RSpec like DSL in Test::Unit for acceptance testing.

I have project where I have to use Test::Unit. Fine, but I am used to RSpec DSL, especially when it comes to user stories (features). So, here is simple module that shows how you easily can use RSpec-like expressions in default testing framework.

	module Test::Unit::UserStory
	class UserStoryTestCase < ActionController::IntegrationTest
	class << self
	attr_accessor :description
	alias :it :test
	def criteria(name, options = {}, &block)
	klass = create_class(name, self, &block)
	helper_klass = options[:js] ? CapybaraJavascriptTestHelper : CapybaraTestHelper
	klass.send(:include, helper_klass)
	klass
	end
	def background(&block)
	define_method(:setup, &block)
	end
	end
	end
	def story(name, description, options = {}, &block)
	klass = create_class(name, UserStoryTestCase, &block)
	klass.description = description
	klass
	end
	def create_class(name, superclass, &block)
	klass = Class.new(superclass, &block)
	name = name.gsub(/(^\d*|\W)/, ' ').lstrip
	klass_name = name.gsub(/(^[a-z]|\s+[a-zA-Z])/).each do |match|
	match.lstrip.upcase
	end
	Object.const_set klass_name, klass
	end
	end

Just save that module in a file that will be required by your test helper and include in you test unit spec.

	require File.expand_path(File.dirname(__FILE__) + "/../test_helper")
	include Test::Unit::UserStory
	story "Create the thing", %{
	As a user
	I want to create something
	In order to show something
	} do
	criteria "without js when logged in" do
	it "does something"
	end
	criteria "when logged in", :js => true do
	background do
	login_as(:me)
	end
	it "should be easy to create"
	it "should be able to create something" do
	end
	end
	end

With Test::Unit::Feature you have a simple DSL. Soon we'll publish in on github as a gem. Now it works with Ruby 1.8.7 and Rails 2.3.10. I didn't test it with the latest stuff.

Done with Jorge :)
