i've finished with this spec
public abstract class Specification <C> where C: Controller{ protected C controller; HttpContextBase mockHttpContext; HttpRequestBase mockRequest; protected Exception ExceptionThrown { get; private set; } [SetUp] public void Setup() { mockHttpContext = MockRepository.GenerateMock<HttpContextBase>(); mockRequest = MockRepository.GenerateMock<HttpRequestBase>(); mockHttpContext.Stub(x => x.Request).Return(mockRequest); mockRequest.Stub(x => x.HttpMethod).Return("GET"); EstablishContext(); SetHttpContext(); try { When(); } catch (Exception exc) { ExceptionThrown = exc; } } protected void SetHttpContext() { var context = new ControllerContext(mockHttpContext, new RouteData(), controller); controller.ControllerContext = context; } protected T Mock<T>() where T: class { return MockRepository.GenerateMock<T>(); } protected abstract void EstablishContext(); protected abstract void When(); [TearDown] public virtual void TearDown() { }} and the juice is here
