What is an Exception?
An exception is an event that interrupts the execution of the program without giving the output. In simple words, any issue which stops your script in between the execution is an exception. When an exception occurs in the program then It halts the normal flow of the program and creates an object. The exception object contains a lot of debugging information such as method name, line number where the exception occurred and type of exception.
Common Type of Exceptions:
When a code is not initializing the web driver or when the web driver performs actions right after closing the browser.
When an element does not identify on the web page during the run time process.
When a user tries to interact with an element that is hidden on the page. For Example, when a user tries to perform click action on the sub-heading in the drop-down list.
When an element is present but disable and not clickable on the web page.

Stale means no longer. This exception occurs when a reference variable is no longer on the DOM page. This happens due to the following reasons:
