"""Test cases for objects implementing IDataManager.

This is a combo test between Connection and DB, since the two are
rather incestuous and the DB Interface is not defined that I was
able to find.

To do a full test suite one would probably want to write a dummy
storage that will raise errors as needed for testing.

I started this test suite to reproduce a very simple error (tpc_abort
had an error and wouldn't even run if called).  So it is *very*
incomplete, and even the tests that exist do not make sure that
the data actually gets written/not written to the storge.

Obviously this test suite should be expanded.
