running test-suite over https

Trying to further pin down issue #4174 [1], which only occurs with
serf over https (and only on Windows clients I think), I'd like to try
running the test-suite over https. Is there any documentation on that?
I looked in the community guide, in subversion/tests/README and in
subversion/tests/cmdline/README, but didn't find anything.

Getting apache configured with a self-signed cert or with a simple
example cert should be easy enough, but I'm wondering how to get the
test-suite to trust that server cert. Any hints?

checkout / export over https errors out with "svn: E730053: Error
retrieving REPORT (730053)")
