Hi all, i am very new when it comes to writing tests, can anyone give me an idea how to write RSpec test for the following custom validation.

def validate_campaign_and_ad     unless self.ad.nil? || self.ad.campaign_id == self.campaign_id       errors.add(:campaign_id, "ad.campaign (#{self.ad.campaign_id}) does not match campaign (#{self.campaign_id})")     end   end

Thanks in Advance

I'd start by constructing an object that should pass the validation and checking that some_object.should be_valid? and then by constructing an object that isn't valid and checking that the object isn't valid and that the right error message is present.
