Well in any case I'm not looking for a large functional test suite at
this stage. It certainly could be useful, but not as a replacement for
unit tests. The latter is for fast verification (so that everyone can
run it as part of 'make tests') and easy identification of the
location of bugs.

These new tests should be written in C, run very quickly (similar to
the existing tests) to verify that the code works. Then when each new
feature is added, the test are expanded to cover the new
functionality. Should the code be refactored, the tests should provide
comfort that nothing broke.
