3 # This spec was generated by rspec-rails when you ran the scaffold generator.
4 # It demonstrates how one might use RSpec to specify the controller code that
5 # was generated by Rails when you ran the scaffold generator.
7 # It assumes that the implementation code is generated by the rails scaffold
8 # generator. If you are using any extension libraries to generate different
9 # controller code, this generated spec may or may not pass.
11 # It only uses APIs available in rails and/or rspec-rails. There are a number
12 # of tools you can use to make these specs even more expressive, but we're
13 # sticking to rails and rspec-rails APIs to keep things simple and stable.
15 # Compared to earlier versions of this generator, there is very limited use of
16 # stubs and message expectations in this spec. Stubs are only used when there
17 # is no simpler way to get a handle on the object needed for the example.
18 # Message expectations are only used when there is no simpler way to specify
19 # that an instance is receiving a specific message.
