my goodness these unittests were/are a mess. most of them didn't do any actual testing, they just made sure things didn't raise an exception

which is fine for some things but not say, i dunno, serialisation code where a mistake could (and does) cause data loss for your users!

oh and mocking the wrong objects so tests look like they do something useful but still pass if you try to break them on purpose

and this fucker writes programming books now!
