class RSpec::Mocks::VerifyingMessageExpectation
A message expectation that knows about the real implementation of the message being expected, so that it can verify that any expectations have the valid arguments. @api private
Attributes
method_reference[RW]
A level of indirection is used here rather than just passing in the method itself, since method look up is expensive and we only want to do it if actually needed.
Conceptually the method reference makes more sense as a constructor argument since it should be immutable, but it is significantly more straight forward to build the object in pieces so for now it stays as an accessor.
