This is outstanding!! I am working on designing a Performance Test framework for my Applications APIs. I am done with creating my production ready design within 10 days.... All because of you. I did not refer any other sites or videos.... Your explanation is so simple and powerful... Kudos to you... Thank you Brother..
If my manager appreciates on looking at design... the tribute will go to you.. :-)

Hi Raghav, I have Extracted the Auth Token using Json Extractor into a variable, and I want to use that particular variable into my each API (around 40 APIs)Headers of my test plan. Is there any way to use that Variable one time and my Auth token will work for all the APIs?
Thanks in Advance

[SandyShiralkar]

I have Jmeter tests where I use Bearer token, these tokens expire after some time, so when i try to run a longevity test, the test fails after the tokens expire, how do i regenerate the token just about the expiration time so that the tests do not fail.

Hi Raghav,
Could you please elaborate why we have to give default value for json extractor when you have used more than one variable and json path expression?

Thanks Ragnav, great tutorials!
I have a question about JSON extraction. What if i need to cycle though values in ${USER1} like ${USER1_1}, ${USER1_2}, etc?
I have multiple images, which are to be loaded, if response is not empty, so i call If statement, then extract url of images using JSON Extractor,
but after i dont know how to cycle request using those images url's. Maybe you have some advise?

$..count; $..Id - not working
Names of created variables - count; Id
