控制器方法不返回最小起订量数据

Question

我正在尝试为控制器编写单元测试方法，但是我用测试数据嘲笑的方法不会返回它。

我的控制器：

IDataService _dataService = new DataService();

        [HttpPost]
        public JsonResult VerifyCredentialsAndGetUserData(string email, string password)
        {
            return Json(this._dataService.VerifyCustomerAndReturnHisID(email, password), JsonRequestBehavior.AllowGet);
        }

其中存在方法VerifyCustomerAndReturnHisID的我的图书馆：

 public int VerifyCustomerAndReturnHisID(string email, string password)
        {
            var emailToCheck = new SqlParameter("@Email", email.ToLowerInvariant());
            var pass = new SqlParameter("@Password", password);

            var result = dbContext.Customer.SqlQuery("SELECT * FROM Customer WHERE Email = @Email AND Password = @Password", new SqlParameter("@Email", email.ToLowerInvariant()), new SqlParameter("@Password", password)).ToList();
            if (result.Count() > 0)
            {
                return result.FirstOrDefault().ID;
            }
            else
            {
                return 0;
            }
        }

我的测试方法：

[TestMethod]
        public void VerifyCredentialsAndGetUserData()
        {
            var user = new ApplicationDatabase.DB_Models.Customer()
            {
                Email = "basejohn@test.pl",
                Password = "testPass",
                ID = 12
            };
            var mock = new Mock<DbContext>();
            var userDbSet = new ApplicationDatabase.DB_Models.FakeDbSet<ApplicationDatabase.DB_Models.Customer>();
            userDbSet.Add(user);

            this._IdataServiceMock.Setup(x => x.VerifyCustomerAndReturnHisID(It.IsAny<string>(), It.IsAny<string>())).Returns(user.ID);
            var a = this._IdataServiceMock.Object.VerifyCustomerAndReturnHisID(user.Email, user.Password); // <-- this will return 12

            var result = this.loginPannel.VerifyCredentialsAndGetUserData(user.Email, user.Password) as JsonResult;  // <--- This never returns 12 
            Assert.IsNotNull(result.Data);
            Assert.AreEqual(12, result);
        }

我希望得到的结果是我模拟的数据是12，请有人帮我，我为此苦苦了很长时间...
