C# - Google chrome 在 docker Z0F4137ED1502B5045D2BAA8CZ 上运行 selenium 测试时崩溃

Question

I am getting the following error when running selenium c# tests on docker windows. Could anyone please help me on this. I am really struggling to get it solved.

The Error that I am getting is shown below:

OpenQA.Selenium.WebDriverException : unknown error: Chrome failed to start: crashed.
(chrome not reachable)
(The process started from chrome location C:\Program Files\Google\Chrome\Application\chrome.exe is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
TearDown : System.NullReferenceException : Object reference not set to an instance of an object.
at OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(Response errorResponse)
at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
at OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities desiredCapabilities)
at OpenQA.Selenium.Remote.RemoteWebDriver…ctor(ICommandExecutor commandExecutor, ICapabilities desiredCapabilities)
at OpenQA.Selenium.Chrome.ChromeDriver…ctor(ChromeDriverService service, ChromeOptions options, TimeSpan commandTimeout)
at SeleniumCore.Core.Chrome.Initialize() in C:\src\SeleniumCore\Core\Chrome.cs:line 58

The code which initializes the chrome is shown below:

public class Chrome : IBrowser
{
public RemoteWebDriver MainDriver { get; private set; }

private readonly bool Headless;

    public Chrome(AppConfigContext context)
    {
        Headless = context.Headless;
    }

    /// <summary>
    /// Initialize Chrome Browser Instance.
    /// </summary>
    public void Initialize()
    {
        ChromeOptions options = new ChromeOptions();

        if (Headless)            
            options.AddArgument("headless");
            options.AddArgument("--disable-gpu");
            options.AddArgument("--no-sandbox");
            options.AddArguments("--disable-dev-shm-usage");

        var downloadPath = Controls.DataFilePath + @"Downloads";

        Controls.CreateDirectory(downloadPath);

        options.AddUserProfilePreference("download.default_directory", downloadPath);
        options.AddUserProfilePreference("download.prompt_for_download", false);
        options.AddUserProfilePreference("disable-popup-blocking", "true");



        RemoteWebDriver driver = new ChromeDriver(@"C:\Chromedrivers\new",options);
        MainDriver = driver;

If your usecase is to connect to the RemoteWebDriver , instead of:

RemoteWebDriver driver = new ChromeDriver(@"C:\Chromedrivers\new",options);

You have to:

var MainDriver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), DesiredCapabilities.Chrome()); // replace this url with the url of your remote hub
