Given that pretty much any software to come out of Google is usually
pretty overweight, in particular on dependencies:

In the V(arnish)Test tool we built a facility for interactive and
curses-based tests using teken, (which we got from FreeBSD):

	https://github.com/vtest/VTest

The code for that sub-part lives in:

	https://github.com/vtest/VTest/blob/master/src/vtc_process.c

Here is a typical test-case using it:

	https://github.com/varnishcache/varnish-cache/blob/master/bin/varnishtest/tests/u00008.vtc

The verbose output from that test can be seen here:

	http://phk.freebsd.dk/misc/u00008.txt

V(arnish)Test is a modular program, and if you leave out all the
HTTP related modules, and substitute 'sbuf' for 'vsb', and "TAILQ" for "VTAILQ"
it would fit nicely into FreeBSD.

Never attribute to malice what can adequately be explained by incompetence.
