Question

我正在尝试创建RESTApi的单元测试但是当我尝试从控制器调用.Get {id}方法时出现错误。

（控制器被嘲笑，因为它是抽象的）

当我到达测试的最后一行时，我收到错误（标题中）。

（我已经尝试过Asserts和.Verify（），但是我没有联系到他们，因为我在到达之前就错了）

我觉得我错过了一些小事，但这又是我第一次和Moq在一起。

    protected CustomActionModelController(IModelProvider<TModel> provider, IModelMapper mapper)
    {
        _mapper = mapper;
        _provider = provider;
        _customActions = new Dictionary<string, Func<string, object, object>>();

        InitializeCustomActions();
    }

    protected abstract void InitializeCustomActions();


    [HttpGet("{id}")]
    [Produces(DefaultContentType)]
    public virtual TDto Get([FromRoute]string Id)
    {
        return ToDto(_provider.Get(Id));
    }



    [TestMethod]
    public void GetWithIdParameterReturnsSingleObject()
    {
        var provider = new Mock<IModelProvider<BaseDomainModel>>();
        var mapper = new Mock<IModelMapper>();
        var services = new Mock<IServiceCollection>();
        var builder = new AutofacBuilder();
        builder.RegisterType<IModelProvider<BaseDomainModel>, FakeDataProvider>().SingletonScope();
        var customMock = new Mock<CustomActionModelController<BaseDomainModel, BaseObjectDto>>(provider.Object, mapper.Object);
        customMock.Setup(x => x.Get(It.IsAny<string>())).Returns((BaseObjectDto s) =>  s = new BaseObjectDto("Test", "test"));
        var actual = customMock.Object.Get("1");
    }

不要设置测试方法。在模拟中使用CallBase

var customMock = new Mock<CustomActionModelController<BaseDomainModel, BaseObjectDto>>(provider.Object, mapper.Object) {
    // Whether the base member virtual implementation 
    // will be called for mocked classes if no setup is matched.
    CallBase = true 
};

var actual = customMock.Object.Get("1");

参考Moq: Quickstart - Customizing Mock Behavior

使用类型为String.String的Moq对象的单元测试RESTapi无法转换为BaseObjectDto
