If ArticleSearchCriteria has virtual members, I think you could mock
the ServiceAreas collection and set an expectation on the "Add"
method. Assuming you have something like this:
class ArticleSearchCriteria
{
public virtual IList<ServiceArea> ServiceAreas { get; set; }
}
You could create a mock IList<ServiceArea> and set an expectation on
the Add method. Then stub ArticleSearchCritera.ServiceAreas property
to return your mocked IList<ServiceArea> (below is AAA syntax and
typed on-the-fly):
var saList = MockRepository.GenerateMock<IList<ServiceArea>>();
var searchCriteria = MockRepository.GenerateStub<ArticleSearchCriteria>();
s.ServiceAreas = saList; // I think you can just do the assign with AAA syntax
Now tell Rhino mocks you expect an Add of your resultFromDAO:
saList.Expect(c => c.Add(resultFromDAO));
I think that'll get you going.
