Headless Browser Testing using HTMLUnitDriver in Selenium

[@dipikakarmakar8480]

Hi Mukesh, When i tried executing this code i am getting NoClassDefFoundError.....could you please assist me on this? using Selenium 2.53.1.

[@Mukeshotwani]

Hi Dipika, You can run chrome now in Headless mode just add --headless in chromeoptions and you can run existing chrome in headless mode. Please refer below video kzbin.info/www/bejne/kGTYZ3icj7CHfK8

[@dipikakarmakar8480]

Thanks.... using ChromeOptions it is working fine

[@anushachalana5008]

Hi Mukesh, Can we use Headless browser testing to perform some actions ?? Like sign in and clicking on some button as we do in all. I think the answer is NO. But i want to do some action on web application without showing in GUI like it can perform on backend. Please suggest how to do it

[@Mukeshotwani]

use ChromeOptions kzbin.info/www/bejne/kGTYZ3icj7CHfK8

hello mukesh and thanks for sharing video with us.i have seen your all video but i have problem with javascript element locating or please could you give demonstration of how to handle javascript in webbrowse.

Hi. Thanks for the tutorial. Clicks and submit is not working with Selenium HTMLUnitDriver. I want to do webscrpping without opening browser. How to proceed?

[@sachinjaiswal9054]

Hello Techies, Following this video we have to have the server standalone JAR else we wont be able to import the suitable file. Don't get confused that if you are having selenium JAR files that would suffice. Standalone JARs are req for this. Keep automating :) Well explained Mukesh Also i had a question, upon running i'm getting this error FAILED: HTMLUnitdriver org.openqa.selenium.WebDriverException: java.lang.IllegalArgumentException: Cann ot locate declared field class org.apache.http.impl.client.HttpClientBuilder.ssl context

Hi @Mukesh: so no solution for HtmlUnitDriver to fix this issue?

Hi mukesh, I have below code snippet for verifying title of page...its absolutely working fine and provides result as "Passed" when i use normal chrome driver...but as soon as i use headless driver like just using chromedriver along with chromeoptions then it always provides result as "Failed". I tried 4-5 times its giving the same....why is so?? please guide me...thank you public class HeadLessDriverDemo { public static void main(String[] args) throws Exception{ ChromeOptions options = new ChromeOptions(); options.addArguments("--headless"); System.setProperty("webdriver.chrome.driver","D:\\Selenium\\drivers\\chromedriver.exe"); WebDriver driver = new ChromeDriver(options); driver.get("www.facebook.com"); Thread.sleep(1000); String title = driver.getTitle(); if(title.equals("Facebook - log in or sign up")) { System.out.println("Passed"); } else { System.out.println("Failed"); } } }

Hi Mukesh, I'm trying to this from my end but the "HtmlUnitDriver();" is not recoganized by eclipse I have imported the selenium jars to my project too. WebDriver driver = new HtmlUnitDriver(); Kindly assist

[@Mukeshotwani]

Hey David in recent changes you need to add maven dependency to work with HTMLUnitDriver org.seleniumhq.selenium htmlunit-driver 2.21 In case you are using plain java project the download above jar > add into project > then try the same program.

Thank you Mukesh, for your rapid response, your solution worked.. :)

Hi Mukesh, Your tutorials are really good, simple and helpful. Keep it up. Whatever I have learnt Selenium till now is because of you. So, I would like to Thank You for this. You are awesome...:) Coming to the 1st issue I faced while going through your tutorials. I am facing an issue while using HtmlUnitDriver with selenium server standalone 2.53.1. As this version doesn't have inbuilt HtmlUnitDriver(), I added HtmlUnitDriver jar 2.52.0. to my project. Adding this recognised HtmlUnitDriver(). But when I ran the program, I got below error- java.lang.NoClassDefFoundError:com/gargoylesoftware/htmlunit/WebWindowListener. I couldn't find any way to resolve it. At last, I used selenium server standalone 2.52.0 where there is inbuilt HtmlUnitDriver(). It worked fine. Could you please try and let me know if there is any way to fix this error while using selenium server standalone 2.53.1. Note - I used the code shown in this video only.
