Module: Surrogate::ClassMethods

Defined in:
lib/surrogate/endower.rb

Overview

use a module so that the method is inherited (important for substitutability)

#clone ⇒ Object

Should this be dup? (dup seems to copy singleton methods) and may be able to use #initialize_copy to reset ivars Can we just remove this feature an instead provide a reset feature which could be hooked into in before/after blocks (e.g. github.com/rspec/rspec-core/blob/622505d616d950ed53d12c6e82dbb953ba6241b4/lib/rspec/core/mocking/with_rspec.rb)

#new(*args) ⇒ Object

Custom new, because user can define initialize, and we need to record it
