模拟知识库返回具有空属性的对象

Question

下面是我的一个单元测试类（简化为基础知识）的示例。在控制器中，当调用Index（）操作方法时，对GetByID（1234）的调用总是会生成一个Ticket对象的新实例。该对象存在，但它的所有属性都是null，即使我已将它们设置在我的假对象中。任何想法为什么？

我正在使用Moq。

单元测试

[TestClass] 
    public class TicketControllerTests : ControllerTestBase 
    { 
     protected Mock<ITicketRepository> MockTicketRepository = new Mock<ITicketRepository>(); 

     [TestMethod] 
     public void IndexActionModelIsTypeOfTicketModel() 
     { 
      //ARRANGE 
      Mock<HttpContextBase> context = FakeHttpContext(); 
      context.Setup(ctx => ctx.Session[SessionKeys.TokenData.ToString()]).Returns(Constants.TOKENDATA_SUBMITTER); 

      MockTicketRepository.Setup(x => x.GetById(It.IsAny<int>())).Returns(Constants.CLIENT_TICKET); 

      //ACT 
      var result = GetController(context.Object).Index(Constants.TICKET_ID); 
      var model = ((ViewResult)result).Model; 

      //ASSERT 
      Assert.IsInstanceOfType(model, typeof(TicketModel), "ViewModel should have been an instance of TicketModel."); 
     } 

     private TicketController GetController(HttpContextBase context) 
     { 
      var controller = new TicketController(MockTicketRepository.Object); 
      controller.ControllerContext = GetControllerContext(context, controller); 
      return controller; 
     } 
    } 

Constants.CLIENT_TICKET

public static Ticket CLIENT_TICKET 
     { 
      get 
      { 
       var ticket = new Ticket 
       { 
        CategoryID = 1, 
        CreatedByUserId = 4 
       }; 

       ticket.Clients.Add(new Client { ShortName = "Test Client 1"}); 
       ticket.Clients.Add(new Client { ShortName = "Test Client 2" }); 

       ticket.User = new User {FirstName = "First", LastName = "Last"}; 

       return ticket; 
      } 
     } 

控制器

private readonly ITicketRepository _ticketRepository; 

public TicketController(ITicketRepository ticketRepository) 
{ 
    _ticketRepository = ticketRepository; 
} 

public ActionResult Index(int id) 
{ 
    var ticket = _ticketRepository.GetById(id); 

    // etc... 
}

你能显示的C测试中的ontroller代码？这可能与您如何设置模拟的上下文有关，但很难说没有看到控制器代码。

此外，如果添加MockBehavior.Strict当您创建模拟，它会弹了出来，如果调用没有相应的期望：

protected Mock<ITicketRepository> MockTicketRepository = new Mock<ITicketRepository>(MockBehavior.Strict); 

UPDATE 我试图剥夺一切恢复使该测试尽可能简单，以尝试隔离问题。以下是我想到的：

[TestClass] 
public class TicketControllerTests : ControllerTestBase 
{ 
    protected Mock<ITicketRepository> MockTicketRepository; 

    [TestMethod] 
    public void IndexActionModelIsTypeOfTicketModel() 
    { 
     //ARRANGE 
     MockTicketRepository = new Mock<ITicketRepository>(MockBehavior.Strict); 
     MockTicketRepository.Setup(x => x.GetById(Constants.TICKET_ID)).Returns(Constants.CLIENT_TICKET); 
     var controller = new TicketController(MockTicketRepository.Object); 

     //ACT - try to keep ACT as lean as possible, ideally just the method call you're testing 
     var result = controller.Index(Constants.TICKET_ID); 

     //ASSERT 
     var model = ((ViewResult)result).ViewData.Model; 
     Assert.That(model, Is.InstanceOfType<TicketModel>(), "ViewModel should have been an instance of TicketModel.") 
    } 
}
