最小起订量-如何进入真正的方法？

hyprsleepy 发表于 Dev

昏昏欲睡

我想使用测试数据作为输入，进入真正的方法。

调用GetSurveyList时，它不会注意我给它的日期。它总是返回我手动添加到模拟模型中的所有三个项目。它应该检查日期，并且仅返回日期等于或大于输入日期的那些项目。

如果我介入，那么我只会深入到界面。调用的下一步应该转到实现该接口的代码，而没有。这是Moq的标准行为吗？我以为它可以让您介入？

这是我的代码：

[TestMethod]
public void TestHasListOfSurveys()
{
    var mockRepository = new Mock<ISurveyListRepository>();
    var mockModel = new List<SurveyList>();
    mockModel.Add(new SurveyList { SurveyID = 1, SurveyName = "test1", DeliveryDate = DateTime.Parse("1/1/2014") });
    mockModel.Add(new SurveyList { SurveyID = 2, SurveyName = "test2", DeliveryDate = DateTime.Parse("6/1/2014") });
    mockModel.Add(new SurveyList { SurveyID = 3, SurveyName = "test3", DeliveryDate = DateTime.Parse("12/1/2014") });

    string testDate = DateTime.Today.ToShortDateString();

    mockRepository.Setup(x => x.GetSurveyList(testDate)).Returns(mockModel);

    var testClass = new SurveyListModel(mockRepository.Object);
    var testModel = testClass.GetSurveyList(testDate);

    mockRepository.VerifyAll();

    Assert.IsTrue(testModel.Count > 0);
}

从资源库中获取GetSurveyList：

公共类SurveyListRepository：ISurveyListRepository

public List<SurveyList> GetSurveyList(String deliveryDateAfterInput)
{
    List<SurveyList> SurveyLists = new List<SurveyList>();
    string error = string.Empty;

    using (OrderingEntities db = DierbergsAppLib.Entities.EntityFactory.GetInstance<OrderingEntities>(
               new DierbergsAppLib.Entities.EntityFactory.EntityFactoryOptions()
               {
                   EntityNameInConfigFile = "OrderingEntities",
                   ConnectionStringCacheManager = new DierbergsAppLib.Entities.WebCacheConnectionStringManager()
               },
               out error))
    {
        DateTime deliveryDateFilter = Convert.ToDateTime(deliveryDateAfterInput);

        var SurveyList = db.uspOrderSurveyListAllStoresGet(deliveryDateFilter);

        foreach (uspOrderSurveyListAllStoresGet_Result viewsurvey in SurveyList)
        {
           // SurveyLists.Add( )
        }
    }

    List<SurveyList> all = SurveyLists.OrderBy(x => x.SurveyDueDate).ToList();
    return all;
}

来自模型的GetSurveyList：

公共类SurveyListModel

public List<SurveyList> GetSurveyList(String deliveryDateAfterInput)
{
    return _repository.GetSurveyList(deliveryDateAfterInput);
}

测试是您代码的规范。让我们考虑一下SurveyListModel您要通过此测试指定哪种行为方案。在这种情况下，逻辑非常简单：

SurveyListModel应该从存储库返回指定日期的调查

因此，如果您停下来思考，那就不应该验证返回的调查的日期。SurveyListModel职责不涉及以任何方式修改存储库响应。它应该执行以下操作-将date参数传递到一种特定的存储库方法，然后将存储库响应返回给调用方。没有其他的。这就是您应该验证的内容。

var repositoryMock = new Mock<ISurveyListRepository>();
string date = DateTime.Today.ToShortDateString();
repositoryMock.Setup(r => r.GetSurveyList(date)).Returns(CreateTestSurveys());
var model = new SurveyListModel(repositoryMock.Object);

var surveys = model.GetSurveyList(date);

repositoryMock.VerifyAll();
CollectionAssert.AreEqual(CreateTestSurveys(), surveys);

该测试验证
