Chrome版本：59.0.3071.104
使用Cucumber,Capybara,Selenium实现无头Chrome的自动化测试.
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
在进行黄瓜测试时,它说：
WARN Selenium [DEPRECATION] :args or :switches is deprecated. Use
Selenium::WebDriver::Chrome::Options#add_argument instead.
使用Headless Chrome的水豚和硒的正确方法是什么？谢谢.
编辑1：我使用Ruby-Binding,Capybara和Working Example尝试了以下操作.但它也给出了错误.
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ChromeDriver Capabilities& Chrome Command Line Switches我收到一个错误.
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,desired_capabilities: caps
)
end
Capybara.default_driver = :selenium_chrome
解决方法
1)确保你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,它以旧方式使用args,这就是我收到警告的原因.
2)确保你在Linux上有Chrome版本57,在macOS上有59或在Windows上有60;
3)添加/更新gem selenium-webdriver;
4)将以下驱动程序添加到spec_helper.rb或rails_helper.rb：
Capybara.register_driver :chrome do |app| Capybara::Selenium::Driver.new app,options: Selenium::WebDriver::Chrome::Options.new(args: %w[headless disable-gpu]) end Capybara.javascript_driver = :chrome
