how to use separate csv file for each thread

Question

My scenario is like, 1. Login by multiple users (100 users) 2. Select 50 items by id's specific to user

I have placed id's for each user in separate csv file say user1.csv, user2.csv, user3.csv and so on.

My result should be like Thread 1 should take user1.csv and process all 50 id's in loop controller. Thread 2 should take user2.csv and so on.

I tried with below example, but still couldn't find the solution.

Eg. I used file path as C:\abc\user${_threadNum}.csv

Or

C:\abc\user${_threadNum}.csv

Variable name in csv file is user_id

Requeat will look like /home/abc/${user_id}

I want thread 1 to use the user1.csv file and substitiue the value of user_id in the request and thread 2 should use user2.csv and so on.

If I execute my above plan, I am getting error as /home/abc/EOF

How is this possible in JMeter? Or any other approach?

Please provide solution with an example, since I am new to JMeter.

Answer 1

Create your files like comman_name_1,comman_name_2,comman_name_3 etc. & select current thread option from dropdown list present in csv data config set.This will allow threads to use different files per thread or put values in a single file and select current thread option.

Answer 2

It's easy, just add CSV Data Set Config to each thread (user1.csv for thread1 and so forth). Configure CSV Data Set config, and select one of this values in Sharing mode field:

• Current thread group - each file is opened once for each thread group in which the element appears
• Current thread - each file is opened separately for each thread

UPD: I have done it right now, it works

Script looks like this:

I selected 'Current thread' in each CSV Data Set Config

I was making the mistake of using single underscore in fetching the count of thread. We need to use double - underscore like this : ${__threadNum} Note :
