Topic: Unit testing without a database

I've been trying to figure out how to do this for days now, so excuse me if I missed something that already answers this.

I've got a rails application that I'm developing and it doesn't have or need a database.  I'm working with Ruby 1.8.7 p249 and Rails 2.3.2.

I've uncommented the line in environment.rb that is supposed to work for disabling the database:

config.frameworks -= [ :active_record, :active_resource, :action_mailer ]

When I try to run:

rake test:units

I get the following error:

ActiveRecord::ConnectionNotEstablished

I've tried various things that I've read online but none of them seem to work.

This includes commenting out "config.whiny_nils = true" in the test.rb in environments.

I've followed the instructions in this document:

http://media.pragprog.com/titles/fr_rr/NoDatabase.pdf

But I really think that it's for a very old version of Rails.

I've looked through test_help.rb in rails, and I'm wondering if ActiveRecord is still being defined despite me removing it from the frameworks.

I think I've got a pretty good handle on ruby in general, but I don't particularly understand exactly how the whole rake system works.

At any rate, any help would be greatly appreciated, thanks.

Also, I can't post my code but I'll do my best to answer any follow up questions.

Thanks in advance.
