我有： Jenkins，Selenium Server Standalone 3.11.0，Chrome 65.0.3325.146和Chromedriver 2.36.540471。
问题：由于我的一天测试开始在Jenkins上失败并出现以下错误：“WebDriverError：未知错误：未知会话” - 本地工作没有任何问题。
以下是Jenkins的控制台输出：

在这个测试中，我试图访问网站（它是一个PWA）并通过表单发送一些数据 - 根据截图测试在表单模态打开时挂起。令我感到非常困惑的是，我在其他测试中使用相同的方法进行数据发送，这些测试正在通过......
解决方案：本地Chrome更新（至第65版）让我可以查看有问题的测试期间发生了什么 - 推送通知弹出正在中断表单填写。我在配置中将其关闭并再次进行测试。
