黄瓜因错误未定义方法“访问"而失败 [英] Cucumber fails with error undefined method `visit'

问题描述

运行

rake cucumber 

甚至可以通过未经测试的功能.运行时

passes even untested features. while running

cucumber features/something.feature

抛出

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

我已经用谷歌搜索了一些 github 问题，他们谈论它但没有缓解.这在使用url参数时在没有机架的情况下运行Capybara会产生错误 很有帮助，但没有解决我的问题

I have googled some github issues where they talk about it but to no relief. This Running Capybara without rack produces errors when using url parameters was helpful but didn't resovle my issue

更新我确实从水豚 readme

水豚与黄瓜一起使用

cucumber-rails gem 内置了对 Capybara 的支持.如果你没有使用 Rails，手动加载 capybara/cucumber 模块:

The cucumber-rails gem comes with Capybara support built-in. If you are not using Rails, manually load the capybara/cucumber module:

require 'capybara/cucumber' 
Capybara.app = MyRackApp

但是在哪个文件中包含上述内容?我尝试将上述内容添加到 env.rb 并收到此错误:

But in which file to include the above? I tried adding the above to env.rb and got this error:

未初始化的常量 ActionController (NameError)

uninitialized constant ActionController (NameError)

现在评论后，我仍然得到同样的错误.

Now after commenting it, I still get the same error.

这是gemfile:

source 'https://rubygems.org'

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

#add cucumber

  #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

这里是 spec/spec_helper.rb(截断)

Here is spec/spec_helper.rb (truncated)

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

这里是 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

愿这个答案能帮助一些迷失的灵魂.

May this answer help some lost soul.

终于在这里得到了答案:黄瓜无头xvfb ubuntu

Finally got the answer here: Cucumber headless xvfb ubuntu

对于任何想要进行无头浏览的人来说，这救了我:

For anyone wanting to do headless browsing, this rescued me:

在 env.rb 中包含以下内容:

Included following in env.rb:

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:

headless is a relative rb file 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 features/support 文件夹中

Both env.rb and headless.rb are in features/support folder

我能够进行 bdd 和网络测试.

I am able to to do bdd and web testing.
