Jmeter multi-user execution

Question

I have a JMeter execution scenario. Here it goes:

1. Login with 1 credential.
2. Perform an operation.
3. Logout.

Now, issues: I need to login using 1 credential and play the operation part with multiple concurrent users, even though I have just 1 login credential. How do I execute such a scenario ?

Please explain the whole procedure in detail as following an instructional overview sometimes leads to blockage in moving further.

Thanks!

Answer 1

Go through the following guide to setup the rest of the test

You need to use once only controller for login action. Ideally you want to use different users to avoid race conditions caused by using the same user.

Answer 2

If your system allows multiple logins with the same credentials it should not be a problem, just add as many users as you need in the Thread Group and each of the virtual users will execute these 3 requests upside down.

You can add __threadNum() function as the request label prefix or postfix in order to be able to distinguish virtual users and ${__jm__Thread Group__idx} pre-defined variable to track Thread Group loops/iterations.
