硒浏览器何时自动死亡？

Question

我们创建了许多使用硒的测试套件。当我们单独执行它们时，它们都成功运行。但是，当我们尝试运行整个套件时，浏览器随机死亡，我们收到以下错误消息。

据我所知，代码中没有错误。因此，请让我知道，在什么情况下硒网格自动杀死浏览器。

Answer 1

Error communicating with the remote browser. It may have died.此错误来自某些原因。

1）意外的是浏览器在一段时间后会关闭或者你的网格机器也会这样做。

2）driver.close();在完成执行之前调用。

• 可能是你在课后写driver.close();。

3）driver.quite();也有同样的问题，因为2点

4）请检查您的驱动程序实例启动处处完美。
