With ASP.NET/MVC + MvcMockHelpers + RhinoMocks, which sets RouteData?
I am trying to write a test for an ASP.NET MVC controller method. I have RhinoMocks (since it seems to be the most popular and best), and MvcMockHelpers (since I think I need what).
My validation method looks like this:
var controller = new MyController();
MvcMockHelpers.SetFakeControllerContext(mocks, controller);
mocks.ReplayAll();
var result = controller.MyAction(arg1, arg2);
// then i'd make assertions on the result
This doesn't work because the RouteData parameter has no entries, and MyAction depends on having a set of values such as "controller" and "action".
I know I can create a custom RouteData for every controller method I want to call, but that seems silly. What part of ASP.NET MVC is responsible for setting this up and how can I get into this code path?
(I feel completely lost here, so if I bark on the wrong tree, let me know that too.)

I suggest you split device testing into routing tests and controller tests. Routing tests will test routes regardless of controllers. This allows you to test your controllers in a traditional way like any other Plain Old CSharp method.
Phil Haack and Adam Tibor have good articles on how to check your routes:

You may be interested in the way to create and test CodeCampServer routes.
RouteConfigurator: (note that it cleans up routes every time RegisterRoutes () is called - required for the MVCContrib route validation helper) http://code.google.com/p/codecampserver/source/browse/trunk/src/UI/ RouteConfigurator.cs

Viewing the source of this project (among other things) answered many questions for me, and I would recommend that you download the source and look around the unit tests project if nothing else.
