Is there any way to access a Mocked object created from some other factory function.

Suppose I have
class Foo{
public:
 
Foo():mBar{someFactory::createBar(std::string type)}{}

 
void doStuff(){mBar->stuff();}

private:
  std
::unique_ptr<Bar> mBar;
};

class Bar{
public:
 
virtual void stuff(){}
};

class MockBar : public Bar{
public:
 
MOCK_METHOD0(stuff, void());
};

TEST
(Foo,DoStuff){
 
Foo foo;

  EXPECT
_CALL(???, stuff());

  foo
.doStuff();
}

Where someFactory is a factory defined elsewhere that returns subclasses of bar depending on 'type.' Suppose I've managed to get that factory to return a MockBar. Is there any way to get that mock object's address to be able to set expectations?

If you know it is a MockBar, you can just downcast with static_cast<MockBar*>(foo.mBar.get()) and use that pointer.
You might also be reaching a point where mocks don't help you anymore. Maybe a fake can solve your problem?

mBar is private, so I can't just access it like that. I think you may be right that this is a case where there's not much I can do from the google mock suite, but I just wanted to be sure in case someone could think of something (say, for instance, the mock objects register themselves to the test framework somehow that I could access via something like currentTest().getMockedObjects<MockBar>(). (not that any of these exist, but that's the kind of thought)
