ruby-on-rails-3 - cucumber step_definitions中的未定义Webrat方法

Question

当我运行功能时，出现此错误:

undefined method `visit' for #<Cucumber::Rails::World:0x81b17ac0> (NoMethodError)

这是我的Gemfile的相关部分。

group :development, :test do
  gem "rspec-rails", ">= 2.0.0.beta.19"
  gem "cucumber"
  gem "cucumber-rails", ">= 0.3.2"
  gem 'webrat', ">= 0.7.2.beta.1"
end

相关的step_definition(尽管我不认为这很重要)

When /^I create a movie Caddyshack in the Comendy genre$/ do
  visit movies_path
  click_link "Add Movie"
  fill_in "Title", :with => "Caddyshack"
  check "Comedy"
  click_button "Save"
end

在env.rb中，我具有以下Webrat配置:

# […]
require 'webrat'
require 'webrat/core/matchers'

Webrat.configure do |config|
  config.mode = :rails
  config.open_error_files = false # Set to true if you want error pages to pop up in the browser
end
# […]

我在这里想念什么吗？

Answer 1

我不得不将config.mode设置为:rack而不是:rails:

# […]
require 'webrat'
require 'webrat/core/matchers'

Webrat.configure do |config|
  config.mode = :rack
  config.open_error_files = false # Set to true if you want error pages to pop up in the browser
end
# […]

现在可以正常工作了。
