Two Great Web Drivers to Use With Selenium

Headless Browser in HtmlUnit Driver

HtmlUnit Driver is getting famous because of its lightweight and fast features. It is also known as a headless browser driver. It does not provide any GUI while executing programs.

Some Examples of Headless Drivers Are:

  • HtmlUnit
  • PhantomJS
  • ZombieJS
  • Watir-webdriver
  • Ghost

Advantages of HtmlUnit Driver

  • Lack of GUI, which is why it takes less time and memory to run.
  • Works fast compared to Google Chrome, Firefox or Safari.
  • It supports Java and JavaScript.
  • Easy to use and understand

Disadvantages of HtmlUnit Driver

  • Difficult to perform user interface testing.
  • Exhaustive testing is impossible using this driver.

Code Snippet

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class Test {

public static void main(String[] args) throws InterruptedException 
{
WebDriver driver = new HtmlUnitDriver();
driver.get("http://softwaretestingbooks.com/");
System.out.println(driver.getTitle());
driver.quit();
}
}

Using Gecko Driver in Selenium 3.0

If you are using Firefox 47 or above, then Gecko Driver is required to run scripts in Selenium Webdriver.

If you are using Selenium version 2 or below, you don’t need Gecko Driver. You can download selenium-server-standalone-2.53.1.jar from here.

Without Gecko Driver:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Test 
{
public static void main(String[] args) 
{
WebDriver driver = new FirefoxDriver();

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

driver.quit();
}
}

Output :

Throws an exception “java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property;”

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver.

Using Gecko Driver in Selenium 3.0:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Test {

public static void main(String[] args) throws InterruptedException 
{
System.setProperty("webdriver.gecko.driver", "E:\selenium\geckodriver.exe"); //("webdriver.gecko.driver","Write path of Gecko Driver exe")
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
System.out.println("Code Run Successfully");
Thread.sleep(2000);
driver.quit();
}

}
