How To Run Selenium Test In Headless Mode in Chrome Browser

16 Aug

Headless Testing is very useful in Test Automation and Selenium Webdriver also supports now Headless Testing. Previously we have used HTMLUnitDriver and PhantomJS driver Run Selenium Test In Headless Mode.

In case you are not familiar with Headless Mode then in just line I can say that “Test will run without GUI” it means test will be running in background and you will get the result after execution.

Now Current Chrome Browser and Firefox Browser also supports Headless mode.In order to run your test in Headless mode make sure you use latest Chrome browser and latest Chrome Driver as well..

Program 1- Run Selenium Test In Headless Mode

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.testng.annotations.Test;

public class ChromeHeadlessBrowser {

@Test
public void myfirst()
{
// Set the chrome driver
System.setProperty(“webdriver.chrome.driver”,”./chromedriver.exe”);

// Create Object of ChromeOption Class
ChromeOptions option=new ChromeOptions();

//Set the setHeadless is equal to true which will run test in Headless mode
option.setHeadless(true);

// pass the option object in ChromeDriver constructor
WebDriver driver=new ChromeDriver(option);

// Provide any url
driver.get(“https://vistasadprojects.com/mukeshotwani-blogs-v2/”);

System.out.println(“Title is “+driver.getTitle());

// Close the instance
driver.quit();

}

}

we also have another approach where we can set argument and then pass the options class object to ChromeDriver constructor. I found  a very interesting blog where author has mentioned many arguments which we can pass in ChromeOption and many of them are useful for our Selenium Test as well.

Recently I also published one YouTube video which talks about ChromeOption in Selenium and Different Usage of the same.

Another approach to  Run Selenium Test In Headless Mode

// Create Object of ChromeOption Class
ChromeOptions option=new ChromeOptions();

//add the –headless argument in option class which will run test in Headless mode
option.addArguments(“–headless”);

// pass the option object in ChromeDriver constructor
WebDriver driver=new ChromeDriver(option);

Selenium Test in Headless Mode for Firefox ?

Note- Same thing will be application for Firefox as well so need to make much Changes in Code in First Program just change ChromeDriver to FirefoxDriver and rest process will remain same. FirefoxDriver required Gecko Driver now so make sure you use Latest Gecko driver to work Firefox in Headless mode.

I also have detailed article and video where we discussed how to use Gecko driver in Selenium

Before we end let’s talk about screenshot as well, you must be thinking if test is running in headless mode then how it will capture screenshot right? Selenium already handled this so no need to change the code for screenshot. You can use old way to capture screenshot and it will work in same way.

I have detailed article and video where we discussed how to capture screenshot and capture screenshot only when test fails.
