運行單元測試時出現服務錯誤

Question

我最初寫了一個單元測試失敗，現在我已經解決了這個問題，但是當我嘗試再次運行單元測試時，出現此錯誤

System.InvalidOperationException：在ServiceModel客戶端配置部分中找不到引用合同'InventoryManager.Services.IUserService'的默認終結點元素。 這可能是因為找不到您的應用程序的配置文件，或者是因為在客戶端元素中找不到與該協定匹配的端點元素。

我不知道為什么會這樣，因為我在單元測試App.Config中使用的配置與我在服務庫App.Config中使用的配置相同，並且合同名稱相同。

Answer 1

單元測試的應用程序配置文件應包含<clients>部分，而不是<services>部分。

從單元測試的配置文件中刪除<services>部分，並將其替換為以下內容：

<client>
  <endpoint address="http://localhost:3637/Service.svc" 
            binding="basicHttpBinding" 
            contract="InventoryManager.Services.IUserService">
</client>

<services>部分用於定義服務應用程序的服務，而<client>部分用於定義客戶端將連接到的服務。
