You need not have doctest as a part of source code. You can also create a separate documentation file that contains prose as well as tests intervening. http://www.python.org/doc/lib/doctest-simple-testfile.html Combine it with ReStructured Text and you have a wonderful documentation and testing solution in one place. Personally, I like this a lot better than Javadoc style documentation where usage examples are often absent. > Also Wikipedia article contains some "Cons of doctest" that look pretty nasty: Of course, doctest is hardly the ultimate testing solution.

I have seen enough libraries that use doctest. Zope, Twisted and Paste are some of the popular Python projects in that use it. Epydoc supports it as well. -- http://mail.python.org/mailman/listinfo/python-list
