I faced a question in interview, he was asking like how to test a moving object in a web application.(moving images or text).
I think through descriptive programming you can tackle that object

So what needs to be tested, do u need to retrieve the moving text/image text.

I have test only the blinked text in a page and also the moving Text.(scrolling text)
