Iterate over csv file with While Controller

Question

I try to iterate on a .csv file with a While Controller. I want only one iteration.

The condition used for stop the loop is the follwing one : ${__javaScript(vars.get("TestCaseName") != "")}

Thread Group config

• Number of Threads : 1
• Ramp-Up Period :
• Loop count : 1

CSV Data Set Config

• Variable Names : TestCaseName
• Recycle on EOF : False
• Stop thread on EOF : True
• Sharing mode : Current thread

However, an infine loop is generated...

Can you help me please?

Thank you !

Answer 1

1. Put your CSV Data Set Config inside the While Controller

2. Amend the While Controller's condition to use:

   • __groovy() function as since JMeter 3.1 you should be using Groovy for scripting

   • __jm__While Controller__idx variable to stop after the first While Controller's loop

     ${__groovy(!vars.get("TestCaseName").equals("") && (vars.get("__jm__While Controller__idx") as int) < 1 ,)}
