Need to debug a failed cucumber scenario? Try this.

open_browser_on_fail.rb

=begin
From http://jonkinney.com/articles/2010/04/21/using-save_and_open_page-to-open-failed-cucumber-scenerios-in-a-browser-with-images-and-css/
I chose to put this code in a file under the features/support directory called: open_browser_on_fail.rb. If it's sitting next to the env.rb file itself then you have the new file in the right place.

Place the following code in that file and you'll be good to go!
=end
After do |scenario|  
  if scenario.status == :failed
   save_and_open_page
  end  
end

module Webrat
 module SaveAndOpenPage
   def save_and_open_page
    return unless File.exist?(Webrat.configuration.saved_pages_dir)
    
    filename = "#{Webrat.configuration.saved_pages_dir}/webrat-#{Time.now.to_i}.html"
    
    File.open(filename, "w") do |f|
      f.write rewrite_public_file_references(response_body)
    end
    
    open_in_browser(filename)
  end
  
  def rewrite_public_file_references(response_html)
    # remove conditional comments/ie stylesheets
    response_html.gsub!(/<!--\[.*?\]-->/im, '')
    # remove other stylesheets
    response_html.gsub!(/<link href=(.*)\/>/i, '')
    
    response_html.gsub!(/("|')\/(stylesheets|images|javascripts)/, '\1' + '../public' + '/\2')
    
    response_html.gsub!(/<\/head>/i, "<style>#{rewrite_public_stylesheet_image_references('\/images', '../public')}<\/style>\n<\/head>")
  end
  
  def rewrite_public_stylesheet_image_references(regex, server_url)
    dir = "/Users/jkinney/Sites/Rails/Client/new_rails_app/public/stylesheets/"
    
    stylesheets = %w(reset admin main js_menu css_tabs firefox)
    
    css = ""
    stylesheets.each do |file|
      # puts file
      lines = []
      File.open(dir+file+".css", "r"){|f| lines = f.readlines }
      lines = lines.inject([]){|l, line| l << line.gsub(/#{regex}/i, "#{server_url}/images")}
      css << lines.to_s
    end
    css
