在 Grid 上运行时如何关闭 ChromeDriver?

问题描述

我目前正在通过 TestNG 套件使用带有 Selenium Grid 2 的 RemoteWebDriver 运行我的测试.这适用于 Firefox 和 IE.现在我添加了 Chrome 并且测试运行良好，但是在套件的所有测试之后调用 driver.quit() 时总是得到一个异常(适用于 FF 和 IE).

I am currently running my tests with RemoteWebDriver with Selenium Grid 2 through TestNG suites. This works fine with Firefox and IE. Now I added Chrome and the tests run fine, but I always get an Exception when calling driver.quit() after all tests of a suite (works fine for FF and IE).

异常如下所示:

编辑

拆解代码:

@AfterSuite
public void tearDown(){
  driver.quit();
}

无论有没有 RemoteDriver，都可以完美地用于 FF 和 IE.但不适用于 chrome.

Works perfectly for FF and IE with RemoteDriver and without. But not for chrome.

推荐答案

遇到了同样的问题.这里是我解决它的方法.这似乎是新版 Chrome 驱动程序的错误.使用以前版本的驱动程序 (20.0.1133.0) 为我解决了这个问题.

Faced the same problem. Here is how I resolved it. This seems to be a bug with the new version of the Chrome driver. Using the previous version of the driver (20.0.1133.0) solved this issue for me.
