Hi Cynthia
class_spy doesn’t override the constant automatically, it requires you to add
.as_stubbed_const so it will override the constant when you call it from your
controller. class_spy is essentially class_double.as_null_object, see the docs
here:
https://relishapp.com/rspec/rspec-mocks/v/3-0/docs/verifying-doubles/using-a-class-double
