Mocking Methods Only

[Luke]

I've been struggling with this for a couple hours now and for the life
of me can't figure out how to make it work.

Here's the case:
The presenter has a call
this.view.programs=RequestPrincipal.Current.GetPrograms;
The RequestPrincipal class is something that is very cumberson to mock
and etc but all it does is return a CustomTypeArray[] so I'm trying to
figure out if I can do something like this:
Expect.Call(RequestPrincipal.Current.GetPrograms).Return(dummyCustomTypeArray);

The issue that I get is "System.NullReferenceException: Object
reference not set to an instance of an object.." because
RequestPrincipal is not created anywhere. Is there another way of
doing this? Just setting up an expected call to some method on a
not-mocked object and explicitly telling it to return a result.

Thanks so much,
Luke

You need to set the expectation on Current, not GetPrograms.
RequestPrincipal is what you are mocking, no?

No. Mocking Request Principal has its own issues (no default
constructor and etc). I'm trying to see if there's a way to simply
say if someone calls SomeUnMockedObject.GetMeAList() if there is a way
to simply set an expectation for that call to always return
List<Whatever> SomeEmptyList without actually mocking or instantiating
the SomeUnMockedObject.

I would probably extract an interface somewhere and pass that instance into my presenter.  RequestPrincipal.Current looks like a service locator call which I like to avoid anyway.

Unfortunately this is not something I can do (this is a big team
project). So I was trying to find a way to test just my stuff without
having to create additional interfaces and etc.

Wrap, then mock.. or make an adapter.. or resort to typemock or some
other IL weaving... I would do the former.
