Mocking methods on an Generic Interface

Hi,

You can replace the behavior of the interface using a fake instance and set the DoInstead() behavior on that. You can do that for an IInsertionIdFactory which has the generic parameter defined:

var fake = Isolate.Fake.Instance<IInsertionIdFactory<Person>>();
Isolate.WhenCalled(() => fake.SetNewId(null, null, null)).IgnoreCall();

However, this cannot be done if you don't define what TEntity you're working on. Defining behavior for any generic parameter is not currently supported - it's an interesting feature request so I'll log it in our backlog.

Thanks,
Doron
