Purpose of Throughput Controller?

I need some help to use JMeter. I want to record two different scenarios like clicking 2 different buttons. If i try to run for 2 users, one user should hit first button, another should hit another button concurrently.

I know this is the basic question. But i am new to this one. Thats why asking here. I have tried like below:


Thread Group
 -Throughput Controller
       --Login
       --Clicking 1st button
 -Throughput controller
       --Login
       --Clicking 2nd button

When i run with 2 users using CSV Data Set Config, both login takes same user.

And also i need to test for concurrency. I am not sure how to execute this one correctly. Could anyone can help me in this?

  1. Throughput Controller will work correct if you have more than single iteration.
    I.e. you should have N loops (using Loop Controller e.g.) with child Throughput Controller set X percents (X is integer, 0 <= X <= 100) - so than X% from N loops is integer value too.
    You may look into this discussion for better examples and explanations.

  2. For your case you can try to use construction like the following:


Thread Group
Number of Threads = 2
Loop Count = 1
+- While Controller
   Condition = ${__javaScript("${login}"!="<EOF>",)}
   +- CSV Data Set Config
      Filename = users.csv
      Variable Names = login,pwd
      Delimiter = ,
   +- Loop Controller
      Loop Count = 10
      +- Login
      +- Throughput Controller
         Percent Execution
         Throughput = 50.0
         +- Clicking 1st button
      +- Throughput Controller
         Percent Execution
         Throughput = 50.0
         +- Clicking 2nd button
      +- Logout

where
- there are 2 threads (Thread Group: Number of Threads = 2) started simultaneously each with unique credentials extracted from csv-file (While Controller + CSV Data Set Config), used for Login;
- the whole test-flow - login > click button (either first or second) > logout - will be repeated N times using Loop Controller, which one makes Throughput Controller work.
