I agree with you. This is certainly how I work with my AR classes.
However there's a big difference in maturity between AR and ARes.
ARes isn't even "official" yet. So while with AR I can mock
MyClass.find and know that AR does the right thing, I'm not entirely
sure with ARes. I don't know how it's going to parse an XML document.
Turns out it did some funky things and I couldn't use it.
Once I had one spec that demonstrated ARes worked for my purposes, I'd
just mock out all subsequent specs.
