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("[e-mail]", "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);
}
