Question

我有以下测试代码。

var test = "Test";

var command = new MyCommand { V = test };

var mock = new Mock<IRepository>(); // IRepository has the method of Save()
var p = new P(test);
mock.Setup(x => x.Save(p)).Verifiable();

var sut = new C(mock.Object);
var result = await sut.M(command);

mock.Verify();

测试应通过。但是，它失败并显示错误，

  Message: 
    Moq.MockException : Mock:
    This mock failed verification due to the following:

       IRepository x => x.Save(P):
       This setup was not matched.
  Stack Trace: 
    Mock.Verify()

sut.M()将字符串X转换为类型为P的类型P(X)。

在我看来，您想验证模拟对象中的Save方法是使用特定值而不是类型进行调用的。

我尝试了以下类似方法，并认为它应该可以工作。我已经修改了您的示例。

var test = "Test";

var command = new MyCommand { V = test };

var mock = new Mock<IRepository>(); 
IRepository has the method of Save()
var p = new P(test);
mock.Setup(x => x.Save(It.IsAny<P>());

var sut = new C(mock.Object);
var result = await sut.M(command);

mock.Verify(x => x.Save(It.Is<P>(v => v.Value.Equals(p.Value))), Times.AtLeastOnce);

这将测试特定属性的值是否相等。

我用以下测试对此进行了测试：

var test = "Test";

var mock = new Mock<ITestRepository>(); // ITestRepository has the method of Save()
var p = new P(test);
mock.Setup(x => x.Save(It.IsAny<P>()));

mock.Object.Save(new P(test));

mock.Verify(x => x.Save(It.Is<P>(v => v.Value.Equals(p.Value))), Times.AtLeastOnce);

Mock.Verify（）失败-此设置不匹配？
