In my experience the main benefit of the unittests is not to determine
whether a newly introduced feature has an error, but rather to keep
subsequent contributors (with less expertise/knowledge of the code)
from breaking it. I tend to think of it as a contract between myself
and future developers. For instance, when making substantial changes
to scipy.sparse I found the unittests to be immensely helpful in
expressing the intentions of the previous authors.

I can say from personal experience that you're not the first to be
reprimanded by Stefan about unittests :)
