It was already too late.  Knuth vol 3 came out in 1973(?) and its
sorting half is mostly about comparison sorting.

unittest is sort of a clone of JUnit if I understand correctly.
py.test and nose are obscure because they're not in the stdlib.  I
have used unittest a little bit but I mostly use doctest these days.
I have the impression that py.test and/or nose are better in some ways
but I haven't bothered checking further.
