Mocking the ASP.NET HttpSession with Rhino Mock

gistfile1.cs

public void SetUpSession()
{
	// Arrange
	var httpContext = MockRepository.GenerateStub<HttpContextBase>();
	var httpSession = MockRepository.GenerateStub<HttpSessionStateBase>();
									   
	httpContext.Stub(h => h.Session).Return(httpSession);
	mock.Setup(p => p.HttpContext.Session).Returns(mockSession.Object);

	// Now create the system under test
	var repository = MockRepository.GenerateMock<Repository>();
	var controller = new CustomerController(repository);
	var controller.ControllerContext = new ControllerContext(httpContext, new RouteData(), _controller);
 
	controller.Create();

	// Assertions
	Assert.AreEqual("testuser1", controller.HttpContext.Session["Username"]);
