这是一个片段,用于防止警告出现在控制台中:https: //github.com/thoughtbot/capybara-webkit/issues/157.

Capybara::Webkit.configure do |config|
  config.block_unknown_urls  # <--- this configuration would be lost if you didn't use .merge below
end

class WebkitStderrWithQtPluginMessagesSuppressed
  IGNOREABLE = Regexp.new( [
    'CoreText performance',
    'userSpaceScaleFactor',
    'Internet Plug-Ins',
    'is implemented in bo'
  ].join('|') )

  def write(message)
    if message =~ IGNOREABLE
      0
    else
      puts(message)
      1
    end
  end
end

Capybara.register_driver :webkit_with_qt_plugin_messages_suppressed do |app|
  Capybara::Webkit::Driver.new(
    app,
    Capybara::Webkit::Configuration.to_hash.merge(  # <------ maintain configuration set in Capybara::Webkit.configure block
      stderr: WebkitStderrWithQtPluginMessagesSuppressed.new
    )
  )
end

Capybara.javascript_driver = :webkit_with_qt_plugin_messages_suppressed

虽然这可以隐藏消息,但我觉得修复它的正确方法是防止加载插件.但我还没想出如何用Capybara和webkit做到这一点.
