Read csv value in loop controller Jmeter

Question

I have a loop controller in thread groups to read one csv file and i want to read all line in this csv file. I config my thread group as below:

• Loop Controller (4 times)
• • Read csv file (Recycle on EOF: False, Stop thread on EOF: True, Sharing mode: All threads)

I run this scenario with a number of threads: 2

• With first thread, read the first line of CSV file

• With second thread, read the second line of CSV file

After each loop, i got data from CSV file is not changed, so how can i read each line of csv (from 3rd line,...) after the loop?

You have to put CSV Data Set Config as a child of Loop Controller.
It should work for you with CSV Data Set Config settings you specified. I create Test Plan:

    Thread Group
    Number of Threads = 2
        Loop Controller
        Loop Count = 4
            CSV Data Set Config
            Filename: ... (your csv-file here)
            Variable Names: number
            Delimiter: ,
            Recycle on EOF = False
            Stop Thread on EOF = True
            Sharing Mode = All threads
            JSR223 Sampler
            log.info(vars.get("number"));     // output ${number} variable values

Each Loop my "CSV Data Set Config" reads line into a "number" variable.
JSR223 Sampler print it's value to Log Viewer.

My CSV file looks like

1
2
3
4
5

So, because of Recycle on EOF is FALSE, Stop thread on EOF is TRUE the first Thread read 4 lines in the loop and the second Thread read just one the 5th line and then stop.
