There is a point that has to be stressed - the key to good unit testing is 
your *attitude*. You *have* to start from the assumption that your program 
does have bugs, and that you are going to find *all* them. If you start with 
the (often wrong) assumption that your program is correct (it has no bugs), 
then you end up writing silly tests that don't catch anything. You also have 
to remember that you must keep looking for more bugs after you found a few 
ones. Never allow yourself to become lazy. Be paranoid, be vigilant - 
lazyness toward your own code is a big mistake. Thats one of the reasons why 
it is often easier to spot bugs on someone's else code (and vice-versa 
<grin>).
