#14 NMock2: Mock object can't be passed as an object parameter
I am trying to use NMock2 with Windows Workflow
Foundation. For WF, I've defined an interface such
as the following:
[ExternalDataExchange]
public interface IMyService {
void DoSomething();
}
Inside of my test code, I'm getting a mock object
using something like the following code:
IMyService mockService =
mockery.NewMock<IMyService>();
At this point, the mock object appears to be fine and
the following condition is met:
mockService is IMyService == true
The ExternalDataExchangeService class in WF, has a
method named AddService that I need to pass my mock
object to in order to allow the workflow to call my
service. The signature for AddService is:
void AddService(object service)
When I pass my mock object to AddService() or to any
other method that accepts a System.Object type as a
parameter, the mock object doesn't appear to
implement the interface in the called method.
Basically, in the called code:
mockService is IMyService == false
This works with NMock v1, and I think it's related to
the use of transparent proxies in NMock v2.
I can be contacted at

This is true of any IServiceContainer as well. Currently I
don't have access to my code, but I'll upload a patch
against this bug that I had to fix for my internal
projects. I have unit tests for my issue, but it would be
nice to know if it fixes your issue as well.

This should be fixed, although I would not want to attach a dependency to the workflow libraries to the main set of tests. If someone with a knowledge of the WF can create a stand-alone test to verify this I'd appreciate it.
