The folks here have given me the task of figuring out if cucumber can
be used successfully to test some of our apps.

I have the latest versions of rails, mechanize, cucumber webrat and
rspec installed.

  Feature: New PC
  In order to get a sweet new PC
  As a apple nerd
  I want to find

  Scenario: Get a sweet new computer
  Given I visit ""
  When I fill in "q" with "apple"
  And I press "Google Search"
  Then I should see ""

  Webrat.configure do |config|
    config.mode = :mechanize
  class MechanizeWorld < Webrat::MechanizeSession
    require 'spec'
    include Spec::Matchers

module NavigationHelpers
  # Maps a name to a path. Used by the
  #   When /^I go to (.+)$/ do |page_name|
  # step definition in webrat_steps.rb
  def path_to(page_name)
    case page_name

    when /the homepage/

    # Add more mappings here.
    # Here is a more fancy example:
    #   when /^(.*)'s profile page$/i
    #     user_profile_path(User.find_by_login($1))

      raise "Can't find mapping from \"#{page_name}\" to a path.\n" +
        "Now, go and add a mapping in #{__FILE__}"
This is not complete however. If I run rake features at this point, I
get an error saying it doesn't understand the visit command in the
step (which i assume comes from Mechanize)

The various information around the internet points to me needing to
add this to the world:
[code=]World do
Adding this block gives me the following error:
step_mother.rb:195:in `World': You can only pass a pro
c to #World once, but it's happening (Cucumber::MultipleWorld)
in 2 places:
ls/world.rb:84:in `World'
features/support/paths.rb:26:in `World'
Use Ruby modules instead to extend your worlds. See the
Cucumber::StepMother#World RDoc

rake aborted!
Command failed with status (1): [c:/ruby/bin/ruby -I "c:/ruby/lib/ruby/
(See full trace by running task with --trace)

So if I have to use a module to extend the world (even though the
documentation seems to point at this being right) how do I go about
doing this?
