jmeter - How to loop each thread with unique data from CSV Data Config file

Question

I have CSV data config file with 25 users. When I create a Thread group of 25 users I want each thread to pick one line from CSV Data config and loop around.

So

User1 picks userA
Users2 pick userB.......userN pick user(SomeX)

As I set keep alive so I want to reuse the connection and same set of data on the same socket.

My CSV file Recycle on EOF False
Stop Thread on EOF True
Sharing Mode : Current Thread.

But what I observed is Thread 1-1 User1 picks UserA ( iteration 1) Thread 1-1 User 1 picks User B iteration 2

What I expect is

Thread 1-1 User1 picks UserA ( iteration 1)
Thread 1-1 User 1 picks User A ( iteration 2 )

According to your description each JMeter thread will read CSV file independently and separately, i.e.:

• Thread 1-1 will process all 25 CSV entries defined number of iterations
• Thread 1-2 will process all 25 CSV entries defined number of iterations
• etc.

Given you have equal number of lines in CSV file and virtual users it might be better idea setting "Sharing mode" to All threads so each virtual user could pick its own line from the CSV file.
