Selenium: Run test in headless mode

Many a times we feel the need to run our UI automation tests in headless mode ( No browser visible) .
Few advantages are:

1. Faster execution, as it does not use system resource(memory and gpu) to launch browser .
2. When we do not need to bother about browser view and do not want any distraction while running tests. (Working in local machine)

Code:

ChromeOptions options= new ChromeOptions();
//Based on your screen resolution
options.addArguments(“window-size=1400,800”); 
options.addArguments("--headless");
options.addArguments("--disable-gpu");
WebDriver driver =  new ChromeDriver(options);
driver.get("https://testapplicationurl.com");

You can also take screenshots in headless mode.
