java - selenium 浏览器什么时候自动死掉？

Question

我们已经使用 selenium 创建了许多测试套件。当我们单独执行它们时，它们都运行成功。但是，当我们尝试运行整个套件时，浏览器会随机死机，我们会收到以下错误消息。

org.openqa.selenium.WebDriverException: Error communicating with the remote browser. It may have died.

据我所知，代码中没有错误。因此，请让我知道，在什么情况下，selenium 网格会自动终止浏览器。

Answer 1

与远程浏览器通信时出错。它可能已经死了。这个错误是由于某些原因造成的。

1) 浏览器在一段时间后意外关闭，或者您的网格机器也会这样做。

2) driver.close(); 在执行完成之前调用。

• 你可以在课后写 driver.close();。

3) driver.quite(); 也有和第2点一样的问题。

4) 还请检查您的驱动程序实例在任何地方都完美启动。
