我遇到的问题是使用Moq获取所有的Mocking设置.由于HttpContextBase没有被正确地模拟,所以我不断得到空的异常.我认为.

有人能帮我弄清楚我没有做什么相关的事情吗？

以下是单元测试的示例我正在尝试写入不起作用：

[TestMethod()]
public void BindModelTest()
{
    JsonDictionaryModelBinder target = new JsonDictionaryModelBinder();

    NameValueCollection nameValueCollection = new NameValueCollection() {
        {"First","1"},{"Second","2"},{"Name","Chris"},{"jsonValues","{id: 200,name: 'Chris'}"}
    };

    HttpContextBase httpContext = MockHelper.FakeHttpContext(HttpVerbs.Post,nameValueCollection);

    ControllerContext controllerContext =
        new ControllerContext(new RequestContext(httpContext,new RouteData()),new Mock<Controller>().Object);


    Predicate<string> predicate = propertyName => (propertyName == "jsonValues");
    ModelBindingContext bindingContext = new ModelBindingContext()
    {
        Model = null,ModelType = typeof(JsonDictionary),ModelState = new ModelStateDictionary(),PropertyFilter = predicate,ValueProvider = new Dictionary<string,ValueProviderResult>() { { "foo",null } }
    };

    //object expected = null; // TODO: Initialize to an appropriate value
    var actual = target.BindModel(controllerContext,bindingContext) as JsonDictionary;

    Assert.IsNotNull(actual);

    Assert.AreEqual("Chris",actual["name"]);
    //Assert.AreEqual(expected,actual);
    Assert.Inconclusive("Verify the correctness of this test method.");
}

这是上面使用的“FakeHttpContext”方法：

public static class MockHelper
{
    public static HttpContextBase FakeHttpContext(HttpVerbs verbs,NameValueCollection nameValueCollection)
    {
        var httpContext = new Mock<HttpContextBase>();

        var request = new Mock<HttpRequestBase>();
        request.Setup(c => c.Form).Returns(nameValueCollection);
        request.Setup(c => c.QueryString).Returns(nameValueCollection);

        var response = new Mock<HttpResponseBase>();
        var session = new Mock<HttpSessionStateBase>();
        var server = new Mock<HttpServerUtilityBase>();
        httpContext.Setup(c => c.Request).Returns(request.Object);

        var u = verbs.ToString().ToUpper();
        httpContext.Setup(c => c.Request.RequestType).Returns(
            verbs.ToString().ToUpper()
        );

        httpContext.Setup(c => c.Response).Returns(response.Object);
        httpContext.Setup(c => c.Server).Returns(server.Object);
        httpContext.Setup(c => c.User.Identity.Name).Returns("testclient");
        return httpContext.Object;
    }
}
