Hi,

I searched in the group for a solution but I haven’t found one so post the question here.

I have a csv file with 50,000 rows, and with header such as ID NAME.

My load test needs in each session, to randomly pick 10 rows, to add them into a collection such as Array of Maps, them use the Array of Maps to construct my request body for the POST call.

I know how to get one row randomly from the feeder but don’t know how to get 10 rows randomly for each session.

Any sample code to do it?

Thanks.

Eric
