asp.net-mvc – 使用AutoMapper的控制器上的单元测试

我正在尝试单元测试使用AutoMapping的UpdateUser控制器.这是控制器的代码

UpdateUserController

private readonly IUnitOfWork _unitOfWork;
    private readonly IWebSecurity _webSecurity;
    private readonly IOAuthWebSecurity _oAuthWebSecurity;
    private readonly IMapper _mapper;

    public AccountController()
    {
        _unitOfWork = new UnitOfWork();
        _webSecurity = new WebSecurityWrapper();
        _oAuthWebSecurity = new OAuthWebSecurityWrapper();
        _mapper = new MapperWrapper();
    }

    public AccountController(IUnitOfWork unitOfWork,IWebSecurity webSecurity,IOAuthWebSecurity oAuthWebSecurity,IMapper mapper)
    {
        _unitOfWork = unitOfWork;
        _webSecurity = webSecurity;
        _oAuthWebSecurity = oAuthWebSecurity;
        _mapper = mapper;
    }

    //
    // Post: /Account/UpdateUser
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult UpdateUser(UpdateUserModel model)
    {
        if (ModelState.IsValid)
        {
            // Attempt to register the user
            try
            {
                var userToUpdate = _unitOfWork.UserRepository.GetByID(_webSecurity.CurrentUserId);
                var mappedModel = _mapper.Map(model,userToUpdate);

 **mappedModel will return null when run in test but fine otherwise (e.g. debug)**


                _unitOfWork.UserRepository.Update(mappedModel);
                _unitOfWork.Save();

                return RedirectToAction("Index","Home");
            }
            catch (MembershipCreateUserException e)
            {
                ModelState.AddModelError("",ErrorCodeToString(e.StatusCode));
            }
        }
        return View(model);
    }

这是我的单位测试
UpdateUserControllerTest

[Fact]
    public void UserRepository_Update_User_Success()
    {
        Controller = new AccountController(UnitOfWork,WebSecurity.Object,OAuthWebSecurity.Object,Mapper);
        const string emailAsUserName = "user@username.com";
        const string password = "password";
        const string email = "email@email.com";
        const string emailNew = "newEmail@email.com";
        const string firstName = "first name";
        const string firstNameNew = "new first name";
        const string lastName = "last name";
        const string lastNameNew = "new last name";

        var updatedUser = new User
            {
                Email = emailNew,FirstName = firstNameNew,LastName = lastNameNew,UserName = emailAsUserName
            };

        WebSecurity.Setup(
            s =>
            s.CreateUserAndAccount(emailAsUserName,password,new { FirstName = firstName,LastName = lastName,Email = email },false))
                   .Returns(emailAsUserName);
        updatedUser.UserId = WebSecurity.Object.CurrentUserId;

        UnitOfWork.UserRepository.Update(updatedUser);
        UnitOfWork.Save();

        var actualUser = UnitOfWork.UserRepository.GetByID(updatedUser.UserId);
        Assert.Equal(updatedUser,actualUser);

        var model = new UpdateUserModel
            {
                Email = emailAsUserName,ConfirmEmail = emailAsUserName,FirstName = firstName,LastName = lastName
            };
        var result = Controller.UpdateUser(model) as RedirectToRouteResult;
        Assert.NotNull(result);
    }

我有一个直觉,当在测试模式下运行时,映射器不会查看我在Global.asax中设置的映射器配置.因为错误只在执行单元测试时发生,而是在运行网站时才发生.我已经创建了一个IMappaer接口作为DI,所以我可以模拟它进行测试.我使用Moq for Mocking和xUnit作为测试框架,我还安装了我还没有使用的AutoMoq.任何想法？谢谢你看我的冗长的职位.希望有人可以帮忙,一直在抓我头上好几个小时,阅读很多帖子.

解决方法

如果要在测试中使用真正的AutoMapper实现,那么您需要首先进行设置.您的测试不会自动接收您的Global.asax,您也必须在测试中设置映射.当我进行集成测试时,我通常会在测试夹具设置中调用一个静态AutoMapperConfiguration.Configure()方法.对于NUnit,这是[TestFixtureSetUp]方法,我认为xUnit你只是把它放在构造函数中.
