I've googled for an answer to my question, and I've found similar questions, but not much guidance.
I've written a Test Plan that has a large amount of failures (150 threads with only 26 going through). We're thinking that perhaps if we use different users to login each time, it may increase the successes. I've read and heard that JMeter can use variables when logging into a form authenticated site. Currently, I have the username/password coded into the script but have no clue as to how I would pull in other username/password combinations. I have a total of 10 different users that I can loop through, and assume that 10 should be enough to seperate the sessions with the ramp up I'm using. Ideas?
