Thank you so much Naveen:)

[@sandeepkokane9549]

Very nice explanation.Thanks Naveen 👍

Support:
1. Say, If RWD has additional methods (which are not present in WD Interface),
then we are missing out those methods while writing WD dr= new CD();
2. Other reason to not use the above line is we need not to typecast our driver to TakesScreenShot or JSExecutor.
On Contrary:
1. Interfaces are used to achieve loose coupling and pure abstraction.
2. Additional methods in interfaces would support all the implementing subclasses.
Devs, would always prefer changes in an interface rather than disturbing multiple implemented classes, thus reducing the redundancy and errors.

[@Udzial]

Thanks @piyush , but i think first point is not right (under Support) as naveen explained from #02:40 to #02:52 , we can access the extra methods implemented by class

[@leelajain9173]

Thanks Naveen :)

[@RakeshSaineni]

Loved your explanation

Hi sir, Can we change app language through Desired Capabilities by providing some code like - Device name, packageActivity? help me plz.

[@gamyamentertainment4922]

Hey, hi '
i'm doing one project in google cloud . data pulling into google cloud with help of python script using automation.
for that we created script , inside that i was used chrome drivers , when i execute the code , the message error has been shown like ,(chrome driver executable need to be path) like that message it was shown. i was tried different web driver and remote web drivers created one docker file on that too. So, which code will work in google cloud editor. can you please give some hint ..it very helpfull to me .

[@adityanarayan3325]

I don't get my answer, why we prefer upcast to WebDriver(I) always instead of RWD class ? please put some light on it @Naveen

[@akshaygoyal1]

if i use this approach then 1 more benefit, no need to cast driver in JavascriptExecutor / TakesScreenshot
Please correct me Naveen if I am wrong

[@akshaygoyal1]

as RemoteWebdriver has all the interfaces

[@nstefi]

I don't understand. The question is why can't we write "RemoteWebDriver driver = new ChromeDriver();", but that's exactly what you write at 4:12 in the video, so it's allowed. I am trying to write the same in C# and it gives me an error: "Cannot implicitly convert type 'OpenQA.Selenium.Chrome.ChromeDriver' to 'OpenQA.Selenium.Remote.RemoteWebDriver'"

[@sailakshman3088]

For that you have to check c# selenium api, in java selenium it is fine as the architecture supports it.

[@nstefi]

​@@sailakshman3088 OK, I see that he is coding in Java, but still the question was "Can't we use ...?", so the answer is "Yes, we can", right?
In C# I used this way:
OpenQA.Selenium.IWebDriver driver = new ChromeDriver();

[@vinavmevada8419]

Great expectations. One observation is that for javascript executor and take screenshot interface is also part of hierarchy.
If we use remotewendriver we don't need to add casting for java script executor and take screenshot interface because remote web driver hold property for javascript executor and take screenshot.
But if we use Webdriver driver in this case we have to add casting for javascript executor and take screenshot because Webdriver interface does not hold property for javascript executor and take screenshot interface. 🙏

[@joshibhushan1]

We can use it because up casting is allowed in java

[@user-nl6qo8cj3i]

What will be best way to work elements inside canvas element?

[@shafiyasunkesala3384]

Hi can we write searchcontext driver = new chromedriver();?

[@naveenautomationlabs]

No you should not, you will get only FE and FEs from SearchContext.

[@shafiyasunkesala3384]

@@naveenautomationlabs thank you for quick reply. I got interview question asking can we write webdriver driver= new Remotewebdriver().
My answer was to communicate with the browser we have to create instance of chrome or Firefox etc drivers.
Pls let me know if we can add anything

[@sp38860]

​@@shafiyasunkesala3384so can we write webdriver dr = new remotewebdriver()

[@pankajborkar1072]

but what is difference why everyone using WebDriver driver = new ChromeDriver();

[@omshankergoyal1695]

Can we write RemoteWebdriver driver = new RemoteWebdriver(),

[@dhanashreeize]

technically its right but we cant write it in our script because with this line we wont be able to lauch any browser(we write remotewebdriver driver=new chromedriver or webdriver driver=new cromedriver() for launching the browsers) and secondly remotewebdriver constructor is private so we cannot create object of remotewebdriver.hence we cant write remotewebdriver driver=new remotewebdriver() as its of no use.

[@vinaymakkar3860]

why do we prefer to upcast WebDriver() instead of RWD class ? Any particular reason? Kindly explain. @naveenautomationlabs
