如何与水豚和硒一起使用无头铬 [英] How to use headless chrome with capybara and selenium

问题描述

Chrome版本：59.0.3071.104

Chrome version: 59.0.3071.104

使用Cucumber，Capybara，Selenium来实现无头Chrome的自动化测试。

Using Cucumber, Capybara, Selenium to implement automation testing with Headless Chrome.

功能/支持/env.rb

features/support/env.rb

require 'rubygems'
require 'capybara/cucumber'

Capybara.register_driver :selenium_chrome do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome, args: ['headless'])
end

Capybara.default_driver = :selenium_chrome

运行黄瓜测试时，它说：

When running a cucumber test, it says:

WARN Selenium [DEPRECATION]：args或：switches已过时。改用
Selenium :: WebDriver :: Chrome :: Options＃add_argument。

WARN Selenium [DEPRECATION] :args or :switches is deprecated. Use Selenium::WebDriver::Chrome::Options#add_argument instead.

使用水豚的正确方法是什么和硒与无头铬。谢谢。

What is the correct way to use capybara and selenium with Headless Chrome. Thank you.

编辑1：我尝试使用 Ruby绑定，水豚和工作示例。

EDIT 1: I tried the following using Ruby-Binding, Capybara and Working Example. But it gives errors as well.

require 'rubygems'
require 'capybara/cucumber'
require 'selenium-webdriver'

Capybara.register_driver :selenium_chrome do |app|
  options = Selenium::WebDriver::Chrome::Options.new
  options.add_argument('--headless')
  driver = Selenium::WebDriver.for :chrome, options: options
  Capybara::Selenium::Driver.new(
    app, 
    browser: :chrome, 
    desired_capabilities: driver
  )
end

Capybara.default_driver = :selenium_chrome

错误：

> undefined method `each' for
> #<Selenium::WebDriver::Remote::Capabilities:0xd13baac> (NoMethodError)

编辑2：
下载最新的 ChromeDriver 2.30

使用中的示例href = https://sites.google.com/a/chromium.org/chromedriver/capabilities rel = noreferrer> ChromeDriver功能& Chrome命令行开关出现错误。

Using the example from ChromeDriver Capabilities & Chrome Command Line Switches I get an error.

Net :: ReadTimeout（Net :: ReadTimeout）

Net::ReadTimeout (Net::ReadTimeout)

require 'rubygems'
require 'capybara/cucumber'
require 'selenium-webdriver'

Capybara.register_driver :selenium_chrome do |app|
  caps = Selenium::WebDriver::Remote::Capabilities.chrome(
    "chromeOptions" => {
      "binary" => "/chromedriver_win32/chromedriver.exe",
      "args" => [ "--disable-web-security", "--headless" ]
    }
  )  
  Capybara::Selenium::Driver.new(
    app, 
    browser: :chrome, 
    desired_capabilities: caps
  )
end

Capybara.default_driver = :selenium_chrome

推荐答案

1）确保您没有其他注册的驱动程序，我自己犯了这个错误，并且有一个 iphone 驱动程序，该驱动程序以旧方式使用了 args ，这就是为什么我得到

1) Make sure you don't have another registered driver, I made this mistake myself and had an iphone driver, which was using the args in the old way, that's why I was getting the warning.

2）确保在Linux上具有Chrome版本 57 + ，在MacOS上具有 59 + 在Windows上为 60 + ；

2) Make sure you have Chrome version 57+ on Linux, 59+ on macOS or 60+ on Windows;

3）添加/更新gem selenium-webdriver ;

3) Add/update the gem selenium-webdriver;

4）添加以下 driver 到您的 spec_helper.rb 或 rails_helper.rb ：

4) Add the following driver to your spec_helper.rb or rails_helper.rb:

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new app, browser: :chrome,
    options: Selenium::WebDriver::Chrome::Options.new(args: %w[headless disable-gpu])
end

Capybara.javascript_driver = :chrome
