ruby – 使用headless_chrome模拟设备

我正在尝试在运行我的规范时模拟不同的设备,现在没有结果.

#spec_helper

require 'rspec'
require 'capybara'
require 'capybara/rspec'
require 'selenium/webdriver'

Capybara.register_driver :headless_chrome do |app|
 Capybara::Selenium::Driver.load_selenium
 browser_options = ::Selenium::WebDriver::Chrome::Options.new
 browser_options.args << '--headless'

 mobile_emulation = { "deviceName" => "iPhone 8" }
 capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
   "chromeOptions" => { "mobileEmulation" => mobile_emulation }
 )

 Capybara::Selenium::Driver.new(app,browser: :chrome,options: browser_options,desired_capabilities: capabilities)
end

我应该在选项而不是功能中包含mobile_emulation部分吗？

解决方法

chromeOptions不再是一个有效的密钥(它被goog：chromeOptions取代),但由于你已经使用了:: Selenium :: WebDriver :: Chrome :: Options类,你应该只使用add_emulation方法 – https://www.rubydoc.info/gems/selenium-webdriver/Selenium/WebDriver/Chrome/Options#add_emulation-instance_method.

browser_options = ::Selenium::WebDriver::Chrome::Options.new
browser_options.args << '--headless'
browser_options.add_emulation(device_name: 'iPhone 8')

Capybara::Selenium::Driver.new(app,options: browser_options)
