- Object executeScript(String arg0, Object… arg1);
- Object executeAsyncScript(String arg0, Object… arg1);
Let’s learn more basics:
You must need to know the hierarchy of classes of interfaces in Selenium webdriver.
If you create a browser driver class object and up cast it to WebDriver as below:
WebDriver driver= new ChromeDriver();
You will see “Hello” printed in browser console.
If you create a browser driver class object and do not up cast it as below:
ChromeDriver driver= new ChromeDriver();
Output will be same as Case 1 above.
If you create a browser driver class object and up cast to RemoteWebDriver it as below:
RemoteWebDriver driver= new ChromeDriver();
Hope you must be clear now when up casting is needed.

I started from basics and went through so many selenium tutorials. Thanks to Mukesh Otwani as his tutorials are easy and cover basics to advance. I have habit of exploring concepts by deep diving. I used to make notes. I thought of sharing my knowledge through posts and now I am here. #KeepLearning #ShareLearning
