Question

I read some of the answers on here re: testing views and controllers, and mocking, but I still can’t figure out how to test an ASP.NET MVC controller that reads and sets Session values (or any other context based variables.) How do I provide a (Session) context for my test methods? Is mocking the answer? Anybody have examples? Basically, I’d like to fake a session before I call the controller method and have the controller use that session. Any ideas?

Check out Stephen Walther’s post on Faking the Controller Context:

ASP.NET MVC Tip #12 – Faking the Controller Context

[TestMethod] public void TestSessionState() {     // Create controller     var controller = new HomeController();       // Create fake Controller Context     var sessionItems = new SessionStateItemCollection();     sessionItems['item1'] = 'wow!';     controller.ControllerContext = new FakeControllerContext(controller, sessionItems);     var result = controller.TestSession() as ViewResult;       // Assert     Assert.AreEqual('wow!', result.ViewData['item1']);      // Assert     Assert.AreEqual('cool!', controller.HttpContext.Session['item2']); }
