We now automatically set a responder on mock object which are used for partial mocks. Having made the change above, I had to set include_all to true for the call to Object#respond_to? in Mock#check_responder_responds_to in order to fix a load of broken tests. The legacy_behaviour_for_array_flatten condition in Mock#check_responder_responds_to is needed to avoid a regression of #580 in Ruby < v2.3. Hopefully this is a small step towards having Configuration.prevent(:stubbing_non_existent_method) check Method#arity and/or Method#parameters (#149) and rationalising Configuration.stubbing_non_existent_method= & Mock#responds_like (#531).
When a method doesn't accept keyword arguments. In this scenario keyword or Hash-type arguments are assigned as a single Hash to the last argument without any warnings and strict keyword matching should not have any effect. This is an exploratory spike on fixing #593. * This has highlighted a significant problem with partial mocks in #532. The method obtained from the responder is the stub method defined by Mocha and not the original. This effectively makes it useless! * I'm not sure the method_accepts_keyword_arguments? belongs on Invocation, but that's the most convenient place for now. It feels as if we need to have a bit of a sort out of where various things live and perhaps introduce some new classes to make things clearer. * We might want to think ahead a bit at what we want to do in #149 to decide the best way to go about this. * I'm not sure it's sensible to re-use the Equals matcher; we could instead parameterize PositionalOrKeywordHash, although the logic in there is already quite complex. Conversely if this is a good approach, it might make more sense to do something similar when creating a hash matcher for a non-last parameter to further simplify the code. * I haven't yet introduced any acceptance tests for this and I suspect there might be some edge cases yet to come out of the woodwork. In particular, I think it's worth exhaustively working through the various references mentioned in this comment [1]. [1]: #593 (comment)
