关于rails 3.1 cucumber-rails 1.2.0

在rails 2里叫cucumber
在rails 3里叫cucumber-rails

cucumber-rails 1.0.6升级后（当前1.2.0），就没有了web_steps 和selector support 还有path support

作者的用意是好的，怕因为这个限定或影响了自己cucumber的发挥

同时呢，也少了一个很不错的feature:install，之前scaffold之后会用来生成对应的，cucumber测试，就像是现在rspec和factory_girl可以做默认框架


总之，我没有好办法就把这几个文件又找回来啦，如下，大家情况不知道，我自己还比较习惯用一些订制好了的step的，convention了。

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

    when /^the home\s?page$/
      '/'

    # Add more mappings here.
    # Here is an example that pulls values out of the Regexp:
    #
    #   when /^(.*)'s profile page$/i
    #     user_profile_path(User.find_by_login($1))

    else
      begin
        page_name =~ /^the (.*) page$/
        path_components = $1.split(/\s+/)
        self.send(path_components.push('path').join('_').to_sym)
      rescue NoMethodError, ArgumentError
        raise "Can't find mapping from \"#{page_name}\" to a path.\n" +
          "Now, go and add a mapping in #{__FILE__}"
      end
    end
  end
end

module HtmlSelectorsHelpers
  # Maps a name to a selector. Used primarily by the
  #
  #   When /^(.+) within (.+)$/ do |step, scope|
  #
  # step definitions in web_steps.rb
  #
  def selector_for(locator)
    case locator

    when "the page"
      "html > body"

    # Add more mappings here.
    # Here is an example that pulls values out of the Regexp:
    #
    #  when /^the (notice|error|info) flash$/
    #    ".flash.#{$1}"

    # You can also return an array to use a different selector
    # type, like:
    #
    #  when /the header/
    #    [:xpath, "//header"]

    # This allows you to provide a quoted selector as the scope
    # for "within" steps as was previously the default for the
    # web steps:
    when /^"(.+)"$/
      $1

    else
      raise "Can't find mapping from \"#{locator}\" to a selector.\n" +
        "Now, go and add a mapping in #{__FILE__}"
    end

# TL;DR: YOU SHOULD DELETE THIS FILE
#
# This file was generated by Cucumber-Rails and is only here to get you a head start
# These step definitions are thin wrappers around the Capybara/Webrat API that lets you
# visit pages, interact with widgets and make assertions about page content.
#
# If you use these step definitions as basis for your features you will quickly end up
# with features that are:
#
# * Hard to maintain
# * Verbose to read
#
# A much better approach is to write your own higher level step definitions, following
# the advice in the following blog posts:
#
# * http://benmabey.com/2008/05/19/imperative-vs-declarative-scenarios-in-user-stories.html
# * http://dannorth.net/2011/01/31/whose-domain-is-it-anyway/
