This look like a very good starting point.  I'm investigating it now.
One thing that surprised me was the fact that you seem to be using a
home made test suite system instead of using the official one included
in python.  Why is this?  Unless you have a very good reason, I
suggest we rewrite it to use the unittest python module,
<URL:>.  This will give
us the system to run all tests at once and give a summary at the end
of all these tests.

Yes, this look like a better starting point that the mapserver/tests/
scripts, and I will start here.  I'll start by trying to understand
the current tests, and see how much code coverage they provide.

This patch will make it easier to enable coverage testing using a new
--enable-coverage configure flag.
