How to fill CSV Data Set Config dynamically before running test?

Question

i have a page that creates bulk users in my application, and i was wondering if it's possible to use the created users and put them in my users.csv file (CSV Data Set Config element) so that i will use those users in the current test only.

the idea is to have dynamic users.csv file each test instead of fixed one, for all concurrent tests.

please advise, thanks.

Yes, You can do in the current test - But in a different thread group when you run consecutively.

Use BeanShell PostProcessor to write the created users in a CSV file as given below in the Thread Group 1.

import org.apache.jmeter.services.FileServer;

f = new FileOutputStream("CSV file Path.csv", true); 
p = new PrintStream(f); 
p.println(vars.get("username") + "," + vars.get("password"));
p.close();
f.close();

Then you can use CSV Data Set Config to read the same file and get the User Name , Password in the Next Thread Group.

If you want to use it in the same Thread Group, You can write in the CSV file - but use vars.get("username"), vars.get("password") in your test - as you can not read the CSV file yet to be created using CSV Data Set Config.
