I am trying to create a load test for a financial app (.Net). This is an app that requires you to login and you cannot have 2 people logged in with the same login. I am using a recorded web test that logs in as as one user. When I use this web test in my load test, how will VS handle the concurrent users for this web test? Will it try use this same login for each concurrent user in my load test? I am using VS 2008. I am not sure if this is the cause of the numerous errors I encounter for I try to run the load test.
There will likely be configuration issues with the LoadTest to reduce the likelyhood of using one of the logins more than once. One way to get around this would be to put lots of user records in the database.
