Unit tests are a huge win, even with statically typed languages. 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.
