I think this is more a problem of the master page.

You are seeing the naming containers.

I haven't used nUnitAsp in a while, but you should be able
to solve this the same way you test controls that are
inside other user controls.
You get "ctl00" from the masterpage, ContentPlaceHolder1
from the ContentPlaceHolder and the Login1 from the login
control.
