and delay

[@piyushgarde1647]
