-# This spec was generated by rspec-rails when you ran the scaffold generator.

-# It assumes that the implementation code is generated by the rails scaffold
-# generator.  If you are using any extension libraries to generate different
-# controller code, this generated spec may or may not pass.
-#
-# It only uses APIs available in rails and/or rspec-rails.  There are a number
-# of tools you can use to make these specs even more expressive, but we're
-# sticking to rails and rspec-rails APIs to keep things simple and stable.
-#
-# 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
