How to connect to Chromium Headless using Selenium

I would like to use chromium headless for automated testing using selenium. (https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md)

I do have the headless version already running on 9222. So if i open http://10.252.100.33:9222/json/I do get 

[ {
   "description": "",
   "devtoolsFrontendUrl": "/devtools/inspector.html?ws=127.0.0.1:9223/devtools/page/0261be06-1271-485b-bdff-48e443de7a91",
   "id": "0261be06-1271-485b-bdff-48e443de7a91",
   "title": "The Chromium Projects",
   "type": "page",
   "url": "https://www.chromium.org/",
   "webSocketDebuggerUrl": "ws://127.0.0.1:9223/devtools/page/0261be06-1271-485b-bdff-48e443de7a91"
} ]

As a next step I'd like to connect selenium to the headless chromium. But when i try

final DesiredCapabilities caps = DesiredCapabilities.chrome();
final WebDriver driver = new RemoteWebDriver(new URL("http://localhost:9222/json"), caps);
driver.get("http://www.google.com");

I do get the following logout

Jän 24, 2017 7:14:45 PM org.openqa.selenium.remote.ProtocolHandshake createSession

for me works above solution:

chromeOptions.setBinary("/usr/bin/chromium-browser");

but i had to add (becouse of devtools):

chromeOptions.addArguments("--remote-debugging-port=9222");

and disable firewall

Use the following code:

ChromeOptions options = new ChromeOptions();  
options.setHeadless(true); //Set Chrome option
driver = new ChromeDriver(options);

and you will get "Headless" Chrome!

Full code

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;  //import ChromeOptions

public class web_crawl {
     
    private static WebDriver driver = null;
 
    public static void main(String[] args) {
 
      
       ChromeOptions options = new ChromeOptions();
       options.setHeadless(true);
       
       driver = new ChromeDriver(options);   
       driver.get("http://www.google.com");   //The website you want to connect to 
     
 
    }

System.setProperty("webdriver.chrome.driver", "Path of the chrome driver");
ChromeOptions chromeOptions = new ChromeOptions();  
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("--window-size=1920,1200");
webDriver = new ChromeDriver(chromeOptions);

The invisible browser window is only 800x600 in size. Therefore, you need to set the desired screen size with an additional argument

I think the readme is a little bit misleading. You don't have to start Chromium itself and you can use the RemoteWebDriver. Make sure that a chromedriver is installed (https://sites.google.com/a/chromium.org/chromedriver/home).

  • Start chromedriver (e.g. ./chromedriver or ./chromedriver --port=9515)
  • Then you have tell the chromedriver to use Chromium instead of Chrome
  • Add --headless as an additional argument

Code should look like this:

final ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setBinary("/usr/bin/chromium-browser");
chromeOptions.addArguments("--headless");
desiredCapabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
WebDriver driver = new RemoteWebDriver(url, desiredCapabilities);

Worked for me on Ubuntu Linux.

if you are using selenium 3+ chrome driver , you can simply use chrome options and initiate driver. Check details in a project

Example Project on Chrome Headless running with different options

 options.setHeadless(true)

Alternatively if your running it locally you can just do it like this. In scala.

val chromeOptions = new ChromeOptions
chromeOptions.addArguments("--headless")
new ChromeDriver(chromeOptions)

Chrome 59 has the ability to create instance as headless . I have tried for Windows with new chrome driver 2.30 and it worked for me https://www.automation99.com/2017/07/how-to-use-chrome-headless-using.html?m=1
