In this case, you are relying on what installed program or function is called when you invoke uuid in the shell. It seems reasonable to me to check if it is having sensibly, if the reliability of your program counts on it. I have no idea what dodgy uuid programs you might find installed.
You could just as do stuff like "int x=1; assert(x == 1);" and so on. And it would be just as futile.
