c# - 模拟对象仍在拨打服务电话

因此，我正在为MVC4应用程序编写测试，并且正在专门测试Controller Action 。正如我在标题中提到的那样，测试仍然会命中服务(WCF)，而不是返回测试数据。我有这个 Controller :

public class FormController : Controller
{
    public SurveyServiceClient Service { get; set; }
    public SurveyDao Dao { get; set; }

    public FormController(SurveyServiceClient service = null, SurveyDao dao = null)
    {
        this.Service = service ?? new SurveyServiceClient();
        this.Dao = dao ?? new SurveyDao(Service);
    }

    //
    // GET: /Form/

    public ActionResult Index()
    {
        var formsList = new List<FormDataTransformContainer>();
        Dao.GetForms().ForEach(form => formsList.Add(form.ToContainer()));

        var model = new IndexViewModel(){forms = formsList};
        return View("Index", model);
    }

它使用此DAO对象:

public class SurveyDao
{
    private readonly SurveyServiceClient _service;
    private readonly string _authKey;

    public SurveyDao(SurveyServiceClient serviceClient)
    {
        _service = serviceClient;
    }

    ....

    public FormContract[] GetForms()
    {
        var forms = _service.RetrieveAllForms();
        return forms;
    }

这是我使用JustMock进行的测试，GetForms()上的模拟在助手类中返回了一些测试数据:

[TestClass]
public class FormControllerTest
{
    private SurveyDao mockDao;
    private SurveyServiceClient mockClient;

    public FormControllerTest()
    {
        mockClient = Mock.Create<SurveyServiceClient>();
        mockDao = Mock.Create<SurveyDao>(mockClient);
    }

    [TestMethod]
    public void TestIndexAction()
    {
        //Arrange
        var controller = new FormController(mockClient, mockDao);
        Mock.Arrange(() => mockDao.GetForms()).Returns(TestHelpers.FormContractArrayHelper);

        //Act
        var result = controller.Index() as ViewResult;

        //Assert
        Assert.IsInstanceOfType(result.Model, typeof(IndexViewModel));
    }
}

我的问题是，当我运行测试时，该服务仍在被调用。我已经使用Fiddler验证了这一点，还调试了测试并检查了以我们服务的测试数据填充的“结果”的值。

编辑:

我已经将测试构造函数更改为[TestInitialize]函数，因此Test现在看起来像这样:

[TestClass]
public class FormControllerTest
{
    private SurveyDao mockDao;
    private SurveyServiceClient mockClient;

    [TestInitialize]
    public void Initialize()
    {
        mockClient = Mock.Create<SurveyServiceClient>();
        mockDao = Mock.Create<SurveyDao>(Behavior.Strict);
    }

    [TestMethod]
    public void TestIndexAction()
    {
        //Arrange
        var controller = new FormController(mockClient, mockDao);
        Mock.Arrange(() => mockDao.GetForms()).Returns(TestHelpers.FormContractArrayHelper);

        //Act
        var result = controller.Index() as ViewResult;

        //Assert
        Assert.IsInstanceOfType(result.Model, typeof(IndexViewModel));
    }
}

最佳答案

请验证您为JustMock使用了正确的程序集。有几种不同的控件(VisualBasic，Silverlight，JustMock)。 JustMock是您应该包含在项目中的一种。

如果未包含正确的代码，则会导致您正在描述的行为(方法未正确说明)。
