module RSpec::Support::RecursiveConstMethods - rspec 4.0.0.beta1 documentation

const_defined_on? (mod, const_name)

We only want to consider constants that are defined directly on a particular module, and not include top-level/inherited constants.

Given:

class A; B = 1; end
class C < A; end

Then:

C.const_get("Hash") # => ::Hash
C.const_defined?("Hash") # => true
C.const_get("Hash", false) # => raises NameError
C.const_defined?("Hash", false) # => false
C.constants # => [:B]
C.constants(false) #=> []
