设置默认下载目录和无头chrome

Question

我有一个rails应用程序,正在运行capybara和selenium,并使用chrome进行端到端测试.我想在运行chrome headless时设置默认下载目录.

以下是我在support/env.rb中设置的方法:

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

Capybara.register_driver :headless_chrome do |app|
capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
  'chromeOptions' =>  {
    'args' => %w(headless disable-gpu window-size=1920,1080),
    'prefs' => {
      'download.default_directory' => DownloadHelpers::PATH.to_s
    }
  }
)
Capybara::Selenium::Driver.new app,
  browser: :chrome,
  #args: ["--window-size=1024,768"], #UNCOMMENT TO HAVE BROWSER WINDOW POP UP
  desired_capabilities: capabilities
end

我注意到,如果我离开

'args' => %w(headless disable-gpu window-size=1920,1080)

然后设置默认下载目录,但是,浏览器会自动弹出,我要禁用它.

当我有两个:

    'args' => %w(headless disable-gpu window-size=1920,1080),
'prefs' => {
  'download.default_directory' => DownloadHelpers::PATH.to_s
}

它运行无头,但未设置默认下载路径.

我有以下版本:

水豚(2.14.2)

selenium-webdriver(3.6.0)

chromedriver-helper(1.1.0)

我使用了https://bugs.chromium.org/p/chromium/issues/detail?id=696481#c78和

将我的设置更改为:

Capybara.register_driver :selenium do |app|
  options = Selenium::WebDriver::Chrome::Options.new

  options.add_argument('--headless')
  options.add_argument('--no-sandbox')
  options.add_argument('--disable-gpu')
  options.add_argument('--disable-popup-blocking')
  options.add_argument('--window-size=1366,768')

  options.add_preference(:download, directory_upgrade: true,
                                prompt_for_download: false,
                                default_directory: 
 '/User/paulo/projects/app/tmp')

  options.add_preference(:browser, set_download_behavior: { behavior: 'allow' })

  driver = Capybara::Selenium::Driver.new(app, browser: :chrome, options: options)

  bridge = driver.browser.send(:bridge)

  path = '/session/:session_id/chromium/send_command'
  path[':session_id'] = bridge.session_id

  bridge.http.call(:post, path, cmd: 'Page.setDownloadBehavior',
                                params: {
                                  behavior: 'allow',
                                  downloadPath: '/User/paulo/projects/app/tmp'
                            })

  driver
end

请注意,您必须输入自己的downloadPath.
