Headless Browser Testing using HTMLUnitDriver in Selenium - Session 10

Headless Browser Testing using HTMLUnitDriver in Selenium:

Advantages of HtmlUnitDriver:

+Test execution using HtmlUnitDriver is very fast. Since it is the fastest implementation of Selenium WebDriver.
+Being headless and fast, it is an ideal choice for web scrapping.
+Its browser - htmlUnit is Java based. Hence, it is platform independent.
+It also supports JavaScript execution through in-built Rhino javascript engine.

========================================================

Limitations of HtmlUnitDriver:

-Being non-GUI makes it difficult to create scripts and debug issues while scripting.
-The Rhino javascript engine of HtmlUnitDriver makes it unsuitable to emulate other popular browser's javascript behaviour.

Does it mean no timeout methods are required while performing headless browser testing?

[davidvilla]

hI nAVEEN, tHANKS FOR THE CLASS. u SAID IT IS NOT AVAILABLE IN SELENIUM 3X, DOES IT MEAN IT IS NOT USING ANYMORE?

[manideepmukka]

hi, can we perform the click button options using the headless browser... ex: browser should open the fb and login and enter the text in "post" box and click on post and then logout.

will it work in headless browser?

[ashwinib]

Hi Naveen ...one query in this video, you have already used implicit wait of 20 seconds why are we again using thread .sleep here

[MyWalia]

Hi Naveen, Is it required to give dynamic wait with HTMLunit driver...or thread.sleep ?

[MyWalia]

So that means for HTMLunitdriver, we do not need to do setProperty because its a jar file and not an exe file like chromedriver or geckodriver?

[suryakumaris]

Hi Naveen, if i execute WebDriver driver= new HtmlUnitDriver(); means getting exception like Type mismatch: cannot convert from HtmlUnitDriver to WebDriver. I installed HtmlUnitDriver in my proj. if i give like WebDriver driver = new means its executing properly. whats the problem in this?

[madhurinemade]
