How to determine whether a new Canon 7D have autofocus problem…

I just got my new 7d few days ago…seeing all the 7d autofocus problem made me worry about my own 7d and since I’m a newbie, I need someone here to help me on what sort of test I can perform to determine whether my camera have autofocus problem, can’t seem to find any on the internet.

This will help other new 7d owner as well in determining whether their camera have autofocus problem and immediately returning it if they are problems ASAP. Thanks for the help.
