An automatic system to check for re-occurring old bugs or missing standards compliance.

See FreeBSD's [http://wikitest.freebsd.org/TetIntegration](http://wikitest.freebsd.org/TetIntegration) for an idea of a structured approach.

During Google Summer of code 2009, I have written a lightweight test case framework along with ~300 test cases. The repository is available here:

http://gitweb.dragonflybsd.org/~beket/pcca-tests.git

In case anyone wants to give it a really quick shot:
$ git clone git://gitweb.dragonflybsd.org/~beket/pcca-tests.git
$ cd pcca-tests
$ cat README | less      # and make sure that the requirements of the
host OS are met
$ ./mktests.sh -sbr

Please let me know of any issue whatsoever you are faced with.
