how to emulate parallel multi-user usability testing with django and selenium/grid?

[Tony Schmidt]

I can get my Selenium tests running fine for one user/ sequentially on Django 1.4 using LiveServerTestCase, but I would like to emulate parallel multi-user testing. I don't think I need real load testing, since my apps are mostly moderate/low traffic web-sites and internal web-apps, so I would prefer to avoid extra tools like JMeter.

I've started out setting up Selenium Grid but am not sure how to keep my tests independent and still run multiple tests with multiple users. I assume the test cases should be run for different users on the same DB simultaneously - but each test drops and creates a new DB, so I don't understand how that is possible.

And I don't want to sign up for a service like BrowserMob.
