JMeter - How to run parallel execution with CSV as dataset?
What I am trying to accomplish => Run 50 threads in parallel using a CSV file as the dataset.
Here's how the CSV looks like (Let's say there are 50 records):
Username,Password
user1,password1
user2,password2
...,...
user50, password50
In JMeter, when I run my test case, each thread will consume 1 record of the CSV file in parallel. By that I mean, Thread 1 takes the first record (user1,password1), Thread 2 takes the second record (user2,password2), until the last record (50 in this example). And all of that happens at the same time.
I am still new to JMeter and I would like to know if this is something that is "doable" through this tool. If it is possible, your help is greatly appreciated! :)
Given default CSV Data Set Config setup which looks like:
- each thread (virtual user) will take next line of the CSV file on each loop (iteration)
- when the last line of the CSV file will be reached it will start over from the beginning
With regards to your "at the same time" requirement - the load pattern is controlled by Thread Group settings (number of threads, loops, ramp-up period), depending on your setup you will have concurrency from 0 to 50 active users, you can observe it using i.e. Active Threads Over Time listener
If you want to send 50 requests at exactly the same moment - consider using Synchronizing Timer
