I second the recommendation of nose. It makes it fantastically easy to write
and run unit tests.

Also, in my experience unit tests help reduce bugs in the development
process, but their main benefits are making code more modular (writing for
testing tends to reduce dependencies) and easier to modify (less fear in
refactoring).
