How can I test methods which needs user to be logged

问题

I'm testing some code which needs user to be logged in. When I'm trying to log in with AccountController, it's looks like everything is working, but at AccountController (IPrincipal) User is still null. How can I properly log in (or better, can I mock it somehow)?

public async Task SetupAsync()
        {
            var context = new DataContext();
            var manager = new UserManager(new UserStore(context));
            var accountController = new AccountController(manager);
            var mockAuthenticationManager = new Mock<IAuthenticationManager>();
            mockAuthenticationManager.Setup(am => am.SignOut());
            mockAuthenticationManager.Setup(am => am.SignIn());
            accountController.AuthenticationManager = mockAuthenticationManager.Object;
            var user = new LoginViewModel
            {
                Email = "user@wp.pl",
                Password = "useruser",
                RememberMe = false
            };
            if (manager.FindByEmail("user@wp.pl") == null)
            {
                await manager.CreateAsync(new User { Email = "user@wp.pl", UserName = "user@wp.pl" }, "useruser");
            }
            await accountController.Login(user, "home/index");
            _calendarController = new CalendarController(context);
        }

Here I got User null exception:

public ClaimsPrincipal CurrentUser
        {
            get { return new ClaimsPrincipal((System.Security.Claims.ClaimsPrincipal)this.User); }
        }

Edit: At return line, I have still User property null. This is sample from AccountController:

var user = await _userManager.FindAsync(model.Email, model.Password);

            if (user != null)
            {
                await SignInAsync(user, model.RememberMe);
                return RedirectToAction("index", "calendar");
            }

回答1:

You should mock your _userManager, and use a mock setup for when the method FindAsync is called. Then you return a fake user you can use later in the code

Figured it out on my own, probably not elegant solution but I'm happy anyway. @andreasnico your answer helped, thanks.

I'm mocking my custom ClaimsPrincipal, and setting up UserId - that's what I really needed.

var mockCp = new Mock<IClaimsPrincipal>();
mockCp.SetupGet(cp => cp.UserId).Returns(user.Id);
_calendarController.CurrentUser = mockCp.Object;
