Agreed - if it's in the session, this should be the preferred way.

I don't have any experience with RSpec/Rails using a database - my
current Rails project is DB-less :-) But on a recent C# project (with
NUnit) I've chosen to just use a database in my tests. It wasn't even an
in-memory database (embedded Firebird) but it was still fast enough with
several hundred tests hitting the database. Rails with SQLite in memory
should even be faster. So speed isn't really much of an issue in my

But you're right that stubbing database access should be preferred.
Sometimes it's just easier to put complex data into a fixture and
retrieve it from the database. Maybe that's a design smell - I'll keep
this in mind when I run into this situation the next time.
