i think that there is some misconception here from the people who says
that "unittests are almost useless". such people wants unittests to
catch *all* bugs. and when unittests fails at that, people making the
conclusion that unittests are not useful at all.

the other thing is that having all unittests separated from the actual
code is PITA, at least for me. i really love D unittest feature, thanks
to it i wrote alot more unittests in my D code than in the code in
other languages i'm using. and having ddoc in compiler encourages me to
write at least a minimal documentation for the source. ;-)

yes, i know about doxygen, unittesting frameworks and so on. somehow
they never works for me. "ah, those tools are second class citizens,
i'll do 'em favor later." of course, that "later" means "never" most of
the time. ;-)

and what i also can't grok is "test-driven developement". ah, we spent
alot of time writing that tests that we can't even run 'cause we didn't
start working on the actual code yet. it's splendid! we didn't start
the real work yet and we are already bored. i don't believe that this
is a good way to develop a good project.
