Moq返回一个方法的对象

Question

我有以下的单元测试，我正在使用MOQ来设置从一个类返回的对象。然而，当我尝试引用mock.Object它引用的接口类型不是我试图返回

var throughFareIdentifer = new ThoroughfareNumberIdentifier(); 

var throughfareMock = new Mock<ILLUSiteInformation>(); 
throughfareMock.Setup(x => x.GetThroughfareNumber("15")).Returns(throughFareIdentifer); 


var siteInformation = _lluSiteInformation.GetSiteDetails("", "", "", "", "", "", "", "", throughfareMock.Object); 

throughfareMock.Object应ThroughfareNumberIdentifier不IlluSiteInformation类型。

任何帮助，这将不胜感激

感谢

它做什么你告诉它做的事。通过创建new Mock<ILLUSiteInformation>();，您的意思是“给我一个类型为ILLUSiteInformation的模拟器”。

当您使用您的设置：

throughfareMock.Setup(x => x.GetThroughfareNumber("15")).Returns(throughFareIdentifer); 

你说“当GetThroughfareNumber被调用，并通过了15号作为一个字符串，返回throughFareIdentifier”。

呼叫throughfareMock.Object.GetThroughfareNumber()而不是使用Mock对象，像这样

_lluSiteInformation.GetSiteDetails("", "", "", "", "", "", "", "", throughfareMock.Object.GetThroughfareNumber("15"); 

确保只使用15号作为一个字符串（因为这是你设置什么了）。如果你想使用任何字符串，请致电

throughfareMock.Setup(x => x.GetThroughfareNumber(It.IsAny<string>)).Returns(throughFareIdentifer); 

如果你想使用int

throughfareMock.Setup(x => x.GetThroughfareNumber(It.IsAny<int>)).Returns(throughFareIdentifer);
