Hooking Up Unit Tests to Local IIS Web Instance - asp.net-mvc

Question

I'm trying to run unit tests for a project which is reliant on the web instance as it uses integrated windows authentication to verify the current user. When I run the tests it doesn't fire up the web instance, which is expected, but I need it to in order for any tests to succeed really. Anyone have any idea of how to do this?

Okay, I got this working in the end. You have to mock HttpContextBase (which is preferential over HttpContext I hear) and then set up your IPrincipal which is returned from the mock object. I'll give the full code listing so you get the idea:
[TestInitialize]
public void SetUp()
{
userRepositoryMock = new Mock<IUserRepository>();
controller = new AccountController(userRepositoryMock.Object);
httpContextMock = new Mock<HttpContextBase>();
IPrincipal fakeUser = new GenericPrincipal(new GenericIdentity("johnsmith#johns4232mith.com", "Forms"), null);
httpContextMock.Setup(x => x.User).Returns(fakeUser);
var context = new Mock<HttpContextBase>();
var request = new Mock<HttpRequestBase>();
var response = new Mock<HttpResponseBase>();
var session = new Mock<HttpSessionStateBase>();
var server = new Mock<HttpServerUtilityBase>();
var identity = new Mock<IIdentity>();
request.Setup(req => req.ApplicationPath).Returns("~/");
request.Setup(req => req.AppRelativeCurrentExecutionFilePath).Returns("~/");
request.Setup(req => req.PathInfo).Returns(string.Empty);
response.Setup(res => res.ApplyAppPathModifier(It.IsAny<string>()))
.Returns((string virtualPath) => virtualPath);
identity.SetupGet(ident => ident.IsAuthenticated).Returns(true);
context.Setup(ctx => ctx.Request).Returns(request.Object);
context.Setup(ctx => ctx.Response).Returns(response.Object);
context.Setup(ctx => ctx.Session).Returns(session.Object);
context.Setup(ctx => ctx.Server).Returns(server.Object);
context.Setup(ctx => ctx.User).Returns(fakeUser);
controller.ControllerContext = new ControllerContext(context.Object, new RouteData(), controller);
}
