RE: subversion client test suite

I believe Bob was recalling a test harness from our
collective past that did what he said as an option.

That is, ordinarily, the test harness ran everything
within its own framework, connecting to a database
that had the test information, etc. However, the
harness had the option to "export" the test suite
to a collection of files and shell scripts so that
you could run the suite on a minimally-configured
standalone machine. This was especially useful for
performance test suites that generally shut everything
possible down before executing in order to minimize
external effects on the performance of the system.

The harness was known as "TD" and later as "CITE"
(Convex Integrated Test Environment) and was documented
in a few papers I wrote back in the early 90's for
ISSTA and PNSQC. Alas, I have no idea what happened
to this harness after HP baile..., er, sorry, "assimilated",
no that's not right either, um "acquired" that's it
Convex in late 1994.

It was actually a pretty cool harness for its time, though
if I were to build a harness now I would probably embed
Perl into it, rather than the test-specific language
we'd designed then. Perl and Python are great languages
for this sort of thing, personally I prefer Perl, but
that's because I've used it for 12 years (and yes, I
*can* pick up a program I wrote 12 years ago and know
what I was doing, but then, I try to write readable
code, not use the latest whiz-bang ultra-dense
one-liner perl that many perl people tend to extoll).
