I agree the current use is ...useful, but having a persistent test
directory could be useful, too. As long as the tree is only used for
testing and remains "pristine", it should work well. The one hangup
I see is with old auto-generated files interfering with new ones, but
that could be a problem with the code.

You assume that files being managed need to be compiled to be tested. :)
My biggest project I want to manage is in Perl. Our test suite is a
little different: Because the code comprises a website, our tests use
a Perl-based web browser to 'visit' a copy of the website and test how
the code runs under Apache/mod_perl.
Also, there are some 10 MB movies setting in the tree, which can take
some time to copy.
But OK, yes, it still takes a lot longer to run the tests than to copy
