Stubbing Partial Mocks

[Vyas]

public class EventManager
{
public virutal void SomeMethod()
{
throws new NotImplementedException();
}
}

The partial mock with SomeMethod() stubbed:

EventManager partialMock = new
MockRepository().PartialMock<EventManager>();
partialMock.Stub(x => x.SomeMethod()).Do((Action)
delegate
{
Console.WriteLine("SomeMethod called");
partialMock.Added = DateTime.Now;
}
);
partialMock.Replay();
partialMock.SomeMethod();

Now, the above code works fine calls the stub when SomeMethod() is
called.
The moment I remove 'virtual', the original method is called. Why is
there a restriction that I can ONLY stub 'virtual' methods? What when
I do not have control over the class mocked?

[1. I'm advocating Rhino Mocks in my group for mocking (stub, I
mean :)) pieces under parallel development.
2. They could stub methods they need and the return values they expect
3. Use DI to inject the stub into real code from the Unit Tests]

The inability to Stub non-virtual methods gets in the way. Any
thoughts?

PS: The below doesn't work as well:

EventManager partialStub =
MockRepository.GenerateStub<EventManager>();
partialStub.Stub(x => x.SomeMethod()).Do((Action)
delegate
{
Console.WriteLine("SomeMethod called");
partialStub.Added = DateTime.Now;
}
);
partialStub.Replay();
partialStub.SomeMethod();

Please read the FAQ for the reasons.

Hm... I did find out it's Castle DynamicProxy's limitation (and
CLR's)...
I was wondering if there is a possibility of doing:

//Pseudo Code
IEventManager manager =
MockRepository.GenerateStub<IEventManager>(new EventManager()); //
Supply original object
manager.Stub(x=>x.SomeMethod()).Return(delegate() { //Do something
here }); //Stub the method that throws expection

Right now, I suspect, I need to mock the interface and stub all the
methods and route the calls to the original object manually.
This could be cumbersome if the class being stubbed has too many
methods/properties.

Feel free to provide a patch to add this capability

[Vyas]

Absolutely.... Will try this weekend...

Here's the complete approach outlined...

Hope to get started on the patch later this week...
