Specifying user names for load test
We have a web app that uses forms authentication. Each user can only be logged in once. If you try to log in with the same user name again, you get kicked off. What is the best way to handle load testing in such a scenario?
I don't really want to write a separate test for each user. Data-driven testing doesn't work here, as it calls the test sequentially for each row in the database. Is there some way to specify at the load test level that I want to simulate 200 users and that I want user1 to be X, user2 to be Y, etc.
The only thing I found at that level is the number of users you want to simulate and how you want to generate the load (constant, step, ...). There was no way to specify user names outside of the actual test level, which doesn't solve my problem.
Thanks.
