Question

正在运行

rake cucumber

甚至通过未经测试的功能。在跑步时

cucumber features/something.feature

抛出

undefined method `visit' for #<Object:0x00000001b13950> (NoMethodError)

我已经搜索了一些github问题，他们谈论它但没有解脱。这个Running Capybara without rack produces errors when using url parameters很有帮助，但没有解决我的问题

更新我确实从capybara readme

触及了以下内容

使用Capybara和黄瓜

cuc-rails gem内置了Capybara支持。如果你   没有使用Rails，手动加载水豚/黄瓜模块：
require 'capybara/cucumber' 
Capybara.app = MyRackApp

但是在哪个文件中包含以上内容？我尝试将上面的内容添加到env.rb并收到此错误：

未初始化的常量ActionController（NameError）

现在评论之后，我仍然得到同样的错误。

这是gemfile：

source 'https://rubygems.org'

#add dependency
gem 'diff-lcs', ">= 1.2.0"
gem 'rspec-expectations', "~> 3.0.0"

#add cucumber
group :test do
  gem 'cucumber-rails', :require => false
  # database_cleaner is not required, but highly recommended
  #gem 'database_cleaner', "~> 1.2.0"
  gem 'database_cleaner'
end

#add rspec
group :development, :test do
  gem 'rspec-rails', '~> 3.0'
  gem "capybara"
  gem 'factory_girl_rails'
  gem 'watir-webdriver'
  gem 'selenium-webdriver', '2.35.0'
  gem 'rubyzip'
  gem 'zip-zip'
end

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0',          group: :doc

# Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
gem 'spring',        group: :development

这是spec / spec_helper.rb（截断）

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'capybara'
include Capybara::DSL # Adding this line solved the error
require 'rspec/rails'
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
ActiveRecord::Migration.maintain_test_schema!
RSpec.configure do |config|
  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"
  config.infer_spec_type_from_file_location!
  config.include Capybara::DSL
end

这是env.rb

require 'capybara'
require 'capybara/dsl'
require 'capybara/cucumber'
#require 'capybara/rails'
#require 'capybara/session'
ActionController::Base.allow_rescue = false
begin
  DatabaseCleaner.strategy = :transaction
rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end
Cucumber::Rails::Database.javascript_strategy = :truncation

愿这个答案帮助一些失去的灵魂。

最后得到了答案：Cucumber headless xvfb ubuntu

对于任何想要无头浏览的人来说，这救了我：

env.rb中包含以下内容：

require 'capybara'
require 'capybara/cucumber'
require 'cucumber/rails'
require 'capybara/rails'
require 'capybara/dsl'

require 'selenium/webdriver'



$port = <port_number>

#Capybara.app_host = '<localhost>:<port>'
Capybara.configure do |config|
  config.run_server = true
  #Capybara.default_host = "<localhost>:<port>"
  config.default_driver = :selenium
  #config.app = "make sure this isn't nil"
  config.app_host = "<hostname>:#{$port.to_s}"
  config.server_port = $port
end

#To add chrome webdriver do the following in your machine
#chmod +x chromedriver
#sudo mv chromedriver /usr/local/share/
#sudo ln -s /usr/local/share/chromedriver /usr/local/bin/chromedriver
#sudo ln -s /usr/local/share/chromedriver /usr/bin/chromedriver
#Register chrome as default Capybara webdriver
Capybara.register_driver :firefox do |app|
  # optional
  client = Selenium::WebDriver::Remote::Http::Default.new
  # optional
  #client.timeout = 120
  Capybara::Selenium::Driver.new(app, :browser => :firefox, :http_client => client)
end
#set default js driver
Capybara.javascript_driver = :firefox

#Include headless
require_relative 'headless'

headless是一个相对的rb文件headless.rb：

if Capybara.current_driver == :selenium || Capybara.default_driver == :selenium
  require 'headless'

  headless = Headless.new
  headless.start

  at_exit do
    headless.destroy
  end
end

env.rb和headless.rb都在feature / support文件夹中

我可以进行bdd和网络测试。
