How to start ChromeDriver in headless mode

问题

I want to try out headless chrome, but I am running into this issue, that I can't start the driver in headless mode. I was following google documentation. am I missing something ? The code execution gets stuck in var browser = new ChromeDriver(); line

Here is my code:

var chromeOptions = new ChromeOptions
{
    BinaryLocation = @"C:\Users\2-as Aukstas\Documents\Visual Studio 2017\Projects\ChromeTest\ChromeTest\bin\Debug\chromedriver.exe",
    DebuggerAddress = "localhost:9222"
};

chromeOptions.AddArguments(new List<string>() {"headless", "disable-gpu" });

var browser = new ChromeDriver(chromeOptions);


browser.Navigate().GoToUrl("https://stackoverflow.com/");
Console.WriteLine(browser.FindElement(By.CssSelector("#h-top-questions")).Text);

UPDATE
Chrome version 60 is out so all you need to do is to download Chromdriver and Selenium via Nuget and use this simple code and everything works like a charm. Amazing.

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

...



var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("headless");

using (var browser = new ChromeDriver(chromeOptions))
{
  // add your code here
}

There is a solution until the official release of Chrome 60 will be released. You can download Chrome Canary and use headless with it. After installation set BinaryLocation to point to chrome canary also comment out the DebuggerAddress line(it forces chrome to timeout):

var chromeOptions = new ChromeOptions
{
    BinaryLocation = @"C:\Users\2-as Aukstas\AppData\Local\Google\Chrome SxS\Application\chrome.exe",
    //DebuggerAddress = "127.0.0.1:9222"
};

chromeOptions.AddArguments(new List<string>() { "no-sandbox", "headless", "disable-gpu" });

var _driver = new ChromeDriver(chromeOptions);

For you that did not get reference for ChromeDriver. Use this step :

Download the dll from this: http://seleniumtestings.com/selenium-download/
Extract, and you should see: Selenium.WebDriverBackedSelenium.dll, ThoughtWorks.Selenium.Core.dll, WebDriver.dll and WebDriver.Support.dll
Add those files via "Add Reference"

Now you can use it:

String url = "http://www.google.com";
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments(new List<string>() {
    "--silent-launch",
    "--no-startup-window",
    "no-sandbox",
    "headless",});

var chromeDriverService = ChromeDriverService.CreateDefaultService();
chromeDriverService.HideCommandPromptWindow = true;    // This is to hidden the console.
ChromeDriver driver = new ChromeDriver(chromeDriverService, chromeOptions);
driver.Navigate().GoToUrl(url);

====

If after you run, you are still facing error about no ChromeDriver.exe file, try to add the Selenium.WebDriver.ChromeDriver, WebDriver.ChromeDriver, WebDriver.ChromeDriver.win32, Selenium.Chrome.WebDriver via nuget.

As alternative:

Add 2 libraries via NuGet like below picture.

Try below Code:

String url = "http://www.google.com";
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments(new List<string>() { "headless" });

var chromeDriverService = ChromeDriverService.CreateDefaultService();
ChromeDriver driver = new ChromeDriver(chromeDriverService, chromeOptions);
driver.Navigate().GoToUrl(url);

回答4:

What OS you're running? I see on developers.google.com/web/updates/2017/04/headless-chrome that headless won't be available on Windows until Chrome 60.

回答5:

Below i have given how to set the headless to true for firefox and chrome browsers.

FirefoxOptions ffopt = new FirefoxOptions();
FirefoxOptions option = ffopt.setHeadless(true);
WebDriver driver = new FirefoxDriver(option);


ChromeOptions coptions = new ChromeOptions();
ChromeOptions options = coptions.setHeadless(true);
WebDriver driver = new ChromeDriver(options);
