Haha, very funny.
It's a good thing there are so many jokes hidden inside the image.
We could add a couple/many more:
self deny: 1 = 2. self deny: 1 = -1. self deny: (4 / 2) = 3 self shouldnt: [ 1 / 2 ] raise: ZeroDivide
;-)
Yes it's laughable. However, I recently hacked Intger/Fraction to speed up mixed operations and guess what... once you know the miserable error's we can make... Nicolas

The middle part is a GREAT example of a useful unit testâ¦
that's called a negative test :D, assume what possible could fail in the universe and test for it :D
I will write a paper on automatic negative test generation. Who wants to join? :-)
You can even write a program that write a paper about negative tests generation ;-)
