Testing Django Application

It is quiet simple to do unit test for a Django application.  The manage tool has a test command to run all unit tests in a Django application.  Developers only need write either doctests or unit tests!

OperationalError: table "auth_group_permissions" already exists

I got this error when I try to test my Django application at first time!  It took me a couple of hours time to figure out the reason: I create a module (folder) called auth, which is the same name with default django.contrib.auth module.  And there is a model class in that module.  Then the syncdb command got confused and try to create the table auth_group_permissions again!  Don't know why it works like that.  But after I change the module name to something else, such as myauth, then no such error any more!
