c# - Moq 设置 ServiceLocator

Question

我正在尝试为单元测试设置服务定位器，如下所示:

var mockS = new Mock<IServiceLocator>();
ServiceLocator.SetLocatorProvider(() => mockS.Object);
mockS.Setup(x => x.GetInstance<IObjectFactoryMethod<IAddress>>()).Returns(new Mock<ObjectsFactory>().Object);

var factoryMock = new Mock<IObjectFactoryMethod<IAddress>>(MockBehavior.Strict);
factoryMock.Setup(x => x.Create(null)).Returns(new Mock<IAddress>());

var factory = ServiceLocator.Current.GetInstance<IObjectFactoryMethod<IAddress>>();

// testing - factory returns null
var address = factory.Create(null); // address is null

代码执行良好。工厂在调试期间显示为模拟工厂，但是当调用 Create(null) 时，它返回 null 而不是新的 IAddress 模拟。

尝试这样的事情:

var mockS = new Mock<IServiceLocator>();
ServiceLocator.SetLocatorProvider(() => mockS.Object);

var factoryMock = new Mock<IObjectFactoryMethod<IAddress>>(MockBehavior.Strict);
factoryMock.Setup(x => x.Create(null)).Returns(new Mock<IAddress>().Object);

mockS.Setup(x => x.GetInstance<IObjectFactoryMethod<IAddress>>()).Returns(factoryMock.Object);

var factory = ServiceLocator.Current.GetInstance<IObjectFactoryMethod<IAddress>>();

// testing - factory returns null
var address = factory.Create(null); // address is null
