>>> “Examples” of unit tests suck donkey balls every time.
So lack of good examples imply that the whole system is useless? Yes, an example of "assert True" is useless, but just download any of the thousands of open source projects that use unit tests and look at the code.
>>> They seem to be a great way to spend some extra time doing time consuming, not very hard work.
It's not that time consuming, really. And it being easy work is a good thing. A lot of benefit for easy work!
>>> You have to think about the “evil” business side too.
Running away from your problems is never a good idea. Face the "evil" (whatever that means) side like a man.
>>> Unit tests=more code
OK, there is a difference between useless code and good code. Unit tests doesn't make your system any more complicated or harder to read. In fact, it makes your system more stable and easier to read.
>>> That is mostly because I’m a lazy-ass bastard.
Ah, so we get to the bottom of the problem.
