Testing hard - how come ?
Anyone can crash a program - crashing and then telling how You did it and being able to repeat it - that is what I would call the hard part.
And I really hope the software developers of UED are reading this forum as I would not be too surprised if they use the same (and only) source code for the U2 editor as well.
And LAff, You're right, testing SUCKS. It's mostly boring, repetitive and far from creative. And after You have passed a program through a 180 hour test period, the boss comes and drops a phone book on the keyboard - boom goes the program. (seen this happen - called it a "dictionary" test).
