PhantomJS在JENKINS中间歇性抛出错误-连接被拒绝等

Question

我在Jenkins中断断续续地收到以下错误，最近的错误发布在下面。我以前从未见过这个问题。一些开发人员使用CSS3推送一些CSS更改，这就是我开始收到错误的时候。我正在使用phantomjs version - 1.9.8。有什么想法吗？

Connection refused - connect(2) for "127.0.0.1" port 8910 (Errno::ECONNREFUSED)

我假设您每次都会遇到这个错误，那么您需要在Jenkins上更新Selenium独立服务器。

如果您断断续续地遇到这个问题，那么您也可以尝试重新启动phantomjs

def restart_phantomjs
        puts "-> Restarting phantomjs: iterating through capybara sessions..."
        session_pool = Capybara.send('session_pool')
        session_pool.each do |mode,session|
          msg = "  => #{mode} -- "
          driver = session.driver
          if driver.is_a?(Capybara::Poltergeist::Driver)
            msg += "restarting"
            driver.restart
          else
            msg += "not poltergeist: #{driver.class}"
          end
          puts msg
        end
      end
      module_function :restart_phantomjs
 end
