Question

我正在使用MOQ框架，C＃4.0，MVC2.0进行项目中的单元测试

测试类似于下面的测试。但是一旦我运行这个测试，我就会收到一个奇怪的错误。我已经检查了所有引用的System.Web.mvc程序集以及版本2.0.0的所有内容，所以在我看来那些不会导致问题。

[TestMethod]
        public void PaymentStepOne_Should_Return_RedirectUrl_Because_CustomerId_In_Session_Is_Null()
        {
            var _mockFrontendWebshopController2 = new Mock<FrontendWebshopController>
            (                                                                             
               _mockCartItemService.Object, _mockCartService.Object,                                                                                                         
               _mockOrderService.Object, _mockCustomerService.Object,                                                                               
               _mockVariantService.Object, _mockShippingCostService.Object,                                                                              
               _mockNodeService.Object, _mockPageSettingService.Object,
               _mockUserProfileService.Object) { CallBase = true };   

            var config = ConfigurationManagerHelper.GetConfigurationManager(new DefaultSettings());
            _mockFrontendWebshopController2.Setup(x => x.GetConfigurationManager()).Returns(config);

            var webshopController = _mockFrontendWebshopController2.Object;


            webshopController.SetFakeControllerContext();
            webshopController.Response.Redirect("http://www.google.nl");

            var idToUse = Guid.NewGuid();
            var collection = new FormCollection { { "Id", idToUse.ToString() }, { "Amount_" + idToUse, "99" } };
            var actual = (RedirectResult)webshopController.PaymentStepOne(collection);

            Assert.AreEqual("http://www.google.nl", actual.Url);
        }

我希望该方法在此场景中返回一个URL，该URL应该存储在名为“actual”的变量中。但每当我运行测试时，我收到以下错误消息;

Test method Plugin.Webshop.Tests.FrontendWebshopControllerTest.PaymentStepOne_Should_Return_RedirectUrl_Because_CustomerId_In_Session_Is_Null threw exception:

当我要调用我要测试的函数时会发生此错误，因此只要测试命中以下规则就会发生错误;

var actual = webshopController.PaymentStepOne(collection);

与错误消息一起，我得到以下Stack Trace

Plugin.Webshop.Controllers.FrontendWebshopController.PaymentStepOne(FormCollection collection)

请通过查找此错误的原因并解决它来帮助解决。

Answer 1

您是否从 test 项目以及生产项目中引用了MVC程序集？装配参考不是可传递的。

Answer 2

我解决了这个问题。我正在测试的函数是使用XVal抛出RulesExceptions。我知道xval还不能用于MVC2，它使用MVC1中的组件。由于我正在安装新安装的机器，因此还没有安装MVC1。所以我下载了MVC1，安装完成后我的测试成功了。

有一件事仍然很奇怪。我和我的同事测试抛出RulesExceptions的其他测试确实一直成功。那么为什么这个测试没有安装MVC1对我来说仍然是个大问题。如果有人能告诉我为什么我会乐意听到它。

感谢您的帮助和思考！
