Very basic test suite using Watir to ensure a Drupal site is working

drupal.rb

#!/usr/bin/ruby1.9.1
require "rubygems"
require "test/unit"
require "watir"
$site = ARGV[0]
puts $site
if ($site[-1,1] != "/")
	puts "url must end in a slash"
	exit
end

		assert_equal(browser.h2(:index, 1).text, "Access denied")
		browser.close

		browser = Watir::Browser.start($site)
		number_errors = browser.contains_text("error:")
