Third Shelf

A while back on StackOverflow I asked a question on how to create a mock object with Rhino Mocks that implements multiple interfaces. In other words, I want to generate a mock that implements more than one interface. This baffled me for a while and I was shown the light by one of my colleagues.

A multi-mock is created like so:

var mocker = new MockRepository();
var mock = mocker.CreateMultiMock<IPrimaryInterface>(typeof(IFoo), typeof(IBar));
mock.Expect(x => x.AnswerToUniverse()).Return(42);
mocker.ReplayAll();
