C＃單元測試錯誤，在運行測試

Question

我使用起訂量的框架工作的一個單元測試項目中，C＃4.0中，當無法加載文件或程序MVC2.0

測試類似於一個在下面。但是，只要我運行這個測試，我得到一個奇怪的錯誤。我已經檢查了所有引用的System.Web.mvc程序集，並且它們都在2.0.0版本中，所以在我看來這些程序不會導致問題。

[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); 
     } 

我期待該方法返回一個URL，在這種情況下應該存儲在名爲'actual'的變量中。但是，每當我運行測試，我收到以下錯誤信息;

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

時被調用，我要測試的功能此錯誤occures，所以只要下面的規則正在被測試擊中發生;

var actual = webshopController.PaymentStepOne(collection); 

連同錯誤信息，我發現了以下堆棧跟蹤

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

請通過找到這個錯誤的原因助陣，並解決它。

Answer 1

我解決了這個問題。我正在測試的函數使用XVal來拋出RulesExceptions。我知道xval並不適用於MVC2，它使用了MVC1中的組件。而且，因爲我正在使用新安裝的機器，所以尚未安裝MVC1。所以我下載了MVC1，安裝完成後我的測試成功了。

有一點還是很奇怪。其他測試中，我的同事和我正在測試RulesExceptions的拋出一直都成功。那麼爲什麼這個測試不是沒有安裝MVC1對我來說仍然是一個大問題。如果有人能告訴我爲什麼我會很高興聽到它。

感謝您的幫助和思考！

Answer 2

您是否從測試項目以及您的生產項目中參考了MVC組件？程序集引用不是以傳遞方式處理的。
