How To Run Selenium Tests In Headless Google Chrome

We are going to use ChromeOptions class to run out test case on Chrome Browser in HeadLess mode.
ChromeOptions is a Class to manage options specific to ChromeDriver.

Please refer below Program to run tests in headless mode using Chrome Driver.

import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.testng.annotations.Test;

public class HeadlessChrome {
 @Test
 public void headlessTest() throws IOException {
  System.setProperty("webdriver.chrome.driver",
    "C:\\Users\\Hitendra\\Downloads\\chromedriver_win32 (1)\\chromedriver.exe");
  ChromeOptions chromeOptions= new ChromeOptions();
  chromeOptions.addArguments("headless");
  chromeOptions.addArguments("window-size=1200x600");
  WebDriver driver= new ChromeDriver(chromeOptions);
  driver.get("https://www.google.com/");
  System.out.println("Test Start");
  System.out.println("Google title is: "+driver.getTitle());
  System.out.println("Test End");
  TakesScreenshot takesScreenshot = (TakesScreenshot) driver;
  File source = takesScreenshot.getScreenshotAs(OutputType.FILE);
  FileUtils.copyFile(source, new File("D:\\Workspace_Eclipse\\WebDriverConcept3\\ScreenShot\\Headless.png"));
  driver.close(); 
 }
}
