I find the debugger helpful to step through the underlying Rails

The underworld is full of wonderful secrets. Plus, I do make
mistakes and misinterpret and the debugger lets me take a look
around. I try to avoid making bad smells; the debugger is like
Harvey Keitel's character in Pulp Fiction.
What about my other questions? Directions on how to write tests when
a model has_many or belongs_to? When to mock? Pointers to examples
would be the cheap and easy answer -- is there an open source
application with rspec tests?
Ultimately, it's all about how comfortable you feel. Mocks will
always smell bad with rails' associations because of the law of
demeter violations that it promotes. On the other hand, using real
objects and saving to a database can be slow, but at least they give
you some *feel* of the objects - that is, how they will actually be
used in a production system.
One thing that I've realized over the (2) years of testing that I've
done is that testing is just as much about accustoming you to see
relevant error message and their context as it is about getting a
suite green or anything else. When a real bug pops up when
integrating, or on staging, you're almost immediately aware of it's
place and cause. As I've replaced my test suite with mocks and stubs
I find that this is less and less true, and I have less and less
confidence that I'm shipping really solid software.
So, it's always a tradeoff. Bend in the directly you feel more
comfortable.

at the point in my code where I want to break into the debugger.
Then
running the specs via most any means (including autotest, but not
spec_server) will start up the debugger at that point. Frankly,
though, I'll
often just stick in some p statements to show some data. Actually,
I use
this little function:
