Just now, Berhnard and Dominik (Great thanks!) offered me an hour to show
things about OpenQA. The most impressive thing is, besides whole screen
md5sum, OpenQA also has a mechanism to 'imagegrep' if a small piece of image
is inside a whole screenshot.

For example:


Notice the small pictures gallery below the big pictures, they are reference
images for the testing screenshot. If clicking the small scissor icon on the
top left of the screen, people can creat a small piece of the screen and the
system verify tests by the 'imagegrep' method. :)

Best wishes,
