Testing with JMeter?

Question

Software testing

DD, I have a question for testing with JMeter.
I have 15 API post requests, and I need 1 user to send in 1 second to all these 15 api. The request is sent to all apishki, but not simultaneously, but sequentially. 1 request went and the answer came then the next request. And how to do it at the same time and what timers, samplers you need.
2nd question now when I increase the number of users, for example 10 users and another problem, the request is sent like this first 10 users to the first apish, then 10 users to the second apish and I need to first 1 user for 15 apish, then the user again 15 apish request at the same time my input data is changing and I need 1 user to send the same data for 15 apishok and the next user send other data for 15 apishok, thanks

Answer 1

1. To send parallel requests, there is bzm - `Parallel Controller`.
2. Most likely your list of users is not located correctly, try to take it out of the coil and check the result.
