Return 来自模拟方法的模拟

Question

我不确定该怎么做。

鉴于我有

public interface IFactory<T> where T : new()
{
    IWrapper<T> GetT(string s);
}

public interface IWrapper<out T> where T : new()
{
    void Execute(Action<T> action);
}

当我这样做时

public class MoqTest
{
    public void test()
    {
        Mock<IWrapper<basicClass>> wrapperMock = new Mock<IWrapper<basicClass>>();
        Mock<IFactory<basicClass>> factoryMock = new Mock<IFactory<basicClass>>()
            .Setup(p => p.GetT(It.IsAny<string>()))
            .Returns(wrapperMock.Object);
    }
}

我明白了

Cannot implicitly convert type Moq.Language.Flow.IReturnsResult<TestNamespace.IFactory<TestNamespace.basicClass>> to Moq.Mock<TestNamespace.IFactory<TestNamespace.basicClass>>. An explicit conversion exists (are you missing a cast?)

请注意，这些只是模拟的示例对象。

它似乎不认为 return 类型是等价的。一个是 IReturnResult，另一个是 Moq.Mock

您的问题基本上是您将调用 Returns 方法的结果分配给 factoryMock 变量。

您想先创建模拟并将其分配给 factoryMock 变量，然后像这样设置模拟：

Mock<IWrapper<basicClass>> wrapperMock = new Mock<IWrapper<basicClass>>();
Mock<IFactory<basicClass>> factoryMock = new Mock<IFactory<basicClass>>();

factoryMock
    .Setup(p => p.GetT(It.IsAny<string>()))
    .Returns(wrapperMock.Object);
