NovaProva

NovaProva is a unit testing framework for C (and later C++). In other
words it discovers tests, runs them in various ways, detects failures
in them, and reports the failures out to a human.

There are many other such frameworks for many languages, see
http://en.wikipedia.org/wiki/XUnit Notably, we use the CUnit today
in the Cyrus IMAP server, and it was CUnit's many pain points that
inspired my work on NovaProva.
