title: NameError: uninitialized constant Capybara::Webkit.configure
body: <p>I must not be understanding correctly where to place this method call. I have this <code>test_helper.rb</code> file</p>
  
  <pre><code>ENV['RAILS_ENV'] ||= 'test'
  require File.expand_path('../../config/environment', __FILE__)
  
  require 'rails/test_help'
  require 'minitest/rails/capybara'
  require 'capybara'
  require 'capybara/rails'
  require 'capybara/webkit'
  
  Dir[Rails.root.join('test/support/**/*.rb')].each { |f| require f }
  
  Capybara::Webkit.configure do |config|
    config.allow_unknown_urls
  end
  </code></pre>
  
  <p>And I get this error when I run <code>rake test</code></p>
  
  <p>NoMethodError: undefined method <code>configure' for Capybara::Webkit:Module
  /Users/sameer/code/rails/door_app/test/test_helper.rb:XX:in</code>'</p>
  
  <p>It seems like I'm doing what's described in the README at the Capybara-webkit Github page.</p>
