I want to POST data from Postman Google Chrome extension.
I want to make 10 requests with different data and it should be at the same time.
I guess there's no such feature in postman as to run concurrent tests.
If i were you i would consider Apache jMeter which is used exactly for such scenarios.
Regarding Postman, the only thing that could more or less meet your needs is - Postman Runner. There you can specify the details:
The runs won't be concurrent, only consecutive.
Hope that helps. But do consider jMeter (you'll love it).
In postman's collection runner you can't make simultaneous asynchronous requests, so instead use Apache JMeter instead. It allows you to add multiple threads and add synchronizing timer to it
