Unable to launch HtmlUnitdriver through Selenium 3.4.0

Question

I am tried to run the HtmlUnitDriver with selenium 3.4 and chrome Version 64.0.3282.119 (Official Build) (32-bit). My code is:

package eclipse;

import java.io.File;

import org.openqa.selenium.By;
import org.openqa.selenium.Capabilities;
import org.openqa.selenium.UnexpectedAlertBehaviour;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;  
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.testng.Assert;
import org.testng.annotations.Test;

import com.gargoylesoftware.htmlunit.BrowserVersion;

public class Unit
{
    WebDriver driver;
    public static void main(String[] args){
        WebDriver driver;
        driver = new HtmlUnitDriver(BrowserVersion.CHROME);
        driver.get("http://www.google.com");
        System.out.println(driver.getTitle());

    }
    }

Answer 1

Use this code to Initialize headless browser :

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.CHROME ,true);
driver.get("your web URL");

Answer 2

To invoke HtmlUnitDriver with Selenium v3.4.0 you don't need ChromeDriver or Chrome Browser Client instead you can use the org.openqa.selenium.htmlunit.HtmlUnitDriver module following the solution below :

• Code Block :

  package HtmlUnitDriver;
  
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.htmlunit.HtmlUnitDriver;
  
  public class htmlUnitDriver {
  
      public static void main(String[] args) {
  
  
          WebDriver driver = new HtmlUnitDriver();
          driver.manage().window().maximize();
          driver.get("https://www.facebook.com/");
          System.out.println("Invoking Facebook through HtmlUnitDriver");
          System.out.println(driver.getTitle());
      }
  }
  

• Console Output :

  Invoking Facebook through HtmlUnitDriver
  Facebook – log in or sign up
  

Note : Ensure that HtmlUnitDriver() is not resolved from :

com.gargoylesoftware.htmlunit.BrowserVersion;

I am tried with this : But output is - log4j:WARN No appenders could be found for logger (com.gargoylesoftware.htmlunit.WebClient). log4j:WARN Please initialize the log4j system properly. Invoking Facebook through HtmlUnitDriver – Shawana

can you please tell me the HtmlUnitDriver compatible version ? – Shawana

@Shawana This code block will work on Selenium v3.4.0 and the recent Selenium v3.12.0. Simply copy-paste the code and change the Package Name – Talmud

I am using v3.4.0... i have tried simply copy and paste the code but page title are not coming for me ? – Shawana

@Shawana These warning messages log4j:WARN No appenders could be found for logger (com.gargoylesoftware.htmlunit.WebClient). log4j:WARN Please initialize the log4j system properly. are coming as you haven't configured Log4j module for this project. Else you are getting proper Console Output as follows Invoking Facebook through HtmlUnitDriver I think your program is executing just perfect :) – Talmud

Version for Log4j ? – Shawana

@Shawana Leave out Log4j for now. That is a separate module to generate more verbose Log Messages. Your program is working fine. – Talmud

If reinstalled the log4j its enough ? otherwise how I will get output ? – Shawana

@Shawana Cool down man, take a deep breathe, your program is working fine. You are getting expected output in the console as Invoking Facebook through HtmlUnitDriver – Talmud

The other log messages are WARN messages and you can ignore them for the time being. – Talmud
