You can do whatever you like. This is certainly a valid way of
working, and as a testing strategy it would definitely help you to
catch certain kinds of bugs that you might miss with RSpec alone.
However, BDD is about the design process itself, not (just) testing,
and the BDD people (and the RSpec book) recommend a process where you
start at the Cucumber level, i.e. think first about an overall feature
that you want your application to have, and write that feature up as
Cucumber scenarios. Although those scenarios will all fail (because
you haven't written any code yet), they represent what you're aiming
for. To get them to pass you "drop down" into RSpec and write some
more detailed specs for the behaviour you think you'll need to get the
Cucumber scenarios passing, and actually implement the code (to make
the specs pass) as you go. When all the specs pass then the Cucumber
feature will also pass unless you've forgotten something. Then you
move onto writing another Cucumber feature and the design/implement
I'm pretty sure there's a diagram of this process (concentric circles
with arrows) in the first couple of chapters of the RSpec book.
