What’s the best way to test that all assocaitions are preloaded when a  
method is called?

For example, do\_something is a method that makes a db call and preloads  
several associations. Is there a way to write a test that checks that  
calls to do\_something only make one db call?

On the functional level is there a way to write tests that check that  
actions only trigger a certain number of db queries (counting only loads  
and not the select column queries).

Cheers, Ray
