JMeter : Using multiple CSV files

Question

The following is the scenario I want to run in JMeter: I have one CSV file (file1.csv) containing 100 userIds and passwords. I have created a Thread Group containing 100 users. I want each user to read one row of userId and password from file1.csv. For this I have added a CSV File Config element. Now, I want each of these users to read dynamic CSV file (for first row of userId and password from file1.csv it should read file2.csv, for second row of userId and password from file1.csv it should read file3.csv, for third row of userId and password from file1.csv it should read file4.csv and so on ) containing some rows. Each row contains parameters for a HTTP request.

Can anyone tell me how to do this in JMeter?

I am generating the one csv file(file1.csv) containing user name and password and other csv files(file2.csv,file3.csv,file4.csv and so on) containing some records.

Answer 1

The easiest solution would be adding a Counter test element or __counter() function to generate incrementing postfix for secondary CSV files on each iteration and using __CSVRead() function for extracting data from your file1.csv, file2.csv, etc.
