Jmeter problem

[Chaz Camron]

Hi,

I'm new to Jmeter. I recorded a basic test script ( user logs in to the system and logout) When i run it for more than one user thread. I'm getting a message ' user already logged in' . If i run the script for one thread this doesn't happen. My question is, when we are doing a load test for many users ex (200) do you have to have a csv data file that include 200 user names and 200 passwords to do a load test for 200 users?

The application im recording only allow one user to login at a time. If a user is logged in you cant login with same user credentials from another machine.

Yes you have to create a csv data set (Add > Config Element > CSV Data Set Config)
