Mocks and Associations

Hi List,

I am doing some testing which involves an authentication method on my
user controller. In production it actually uses PAM (on my linux system
to an external LDAP server) to authenticate users but this is
impractical for my testing. To get to the point I have:

require 'pam'

class User < ActiveRecord::Base
  has_many :blah

  def authenticate(password)
    # some pam voodoo here
  end
end

In my test/mocks/test directory I have:

require 'models/user'

class User < ActiveRecord::Base
  def authenticate(pass)
    pass == Digest::MD5.hexdigest(self.password)
  end
end

However, whenever I run this test my associations fail. Does anyone
have any suggestions?

Regards,

Daniel
