require 'delegate'

class Parent
  def parent_public; end

  protected

  def parent_protected; end
end

class Child < Parent
end

class DelegatorChild < DelegateClass(Parent)
end

class Parent
  def parent_public_added; end

  protected

  def parent_protected_added; end
end

ignores = Object.public_instance_methods | Delegator.public_instance_methods

p(Child.public_instance_methods - ignores)                 #=> [:parent_public, :parent_public_added]
p(Child.new.public_methods - ignores)                      #=> [:parent_public, :parent_public_added]

p(DelegatorChild.public_instance_methods - ignores)        #=> got: [:parent_public], expected: [:parent_public, :parent_public_added]
p(DelegatorChild.new(Parent.new).public_methods - ignores) #=> got: [:parent_public, :parent_public_added, :parent_protected]], expected: [:parent_public, :parent_public_added]
