OCMock Partial mock only for descendant class

I'm trying to set some unit test in our huge project. The problem is that some ViewControllers when called partial mock crash with following trace:

error: -[EspionageViewControllerTests testFillEspionageTabInfo] : failed: caught "NSInternalInconsistencyException", "-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "EspionageViewController" nib but the view outlet was not set."

As I understand I had problems with setTopBarView, and especially a place where I made following:

[viewElement setFrame:CGRectMake(viewElement.frame.origin.x, self.view.bounds.origin.y - viewElement.frame.size.height , viewElement.frame.size.width, viewElement.frame.size.height)];

So the self.view call makes this crash. My question is how can I avoid this situation - especially when my EspionageViewController is subclass of another ViewController where setTopBarView is defined. I need to use OCMPartialMock on EspionageVC as otherwise I won't be able to check it's methods, however it's super class(and methods) must be fully mocked to prevent those crashes. Any help will be apreciated.
