如何使用rhino mocks在MVC RC1中存根HttpSessionState？

Install-Package Rhino.Mocks

var httpSessionState = MockRepository.GenerateStub<HttpSessionStateBase>();

httpSessionState.Stub(x => x["key"]).Return("value");
httpSessionState.Stub(x => x["key"] = "new value");

var controller = new MyController();
controller.ControllerContext = new ControllerContext(
    new RequestContext(new HttpContextWrapper(HttpContext.Current), new RouteData()),
    controller);
controller.ControllerContext.HttpContext.Stub(x => x.Session).Return(httpSessionState);

var result = controller.MyAction();
Assert.AreEqual("value", controller.ControllerContext.HttpContext.Session["key"]);
