I am able to run Load test on my website using single login and running 200 concurrent users in VS 2013 ultimate version.
What I would like to do is instead of single login/password, I want to have 200 different login/pass so test can pick up each user randomly and use that login to perform the test. How do I do that?
How do I tell web performance test to use predefined 200 login/pass and use new user for each test it runs simultaneously.
