Moq how to correctly mock set only properties

Question

What is the correct way for dealing with interfaces the expose set-only properties with Moq? Previously I've added the other accessor but this has bled into my domain too far with random throw new NotImplementedException() statements throughout.

I just want to do something simple like:

mock.VerifySet(view => view.SetOnlyValue, Times.Never());

But this yields a compile error of The property 'SetOnlyValue' has no getter

Answer 1

public class Xyz
{
    public virtual string AA { set{} }
}
public class VerifySyntax
{
    [Fact]
    public void ThisIsHow()
    {
        var xyz = new Mock<Xyz>();
        xyz.Object.AA = "bb";
        // Throws:
        xyz.VerifySet( s => s.AA = It.IsAny<string>(), Times.Never() );
    }
}
public class SetupSyntax
{
    [Fact]
    public void ThisIsHow()
    {
        var xyz = new Mock<Xyz>();
        xyz.SetupSet( s => s.AA = It.IsAny<string>() ).Throws( new InvalidOperationException(  ) );
        Assert.Throws<InvalidOperationException>( () => xyz.Object.AA = "bb" );
    }
}
