It depends on how clearly you want to isolate from the database. Your first
example is going to hit the DB 37 times. I wouldn't do that personally. Even
if I was hitting the database I'd reduce that dataset to one or two records.
The way I'd approach this if I were trying to isolate from the DB would be
like this:
@company = mock_model(Company)
Company.should_receive(:basecamp_fetch).
with("companies").
and_return([EMAIL PROTECTED])
# ... expectations about @company
