Strangely I have never had a problem testing stored procedures.  You have
to create a data set for the tests of course and that is the hardest part,
but there are some really nice things:

1.  If your test scripts always roll back you can run them on a production
database as a troubleshooting step
2.  It is easy to hook things up to a TAP harness (whether using PgTAP or
some hand-rolled solution).  I think it would be harder to connect to xunit
though.  So use TAP ;-)
3.  I usually create a test results table (in my test case, rolled back
after!) which stores the test description and pass status.  That makes it
easy to check using other tools.

Usually I set aside a range of things (negative id's for example) for
testing purposes.
