Great explanation of all important topics related to instantiation of WebDriver and typecasting I could find in one video, thank you!

[@HYRTutorials]

Thanks buddy 😊

[@gpavankumar175]

Superb explaination. I was wondering why we are typecasting and what is it. Thanks, now clear.

[@HYRTutorials]

Super 😊

[@anichavan11]

Very good explanation and after watching full video came to know the main reason for typecasting. Please make more videos like this. 👍

[@parvinkouliev11]

Excellent explanation. Can you also explain why don't we just use RemoteWebDriver class to create driver instance in this case which would not need typecasting since RemoteWebDriver inherits all methods of all 3 interfaces.

[@HYRTutorials]

Yes we can use remotewebbriver class as well. There is nothing wrong in using it but the only reason we usually use the webdriver is because of its name. Remotewebbriver is more often used for remote execution where you mention the ip address and port number. So for all local executions we use webdriver. It's just a standard we usually follow but if we want to maintain the uniformity then we can always use the remotewebbriver class.

[@youshouldknow9369]

Till Selenium v3, ChromeDriver extends RemoteDriver. This ChromeDriver was a WebDriver implementation that controlled the google-chrome browser running on the local machine.

[@manikandankm3974]

@@HYRTutorials Hello Sir , I have a doubt here , Even we use Webdriver instance here , Remotewebdriver Inherits its properties and Again All the browser class INHERITS the properties of Remowebdriver ( Chromedriver Extends RemoteWebdriver) , In this case we don't requires typecasting right , The browser classes have all the method implementation of JS Interface and driver automatically takes the Methods of JS ?? Please clarify.

[@ksdnsdkumar1375]

You didn't mention "RemoteWebDriver" anywhere, then why did you include in the diagram?

[@HYRTutorials]

Remotewebdriver is the class where all the interferences are implemented buddy

[@RAHULKUMAR-rb6pl]

Sir whenever we said typecasting for javascriptExecutor in that situation to be more precise we can say it is also upcasting or not

[@yaswanthtirupathi6551]

Thank you so much bro

[@HYRTutorials]

Happy learning buddy

[@madhukrishna5704]

As per the typecasting rule: The object(TakesScreenshot) type should be same or parent of runtime object of driver,i.e(Cromedriver). 1)It works when both are related to class. 2)But i don't know when they are interfaces and classes.(TakesScreenshot is a interface and Chromedriver is a class). Is same typecasting rule applied to above statements? If not could pls clarify my doubt?

[@sujitblues]

please create java interview series (coding & conceptual ) both

[@mjj3tube]

When we say Takescreenshot ts = (Takescreenshot ) driver , is this up casting or down casting ?

[@HYRTutorials]

you could say upcasting only but we shouldn't use the down casting or upcasting words here instead we should simply call it as typecasting.

[@mjj3tube]

@@HYRTutorials got it thanks for the kind response

[@ManiKandan-vo2qr]

Hello Sir , JavaScript Executor is also an interface right? So Even though we type cast into JavaScript executor , How can we access the method executescript() which is un-Implemented still in interface ? Please tell me

[@HYRTutorials]

Basically here we alrdy have the fully implemented driver but when u r creating the driver instance type as webdriver then you can only access methods inside the webdriver interface even though it has the JavaScriptExecutor methods code. So that is why we are typecasting it to JavaScriptExecutor.

[@Drake9w1]

@@HYRTutorials Hello Sir. I had the same question and I did not understand this answer. Could you please simplify.

[@HYRTutorials]

@@Drake9w1 to understand this, have some basic understanding of interfaces and classes. It's very easy once you got some basic idea about those.

[@swapnabhaskaruni]

@@HYRTutorials so do you mean because we write a statement WebDriver driver = new ChromeDriver() and the ChromeDriver class has all the methods implemented from WebDriver, JavaScriptExecutor and TakesScreenshot we are able to typecast the driver and access other interface class methods. But if we write WebDriver driver = new WebDriver() then the typecast would not work. Please correct me.

[@HYRTutorials]

@@swapnabhaskaruni first of all you can't create an object for webdriver. Check your second statement one more time

[@swapnabhaskaruni]

Looks like there are more selenium tutorials in english playlist than the selenium telugu playlist. If there are any missed topics in telugu playlist can you do them in telugu too. Its just easy to process in telugu. and i feel because our mother tongue is telugu explanation and understanding is easier and faster in telugu. Please consider my request.

[@HYRTutorials]

Some of the additional topics are covered in English and the interview questions are also created in English only. I will create them in telugu language but it may take some time

[@harisake6068]

Thank you

[@MyGreatAchievers]

when there is no relashion between webdriver and takescreenshort references then how can we typecasting it? please explain.

[@kumarshubham5537]

Can you please tell me how to say these answers precisely in interview as we won't have any script over there.

[@subhashinic7000]

Why are we not typecasting it when we use ChromeDriver driver; ?

[@HYRTutorials]

Because typecasting is not required buddy

[@adityatripathi3379]

Why we don't write RemoteWebDriver driver = new ChromeDriver(); ?

[@HYRTutorials]

We can write and there is nothing wrong in that. It's just that by name we can see. Remotewebdriver is mostly used for remote connections.

[@rishabhmehta9498]

[@HYRTutorials]

Happy learning buddy 😊

[@babupemmada1580]

What is unimplemented methods sir?

[@HYRTutorials]

In java we have the concept of abstract methods and non abstract methods. Abstract methods are also called as unimplemented methods. These methods are present in either interface it abstract class.

[@abinashprakash804]

awesome

[@HYRTutorials]

Thankyou buddy 😊

[@mycreativelife2837]

[@HYRTutorials]

Thanks buddy 😊

[@raghavendrasaicharan3188]

What is difference between extends and implements.

[@HYRTutorials]

Implements and extends are keywords. Implements is used when you want implement the unimplemented methods from interfaces. Extends is used when you want to inherit other class properties like attributes and methods. So it is mostly used in inheritance concepts.

[@ferozkhanr6653]

Can we declare like RemoteWebDriver driver = new chromeDriver();

[@HYRTutorials]

Yes we can declare buddy. When working with remote execution that's how we do it

[@ferozkhanr6653]

@@HYRTutorials How to handle captcha in selenium, any third party lib is supported ?

[@HYRTutorials]

@@ferozkhanr6653 No we cant handle the capta in selenium buddy. If your application has that feature then you can ask the dev to provide some property for the capta control or you can ask them to turnoff that in the test enevs

[@Sowmya598]

Sir.. every one uses if else condition to choose d browser.. but u have used switch is der any reason behind dat.. thanks in advance

[@HYRTutorials]

In if else condition everytime u r checking minimum 1 condition and if that condition fails then again it will go for another condition. Like that it continues condition checking. So to avoid that we have to use switch condition.

[@Sowmya598]

Thanks for d reply..😊 so in case of switch condition it directly jumps to d case on which we want to run our testscripts without​ checking each n every case

[@HYRTutorials]

Exactly.
