Question

In my interface

public IMyListInterface : IList<IMyItem>
{
void Foo();
}

how can I easily create an example for testing classes that use IMyListInterface.

Currently I’m using GenerateStub<MyListInterface>() and delegating the needed methods / properties to a List<IMyItem> list but it’s tedious.

Currently to get the following code under test to work

foreach (var match in matchList)

I’m doing the following in my test class

IList<IMyItem> baseList = new List<IMyItem>();
IMyListInterface matchList = MockRepository.GenerateStub<IMyListInterface>();

matchList.Stub(m => m.GetEnumerator()).Return(null).WhenCalled(i => i.ReturnValue = baseList.GetEnumerator());

Is there a better way?

Answer 1

Implement the interface in an abstract base class for testing:

public abstract MyMockableList : List<MyItem>, IMyListInterface
{
    public abstract void Foo();
}

You can then use MockRepository.GenerateStub<MyMockableList>(), which will function as a normal list (RhinoMocks won’t override the methods inherited from List<MyItem>) but you can still stub out the Foo() method.
