[Tutor] automating tests

[Nicholas Wieland]

Hi all,
  I need to automate my unit testing, but before writing something I
want to know if there's something in the library, or if someone has
already solved this problem.
I have a /src and a /tests directory, the /src directory contains the
modules I need to test, the /tests directory, obviously, the tests, in
different files. All my tests use the standard unittest framework.
Can I use test.regrtest, or it's only for internal usage ?

TIA,
  nicholas
