jmeter - How can i fetch data sequentially each row on each iteration fron csv file config on j meter

Question

I have set 4 virtual user on thread group and i have set csv file config having 2 rows of data.when i run the test the first iteration 2 virtual user is fetching data sequentially but in the next iteration the remaining 2 virtual user is fetching ramdom data not sequentially.I want to fetch data sequentially on the next iteration (1 user->first row,2 user->second row) next itetation(3user->first row,4user->second row) how can i achieve that?

Answer 1

I don't think you can achieve this using CSV Data Set Config as in case of concurrency you might run into the situation when pre-allocated entry for the user will be not sequential when it comes to test results.

If you want to have the following sequence:

• line 1
• line 2
• line 1
• line 2

no matter how many users/iterations you have and what is response times fluctuation you need to consider switching to __StringFromFile() or __CSVRead() functions instead of CSV Data Set Config
