Freebsd test areas or available test suites

[KS]

Hello people,

I have been actively following freebsd mailing list since one week. You are
doing a great job.

I work on small term projects using FreeBSD. I would like to know if you
guys can refer to any test areas/scenarios and/or any available test suites
that are available.

Some areas i have already covered are running operations like cd, del ,
chmod, chown and make use of posix test suite

Can you please point me in right direction for any other information.

Thanks,
KSM
