Question about KYUA

I am working on a video about comparing POSIX conformance testing between
FreeBSD and Linux (yeah I know Linux Posix is a joke gone Meme).  I keep
getting these people say Linux is Posix compliant...LOL. I am curious, does
Kyua play any part in testing for POSIX conformance?

I noticed when I ran it sure is comprehensive with the tests it
performs...very nicely done

Thanks in advance.
