| Unit Tests -- just do it!

Been coding a lot these days on SmallWorld.
I try to be disciplined and continue adding unit tests to the hundreds of
unit tests wherever sth. could go wrong, but ever again I go off the track
and code several methods and even entire classes without any tests.
It’s simple stuff and hey, this is ruby :-).
Then I sit here for 3 hours trying to understand why the dammed computer
does not do what it should. It’s that feeling I hate most. You waste
time .. I mean I could as well go skiing or drink a bottle of vodka ..
would be about the same productivity progress on my code and at least I
would enjoy the sun.
After hitting my head long enough and starting to isolate the stuff .. I
found it .. I had forgotten one return in a most trivial three line long
method. Shame on me. Now I will go back to being test-infected. test-first
is even better. Dammit .. sorry for the rant, but I doubt there are many
systems like computers where one comma at the wrong place can make
everything go boom. Oh well, try to modify the DNA and do not know what you
are doing. :-).
