Moq返回一個方法的對象

Question

我有以下的單元測試，我正在使用MOQ來設置從一個類返回的對象。然而，當我嘗試引用mock.Object它引用的接口類型不是我試圖返回

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應ThroughfareNumberIdentifier不IlluSiteInformation類型。

任何幫助，這將不勝感激

感謝

它做什麼你告訴它做的事。通過創建new Mock<ILLUSiteInformation>();，您的意思是「給我一個類型爲ILLUSiteInformation的模擬器」。

當您使用您的設置：

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

你說「當GetThroughfareNumber被調用，並通過了15號作爲一個字符串，返回throughFareIdentifier」。

呼叫throughfareMock.Object.GetThroughfareNumber()而不是使用Mock對象，像這樣

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

確保只使用15號作爲一個字符串（因爲這是你設置什麼了）。如果你想使用任何字符串，請致電

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);
