From d4e7ca034cbbe29911b08eb5c252aa0d05b6a429 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Thu, 30 Aug 2018 22:40:07 +0000 Subject: Add unit test for AutoRestorer<> on smart pointer types. Test UnownedPtr<> and RetainPtr<>. We cannot operate against std::unique_ptr<> because we need a copyable type. Add test for self-reassignment on going out of scope. Move one test helper class to testing/ so it can be shared among unit tests. Allow it to recognize if it ever gets "destroyed", otherwise we can't be sure Retain/Release applied in the correct order.
