使用Moq模拟构造函数？ [英] Use Moq to mock Constructor?

问题描述

我有这样一组构造函数：

  public BusinessObjectContext（）：
 
 
 this（CloudStorageAccount.FromConfigurationSetting（DataConnectionString）。TableEndpoint.ToString（），
 CloudStorageAccount.FromConfigurationSetting（DataConnectionString）。Credentials）{} 
 
 public BusinessObjectContext（string dataConnectionString） ：
 this（CloudStorageAccount.Parse（dataConnectionString）.TableEndpoint.ToString（），
 CloudStorageAccount.Parse（dataConnectionString）.Credentials）{} 
 
 public BusinessObjectContext（String baseAddress，StorageCredentials然而，当测试/ Mocking时，我需要的对象没有，但是我不需要这个对象。任何连接字符串参数。 
解决方案
这是否可以在Moq中执行？
 
 
 
听起来好像你有代码气味 -  构造函数正在做太多的工作。本文包括一组针对此类场景的修订。基本上，答案是仅在构造函数中执行赋值，而不是执行业务逻辑。 
 
I have such a set of Constructors:
public BusinessObjectContext() :


this(CloudStorageAccount.FromConfigurationSetting("DataConnectionString").TableEndpoint.ToString(),
             CloudStorageAccount.FromConfigurationSetting("DataConnectionString").Credentials) {}

   public BusinessObjectContext(string dataConnectionString) :
        this(CloudStorageAccount.Parse(dataConnectionString).TableEndpoint.ToString(),
             CloudStorageAccount.Parse(dataConnectionString).Credentials) { }

   public BusinessObjectContext(String baseAddress, StorageCredentials credentials) : base(baseAddress, credentials) { } 
However when testing / Mocking I need the object without any of the connection string parameters. How can I do this - preferrably in Moq?

Is this possible at all?
解决方案
It sounds as if you have a code smell - the constructor is doing too much work. The article includes  a set of fixes for such scenarios. Basically the answer is to only perform assignment in constructors, not execute business logic.
