Moq – How to verify that a property value is set via the setter

I would expect the following test to fail:

public interface IObjectWithProperty
{
    int Property { get; set; }
}

[TestMethod]
public void Property_ShouldNotBeCalled()
{
    var mock = new Mock<IObjectWithProperty>();

    mock.Object.Property = 10;

    mock.Verify(x => x.Property, Times.Never());
}

However, this test passes, even though Property is clearly accessed on the line before the Verify.

So it seems that Verify actually means VerifyGet.

How should I verify that a property is never set?

Answer 1

Use the following code instead:

mock.VerifySet(x => x.Property = It.IsAny<int>(), Times.Never());
