Question

我有以下单元测试，我使用MOQ设置从类返回的对象。但是，当我尝试引用mock.Object时，它引用的是接口类型而不是我尝试返回的类型

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应该是ThroughfareNumberIdentifier而不是IlluSiteInformation。

对此有任何帮助将不胜感激

感谢

它正在做你告诉它要做的事情。通过创建new Mock<ILLUSiteInformation>();，你会说“给我一个类型为ILLUSiteInformation的模拟”。

使用设置时：

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

您说“当GetThroughfareNumber被调用，并将数字15作为字符串传递时，返回throughFareIdentifier”。

调用throughfareMock.Object.GetThroughfareNumber()而不是像使用Mock对象那样

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

确保您只使用数字15作为字符串（因为这是您设置的）。如果要使用任何字符串，请调用

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);

Moq从方法返回一个对象
