How to test identical behavior without being redundant?

I’ve got many models that have this declared:
has_many :notifications, :as => :notifiable, :dependent => :destroy

… And so I have many model specs such as:

describe Reply do

it “should eliminate any associated notification records when
destroyed” do
reply = create_reply
reply.notifications.should_not be_blank

reply.destroy
reply.notifications.reload.should be_blank

end

end

describe Post do

it “should eliminate any associated notification records when
destroyed” do
post = create_post
post.notifications.should_not be_blank

post.destroy
post.notifications.reload.should be_blank

end

end

etc…

Is there an ideal way to dynamically generate this for any models that
respond
to notificaions so that I don’t have redundant noisy tests?

Thanks.
