Note to self (and anybody else trying this) : You need to populate the
results in order for this to work :) d'oh.

Because I'm interested in checking that the generated query is ok -
and the results don't necessarily tell me that - so I need to see the
statement and parameters provided.
Basically, I'm using Traits (via Class::Trait) to add specialised
searching to classes in an application, these traits generate and run
complex queries using SQL::Abstract, and return a CDBI iterator (or
multiple cdbi iterators concatonated and wrapped in an iterator with
the same API).
It is much easier to test both the iterator and the query generation
if I can pre-populate the results and control whats going on without
having to worry about creating and populating a test database and
replicating all kinds of horrid geographical stuff.
Anyway - sorted now and making great progress with my testing.. once
I've mocked all the queries I'm going to mock TT.
