Headless Browser Testing Using PhantomJSDriver in Selenium WebDriver

Headless Browser Testing Using PhantomJSDriver In Selenium WebDriver

In the earlier post, we have seen some brief explanation on what is headless browser and in this post, we learn how to perform headless browser testing using PhantomJSDriver in Selenium WebDriver. PhantomJSDriver is one of the drivers of Selenium WebDriver. HtmlUnitDriver and PhantomJSDriver are most popular headless browsers.

PhantomJS is used for Headless Browser Testing of Web Applications that comes with in-built GhostDriver. This means that the rendered web pages are never actually displayed.

Advantages:

Lightweight
Proxy server support
Fastest implementation of WebDriver
Platform Independent
Allows us to simulate different browsers having different versions.

You could download PhantomJSDriver executable file from here – PhantomJS Driver

Download PhantomJSDriver jar file from here – PhantomJS Jars

Usually, to run Selenium Scripts using Firefox, we initialize the Firefox driver.

WebDriver driver = new FirefoxDriver();

1	WebDriver driver = new FirefoxDriver();

Whereas while running Selenium Scripts using PhantomJSDriver you need to write the below statement

WebDriver driver = new PhantomJSDriver ();

1	WebDriver driver = new PhantomJSDriver ();

Remaining statements in your script will be as usual.

Let’s see a working example using PhantomJSDriver in Selenium WebDriver:

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.testng.annotations.Test;

public class HeadlessBrowser {
	
	@Test
	public void phantomJSDriver() throws Exception{
		//Set the path of the phantomjs.exe file in the properties
		System.setProperty("phantomjs.binary.path", "D:\\Selenium\\Drivers\\phantomjs.exe");
		// To declare and initialize PhantomJSDriver
		WebDriver driver = new PhantomJSDriver();
		// Download link is http://phantomjs.org/download.html
		// Set implicit wait 
		driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
		// Open "Google.com and search SoftwareTestingMaterial.com"
		driver.get("https://www.google.com");
		// To locate the searchbox using its name
		WebElement element = driver.findElement(By.name("q"));
		// To enter text "softwaretestingmaterial.com"
		element.sendKeys("softwaretestingmaterial.com");
		// To submit
		element.submit();
		//Click on Software Testing Material link
		driver.findElement(By.linkText("Software Testing Material")).click();
		// Get the title of the site and store it in the variable Title
		String Title = driver.getTitle();
		// Print the title
		System.out.println("I am at " +Title);
	}
}

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.phantomjs.PhantomJSDriver;

import org.testng.annotations.Test;

public class HeadlessBrowser {

@Test

public void phantomJSDriver() throws Exception{

//Set the path of the phantomjs.exe file in the properties

System.setProperty("phantomjs.binary.path", "D:\\Selenium\\Drivers\\phantomjs.exe");

// To declare and initialize PhantomJSDriver

WebDriver driver = new PhantomJSDriver();

// Download link is http://phantomjs.org/download.html

// Set implicit wait

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

// Open "Google.com and search SoftwareTestingMaterial.com"

driver.get("https://www.google.com");

// To locate the searchbox using its name

WebElement element = driver.findElement(By.name("q"));

// To enter text "softwaretestingmaterial.com"

element.sendKeys("softwaretestingmaterial.com");

// To submit

element.submit();

//Click on Software Testing Material link

driver.findElement(By.linkText("Software Testing Material")).click();

// Get the title of the site and store it in the variable Title

String Title = driver.getTitle();

// Print the title

System.out.println("I am at " +Title);

}

Output:

Different Browser Versions using PhanthomJSDriver:

We could test our scripts on different browser versions using PhanthomJSDriver. Yes, it allows us to choose our preferred browser version. See the below screenshot.

WebDriver driver = new PhanthomJSDriver(BrowserVersion.FIREFOX_3);

1	WebDriver driver = new PhanthomJSDriver(BrowserVersion.FIREFOX_3);

I am concluding this post about headless browser testing using PhanthomJSDriver. Check out our other post on how to perform headless browser testing using HtmlUnitDriver in Selenium WebDriver.

What is the difference between HTML unit driver and phantomjsdriver

  Hi Prajwal, Both HtmlUnitDriver and PhanthomJSDrivr are headless browsers. HtmlUnit Driver uses Rhino JavaScript engine and PhanthomJS uses Webkit javascript engine. We could use any of these two for headless browser testing. There are some other headless browsers but these two are popular ones. HtmlUnitDriver is much faster than PhanthomJSDriver.
