Question

How can we handle web-based pop-up?

Answer

WebDriver offers the users a very efficient way to handle these pop-ups using Alert interface. There are the four methods that we would be using along with the Alert interface.

void dismiss() - The dismiss() method clicks on the “Cancel” button as soon as the pop-up window appears.

   void accept() - The     accept() method clicks on the "Ok" button as soon as the pop-up window     appears.

 String getText() - The getText() method returns the text displayed on the     alert box.

void sendKeys(String stringToSend) - The sendKeys() method enters the specified string pattern into the alert box.
