Why are you trying to avoid hitting the database?  I would imagine
that avoiding the database makes it hard to test much of anything.

If the general problem is that you can't have a test database on your
real database server, and can't install your own instance of it,
sqlite is really easy to set up
(http://wiki.rubyonrails.org/rails/pages/HowtoUseSQLite).

If you need to do this for just this one test you could close the
connection (eg. user.connection.disconnect!) and possibly reopen it
after if you need it again (reconnect!).
