You probably want to have a look at acts_as_fu gem: https://github.com/nakajima/acts_as_fu.
Btw, you can use db in your rspec tests, but you don;t want to do this to test extensions.
Question
I'm creating a Ruby gem that will extend the ActiveRecord functionality. I read the following Stack Overflow posts of how to extend ActiveRecord: post 1, post 2.
I'm using rspec for testing as describe in this great tutorial.
My question is, how do I test my active record extension methods using Rspec, because as I can think, we are not using a DB to save records.
How can I write tests for these kind of gems?

if you didn't come up with a solution yet I was struggling with the same issues and and eventually came across this tutorial. It uses a really solid approach and works like a dream.
Basically, it involves referencing an active record file in the test helper which your test itself creates from a schema and seed file.
This approach was surprisingly simple to implement and helped me better understand how ActiveRecord extensions worked. So cheers Ryan!
Hope it helps.
