chromedriver不使用download.defaultDirectory

Question

使用红宝石，硒，水豚，黄瓜；通过以下方式在env.rb中设置本地驱动程序：

args = %w[--ignore-certificate-errors --window-size=1360,998]
prefs = {
      download: {
          default_directory: "#{Directories::DATA}/downloads",
          directory_upgrade: true,
          prompt_for_download: false
      }}
opts = Selenium::WebDriver::Chrome::Options.new(args: args, prefs: prefs)

Capybara.register_driver :selenium_chrome do |app|
  Capybara::Selenium::Driver.new(app, browser: :remote,
                                 url: "http://localhost:9515",
                                 options: opts)
end

chromedriver.log说正确的绝对路径已添加到首选项，但测试仍下载到默认的Downloads文件夹，而不是chromeOptions中指定的路径

最新版本的chromedriver要求的设置有所不同。最简单的解决方案是像设置Capybara一样在Chrome测试中设置所有3种方式-https://github.com/teamcapybara/capybara/blob/44621209496fe4dd352709799a0061a80d97d562/spec/selenium_spec_chrome.rb#L13
