使用Moq模拟构造函数? [英] Use Moq to mock Constructor?
本文介绍了使用Moq模拟构造函数?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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.
