I also noticed that (at least in the code I write) bugs are much more prevalent in "boring code" than in "smart code"; that is, if I got some elegant but rather advanced piece of code I had put a lot of thought into (like some smart math stuff or something similar), it almost always works right away without any bugs whatsoever, however, boring and tedious-to-write code (such as wiring up GUI, integration glue code etc) tends to have a lot more bugs in it. Unfortunately, this first type of code is a lot easier to test automatically than the second type. Smart code usually has clean and simple interfaces, while writing tests for "boring code" is also boring and tedious, like writing a test for each textbox on a form etc.
