Question

我有一个C＃项目，该项目实现了多个Selenium.WebDriver浏览器测试。测试通过Selenium.WebDriver.ChromeDriver中提供的ChromeDriver类针对Google Chrome。

测试在שCI环境中通过绿色测试，但是当我在本地运行它们（从Visual Studio 2019在调试模式下）时，会发生以下情况：

我看到Google Chrome在“远程控制模式”下打开。
Chrome浏览器显示空白页（URL说“ data;”。）
运行冻结在我称为ChromeDriver构造函数的行上。
60秒后，将引发以下堆栈跟踪异常：

OpenQA.Selenium.WebDriverException
  HResult=0x80131500
  Message=The HTTP request to the remote WebDriver server for URL http://localhost:27556/session timed out after 60 seconds.
  Source=WebDriver

Inner Exception 1:
WebException: The operation has timed out

我的问题是-如何确定对远程WedDriver服务器的请求为何超时？是否可以启用调试或跟踪日志？还是可以进入ChromeDriver构造函数来检查其内部工作原理？怎么样？

请注意：我不包含用于设置ChromeDriver的特定代码，因为我受到代码所有者的某些代码安全性限制。我的问题是关于调试一般情况的通用过程或工具。谢谢。
