If I've got something like def find_recent(limit = 5) find :all, :order => "created_at DESC", :limit => limit end I think it's better to just create 6 records and make sure it returns the proper 5. Then write another spec that only gets 3. I suppose you could use a mock db that ensures that the SQL is valid...but that seems brittle. Also at some point you have to ensure that the generated SQL actually works (by running it). Might as well do that in the spec itself. Also that's a better way because the behavior you want in this case is for it to find the proper records, not to generate some particular SQL string.
