ruby - Unable to obtain stable firefox connection in 60 seconds (127.0.0.1:7055) Selenium 3.6.0

问题描述

I am getting an Issue mentioned in subject, which is an intermittent one. However its making our CI CD pipelines unstable so thought to get some help from geeks available on this great platform.

Since this is an intermittent issue, I don't wish to upgrade my browser version, mentioning it as this comes mostly as the suggestion.

Here are details which may help you to identify the cause which I was not able to

What libraries I use -

gem 'selenium-webdriver', '3.6.0'
gem 'capybara', '2.18.0'
gem 'site_prism', '2.11'

What browser I use -

Firefox - 52.8.0

Which OS I use -

RHEL7

How do I configure my driver -

 firefox_profile = Selenium::WebDriver::Firefox::Profile.new
  firefox_profile['browser.download.dir'] = '/tmp'
  firefox_profile['browser.download.folderList'] = 2
  # content-type of file that will be downloaded
  firefox_profile['browser.helperApps.neverAsk.saveToDisk'] = 'application/json;application/octet-stream;application/csv;text/csv;application/zip;application/x-zip;application/x-zip-compressed;application/x-rpm;application/pdf;application/xml;application/x-x509-ca-cert'
  firefox_profile['timeout'] = 480000
  firefox_profile['pdfjs.disabled'] = true
  firefox_profile['resynchronization_timeout'] = 90
  firefox_profile['resynchronize '] = true
  firefox_profile['dom.max_chrome_script_run_time'] = 0
  firefox_profile['dom.max_script_run_time'] = 0

  Capybara.default_selector = :css
  Capybara.ignore_hidden_elements = true
  reset_wait_time
  Capybara.run_server = false
  client = Selenium::WebDriver::Remote::Http::Default.new
  client.timeout = 240

  if ENV['LOCAL'] == 'true'
    STDOUT.puts 'starting local run'
    Capybara.default_driver = :firefox
    Capybara.register_driver :firefox do |app|
      begin
        STDOUT.puts 'Attempting to create browser instance'
        Capybara::Selenium::Driver.new(app, browser: :firefox, profile: firefox_profile, marionette: false, http_client: client)
      rescue => e
        STDOUT.puts 'Error: Failed Attempting to create browser instance'
        STDOUT.puts e
        STDOUT.puts e.backtrace
      end
    end

    begin
      page.driver.browser.manage.window.resize_to(1200, 1200)
    rescue => e
      STDOUT.puts 'Error: Failed resize browser'
      STDOUT.puts e
      STDOUT.puts e.backtrace
    end
end

Error Stack Trace -

解决方案

我知道您说过您不想被告知更新您的浏览器版本，但解决方案确实会花时间更新您的所有测试 gem。你提到的每一个 gem 的版本都已经过时了，从那以后，所有提到的 gem 的稳定性和时间都得到了很多改进。

从技术上讲，您实际上正在运行的 Firefox 版本从未真正得到 Selenium 使用本机 Firefox 驱动程序的支持，因为那时 Selenium 已经开始专注于 WebDriver (geckodriver)。真正的解决方案是更新。
