Selenium : handle Pop Up/Banner/Alert box which is displayed as we open any WebPage and gets close by pressing Escape button

We might have noticed that - when a page is opened a pop up banner gets displayed and when press "escape" button on keyboard, then this pop up/Alert box OR Banner gets closed.

How to achieve this through Selenium

Ans: we have to use css selector to locate the body text of HTML and then we need to press ESCAPE button

Note: CSS selector is alone selector which can access entire body of HTML

Sample Code:

driver.findElement(by.xpath(" ")).sendKeys(Keys.ESCAPE);
