Question

我试图模拟一个应该返回UserHostAddress的API控制器方法的HttpContextWrapper。我无法控制实施。我只应该对我给出的代码进行单元测试。

我已经在StackOverflow上已经有了一些例子，虽然我已经接近实现我的需求，但我无法超越这个例外：

Moq.MockException：HttpContextBase.ApplicationInstance调用因模拟行为Strict而失败。模拟上的所有调用都必须有相应的设置。

以下是我的单元测试方法：

    private static HttpRequestMessage CreateRequest(string url, string mthv, HttpMethod method)
    {
        var request = new HttpRequestMessage();

        var baseRequest = new Mock<HttpRequestBase>(MockBehavior.Strict);
        var baseContext = new Mock<HttpContextBase>(MockBehavior.Strict);

        baseRequest.Setup(br => br.UserHostAddress).Returns("127.0.0.1");
        baseContext.Setup(bc => bc.Request).Returns(baseRequest.Object);

        var baseContextWrapper = new Mock<HttpContextWrapper>(baseContext.Object.ApplicationInstance.Context);

        request.RequestUri = new Uri(url);
        request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue(mthv));
        request.Properties.Add("MS_HttpContext", baseContextWrapper.Object);
        request.Method = method;

        return request;
    }

    [Test]
    public void IsClientIpAddressReturned()
    {
        // Assign
        var request = CreateRequest("http://myserver/api/CustomerController", "application/json", HttpMethod.Get);

        var apiCachedController = new ApiCachedController();

        // Act
        RequestManager.RegisterRequestWithThread();

        var address = apiCachedController.GetClientIpAddress(request);

        // Assert
        Assert.AreEqual(address, "127.0.0.1");
    }

在方法CreateRequest中，您引用了ApplicationInstance.Context模拟中的baseContext。但是，您没有此属性的安装程序：

var baseContextWrapper = new Mock(baseContext.Object.ApplicationInstance.Context);

在Mock baseContext上设置Context

Moq：HttpContextBase.ApplicationInstance调用失败，模拟行为严格
