action helper for rspec

action.rb

# 
# Put this file into spec/support/ folder.
#
# Helper +action+ allows you to write something like
#
# describe "GET index" do
#   action { get :index }
#
#   context 'if user signed in' do
#     before { sign_in user }
#     it { should respond_with :success }
#   end
#
#   context 'if user signed out' do
#     it { should redirect_to sign_in_path }
#   end
# end
#
# instead of
#
# describe "GET index" do
#   context 'if user signed in' do
#     before { sign_in user }
#     before { get :index }
#     it { should respond_with :success }
#   end
#
#   context 'if user signed out' do
#     before { get :index }
#     it { should redirect_to sign_in_path }
#   end
# end


def action(&block)
  before { self.class.before(&block) unless action_added?(&block) }
end

def action_added?(&block)
  self.class.hooks[:before][:each].map(&:to_proc).include? block
end

btw, it's a gem https://rubygems.org/gems/rspec-action :)
