What is headless browser ?

Browser which is not visible to user is known as headless browser.
They are also know as Ghost browser.
in terms of selenium, Browser which will be controlled by selenium but will not be visible to user is known as headless browser testing.


Different kind of headless browser

In selenium we have following headless browser :

1).HtmlUnit
2).PhantomJS
3).Ghost
4).ZombieJS
5).Watir-webdriver
6).Jbrowser


Lets Talk about HtmlUnitDriver
1). The fastest browser among all the browsers
2). Excellent JavaScript support
3).Support for the HTTPS and HTTP protocols
4).Support for HTML responses
5).Support for cookies
5). Proxy server support
7). Support for basic and NTLM authentication
8).Support for submit methods GET and POST
9). Ability to customize the request headers being sent to the server
10). Ability to determine whether failing responses from the server should throw exceptions or should be returned as pages of the appropriate type


Cons of HtmlUnitDriver
1).It cannot emulate other browsers JavaScript behavior
2).Many times it get for complicated scripts

How to configure HtmlUnitDriver in Selenium Project

First of all download the jar files of HTMLUnitDriver by using below links :=

Download from website : Click here
download from google driver : Click here

Now create the Java Project & add this Jar file in your project 

 


Code

import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import java.io.File;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
public class GhostDR
{
WebDriver driver;
@BeforeTest
public void g()
{
driver = new HtmlUnitDriver();
//System.setProperty("webdriver.chrome.driver", "D:\\Selenium\\Complete selenium\\chromedriver.exe");
//driver = new ChromeDriver();
driver.navigate().to("http://www.way2testing.com");
}
@Test
public void h()
{
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
System.out.println(driver.getTitle());
}
}

System.setProperty("phantomjs.binary.path", file.getAbsolutePath())

3).WebDriver driver = new PhantomJSDriver();



Code

import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import java.io.File;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import org.openqa.selenium.phantomjs.PhantomJSDriver;
public class PISOFT
{
WebDriver driver;
@BeforeTest
public void g()
{
File file = new File("D:\\Selenium\\Complete selenium\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
System.setProperty("phantomjs.binary.path", file.getAbsolutePath());
driver = new PhantomJSDriver();
//driver = new HtmlUnitDriver();
//System.setProperty("webdriver.chrome.driver", "D:\\Selenium\\Complete selenium\\chromedriver.exe");
//driver = new ChromeDriver();
driver.navigate().to("http://www.way2testing.com");
}
@Test
public void h()
