Headless Browser Test in Selenium Webdriver

 Why Headless Browser?

There are times when you don't want a browser popping each time you execute the test.

1.     Lets assume our test running in the continuous integration environment Like

• jenkins
• Banboo

Here all test will run on server.So no need any Physical things need to be done like (opening browser).We get result in Logs file at end of test.In this situation we no need to open browser .

  2.We made it to run locally also.

  3.Headless browser is very fast to excute.

In this Program:

·       Navigating to http://automationplace.blogspot.in

·       Verifying the title

Without Headless Browser

Sourcecode :

import java.util.concurrent.TimeUnit;

import org.junit.Test;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.openqa.selenium.htmlunit.HtmlUnitDriver;

import org.testng.Assert;

public class test_headlessbrowser {

      

       @Test

       public void headlessBrowser()

       {

              WebDriver driver=driver = new FirefoxDriver(); 

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

        driver.get("http://www.automationplace.blogspot.in");

       

        String title=driver.findElement(By.xpath("//*[@id='header-inner']/div[1]/h1")).getText();

        //this will verify my page title

        System.out.println(title);

        Assert.assertTrue(title.contains("Automationplace"));

       

       }

}

      

Note : The Execution is slow comparing to Headless Browser

The Execution will take 26.591 sec.

WithHeadless Browser:

To run in headless browser we need to change only one thing in the above code.

i.e)WebDriver driver=driver = new HtmlUnitDriver();

The rest of the things is same.

Source code :

import java.util.concurrent.TimeUnit;

import org.junit.Test;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import org.openqa.selenium.htmlunit.HtmlUnitDriver;

import org.testng.Assert;

public class test_headlessbrowser {

      

       @Test

       public void headlessBrowser()

       {

              WebDriver driver=driver = new HtmlUnitDriver();

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

        driver.get("http://www.automationplace.blogspot.in");

       

        String title=driver.findElement(By.xpath("//*[@id='header-inner']/div[1]/h1")).getText();

        //this will verify my page title

        System.out.println(title);

        Assert.assertTrue(title.contains("Automationplace"));

       

       }

}

  

If you Run the above code

The Execution will take only 7.738 sec
