Updated code with cancan stubs

		defaults = {:action => :manage, :object => nil, :not_authorized_status => 403}.merge(args.extract_options!)
		options = defaults.merge(args.extract_options!)

		user = Factory.build(:user)
		user.stubs(:persisted?).returns(true)
    controller.stubs(:current_user).returns(user)

		authorize(options)
		action.call
		response.should_not return_status(options[:not_authorized_status])
		
		deauthorize(options)
		action.call
		response.should return_status(options[:not_authorized_status])
	end	

def authorize(options)
		controller.current_ability.stubs(:can?).with(options[:action], options[:object]).returns(true)
	end
	
	def deauthorize(options)
	 	controller.current_ability.stubs(:can?).with(options[:action], options[:object]).returns(false)
