How to set up Selenium and ChromeDriver to run in headless mode

问题

I am trying to run a browser test using xUnit, Selenium, and Chrome Canary (headless mode) but I keep getting this error:

OpenQA.Selenium.WebDriverException
The HTTP request to the remote WebDriver server for URL 
http://localhost:58692/session timed out after 60 seconds.

Here's my code:

var chromeOptions = new ChromeOptions
    {
        BinaryLocation = @"C:\Users\<USERNAME>\AppData\Local\Google\Chrome SxS\Application\chrome.exe",
        DebuggerAddress = "127.0.0.1:9222"
    };

chromeOptions.AddArguments("no-sandbox", "headless", "disable-gpu");
_driver = new ChromeDriver(chromeOptions) {Url = Url};

I'm quite new to C# so I'm not sure if I'm doing something blatantly wrong, or if I'm just missing a setting. Googling the above error told me that I need to set the debugger address and use the no-sandbox flag, but neither seem to be helping.

Using these versions:

selenium 3.4
chromedriver 2.29
xunit 2.2

回答1:

Taking out the debugger address made it work.

var chromeOptions = new ChromeOptions
{
    BinaryLocation = @"C:\Users\<USERNAME>\AppData\Local\Google\Chrome SxS\Application\chrome.exe",
};

In case that others will get here while googling...

What worked for me was to download the latest chrome-driver from this link: https://sites.google.com/a/chromium.org/chromedriver/downloads

Happy coding :)
