As soon I sent this email off, I noticed this text in the template:
# Compared to earlier versions of this generator, there is very limited use of
# stubs and message expectations in this spec. Stubs are only used when there
# is no simpler way to get a handle on the object needed for the example.
# Message expectations are only used when there is no simpler way to specify
# that an instance is receiving a specific message.
That explains things a bit, but I'm still curious!
One might argue that the earlier approach (with `mock_model`) may be
better for at least two reasons:
- looser coupling between specs and models
- faster spec execution (ie: don't have to create a real ActiveRecord instance)
I imagine RSpec is treading the fine line between ideal "best
practices" (ie: minimize coupling) and being more pragmatic and easier
to understand by the average developer. What's the current thinking on
