Jmeter random requests

Question

I want to test a web application. Lets say that i have a php script that i want to test

www.example.com/jmeter.php?runtest=??

The jmeter.php with method GET reads an id that refers to each test! I have all my ids to a csv file and i read them with the CSV data set config.

CSV file
8
9
10

If i set the number of threads (users) to 3 i get 3 requests BUT is the same request!

www.example.com/jmeter.php?runtest=8
www.example.com/jmeter.php?runtest=8
www.example.com/jmeter.php?runtest=8

What i want? The following:

www.example.com/jmeter.php?runtest=8
www.example.com/jmeter.php?runtest=9
www.example.com/jmeter.php?runtest=10

Any ideas? Thanks!

Answer 1

Though this was not available at the time this question was originally asked, there is now the Random CSV Data Set Config plugin which is available for JMeter. It accomplishes exactly what the original question asks, which is to select values from rows at random from a CSV source file.

You can set your CSV data source file using the "Filename" parameter, and when the "Random order" box is checked, rows will be read in random order instead of sequentially:

This can be added to your JMeter test plan though the Plugins Manager from the Options menu:

The Random CSV Data Set Config element is one of the most popular plugins in use today that is often overlooked by new test designers, as it must be first enabled though the Plugins Manager as described above.
