What would this Moq code look like in RhinoMocks

Question

Hey people... trying to get my mocking sorted with asp.net MVC.

I've found this example on the net using Moq, basically I'm understanding it to say: when ApplyAppPathModifier is called, return the value that was passed to it.

I cant figure out how to do this in Rhino Mocks, any thoughts?

var response = new Mock<HttpResponseBase>();
response.Expect(res => res.ApplyAppPathModifier(It.IsAny<string>()))
            .Returns((string virtualPath) => virtualPath);

Answer 1

If you are using the stub method as opposed to the SetupResult method, then the syntax for this is below:

response.Stub(res => res.ApplyAppPathModifier(Arg<String>.Is.Anything))
                .Do(new Func<string, string>(s => s));

Answer 2

Unless I'm misreading the code, I think you can simplify that down quite a bit. Try this:

var response = MockRepository.GenerateMock<HttpResponseBase>();

response.Stub(res => res.ApplyAppPathModifier(Arg<String>.Is.Anything)) 
                        .IgnoreArguments()
                        .Return(virtualPath);

As I mentioned above, sods law, once you post for help you find it 5 min later (even after searching for a while). Anyway for the benefit of others this works:

SetupResult
    .For<string>(response.ApplyAppPathModifier(Arg<String>.Is.Anything)).IgnoreArguments()
    .Do((Func<string, string>)((arg) => { return arg; }));
