无法使用 selenium webdriver 远程运行 CHROME

Question

我正在使用 python 和 selenium webdriver 在网格上运行和自动化测试用例。我可以在集线器和节点上使用一些警告消息启动 FIREFOX 浏览器，但它工作正常。但问题是使用 CHROME 启动同一个 Web 应用程序。我尝试了所有可能的方法，但没有任何帮助。 每当我必须在本地使用 CHROME 浏览器时，我都会运行 chromedriver.exe 来启动应用程序。但我不知道如何远程解析chromedriver.exe 以在那里启动同一个应用程序。我什至尝试在节点上安装并开始运行 chromedriver 并检查它是否开始运行，但没有任何帮助。并且还设置了系统属性...

java -jar ./selenium-server-standalone-2.35.0.jar - Dwebdriver.chrome.driver='/opt/drivers/chromedriver' -role webdriver -hub  http://192.168.1.10:4444/grid/register -port 5566 -browser browserName=chrome

输出：

问题似乎是您试图打开指向错误位置的文件：

WebDriverException: Message: The driver executable does not exist:
  C:\Users\user\'C:\Users\user\Desktop\chromedriver.exe' Stacktrace:

顺便说一句，如果你使用 python，你为什么要尝试用 java 启动 chromedriver ..

如果您使用的是 python，您可以检查以下内容： test suite python - webdriver
