rake test, disable rebuild of test database

Hi, I was wondering if someone knows of a good way to disable the rebuilding of the test database on each rake test execution. At this point I'd prefer just to run the tests I have against a copy of the production database. I'm using multiple databases and have quite a few tables and just don't see myself maintaining fixtures for all of these atm (atm really means never, I think. or atleast that's the way it ususally ends up :wink: ).

Not the rails way, I know, but I'm also dealing with a bunch of legacy tables and that's not the rails way either, but it works.

Thanks, Fredrik
