I'm attempting to run a couple basic unit tests on an ASP MVC controller, however at one point the controller needs to examine the IPrincipal User object like so:
ViewBag.Level = Security.GetLevel(User); Once the unit test enters the Create controller method, however, the above line throws a NullReferenceException as the User object is null.
Any ideas on how to set an IPrincipal for a unit test session?
Here's the test as I have it written right now. I attempted to access the User object and simply set it before the test goes into the Create method, however the intellisense isn't picking it up.
[Test] public void a06_CloneFromDatabase() { using (AgentResources db = new AgentResources()) { var master = (from a in db.AgentTransmission where a.RecordStatus.Equals("C") select a).FirstOrDefault(); var result = _controlAgtTran.Create(master.ID, null, string.Empty, string.Empty, string.Empty, string.Empty, false) as ViewResult; var model = result.Model as AgentTransmission; Assert.AreEqual(model.ReferenceType, master.ReferenceType); } } EDIT
Following the post mentioned in the comments below I found a method to create a HttpContext session and apply and IPrincipal to that session. This works fine until the unit test moves into the controller where the HttpContext and IPrincipal User objects are all, once again, null.
Since it seems the instance of the controller I'm using has it's HttpContext property as read only (and the IPrincipal User property as well) does anyone know of a way to pass the HttpContext being used in the unit test inside the controller being tested? Also, if this is not possible, what is a usable method for testing RouteValues using ReSharper's unit tests?
