Rails LocalJumpError: pas de bloc donné (rendement) - ruby-on-rails, ruby

Beaucoup de mes spécifications me donnent l’erreur ci-dessus mais je ne sais pas pourquoi.?

# Model
describe Notification do
context "has valid db fields" do
subject { Factory.build(:notification)}
it { should be_valid }
it { should have_column(:title).with_options(:null => false, :type => :string)}
it { should have_column(:content).with_options(:null => false, :type => :string)}
it { should have_column(:sent_at).with_options(:type => :date)}
it { should have_column(:created_at).with_options(:null => false, :type => :date)}
it { should have_column(:updated_at).with_options(:null => false, :type => :date)}
end
end

Je pense que c'était en fait dû au fait de ne pas avoir "shoulda" dans mon Gemfile pour les adaptateurs personnalisés!
