Can Selenium handle a window-based pop-up?

Yes, Selenium WebDriver can handle window-based pop-ups. On clicking a link or a button, another window may open with information or an advertisement. The getWindowHandles and getWindowHandle methods are used to manage windows. The getWindowHandles method stores all the IDs of opened windows as a Set data structure.

The getWindowHandles method holds all the opened window handle ids, so we can use the iterator and next methods to iterate through them.
