Look at mister test driven development over here. Hey everyone this guy writes unit tests.
I'm joking here but I think that a lot of people ignore basics like writing unit tests, and that statically typed languages will break a lot more quickly and predictably for people who are lazier, since it enforces structure.
However, I agree with you. Also I think that the people who really push for static typing are the kinds of people who already would write unit tests.
