[mocha-developer] ActiveRecord Validations - validates_uniqueness_of

[Jonathan Younger]

Hello,

I'm wanting to use Mocha and Stubba for my tests in place of the  
default Rails testing with fixtures.

I have the following class:

class Person < ActiveRecord::Base
   validates_uniqueness_of :email
end

and am wondering how I can test to ensure that the  
validates_uniqueness_of validation is running.

Any ideas?
