The way I have done what SQLUnit does in Python is for my suite to
create a test database (yes a real one), load up some data in setUp(),
call the stored procedure, make some selects to assert it did the
right thing, then delete the data in tearDown().  I even created a
module to help with the setup/teardown/assertion part :
http://code.google.com/p/fixture/ ... however, it is slightly annoying
because you have to use an ORM (sqlalchemy, sqlobject) and that can
impose some limitations and complications.  I also have an unfinished
work branch supporting sqlalchemy 0.4, hopefully it will be released
soon.  Anyway, this is just a concept.  You can still accomplish this
without using the fixture module.  Just put SQL insert statements in
your setUp() and delete statements in tearDown().  At work we do have
a test suite in Python entirely dedicated to stored procedures and
triggers that maintain fact tables and other data warehouse / star
schema type of stuff.
