Mocking a method to throw an exception (moq), but otherwise act like the mocked object?

Question

I have a Transfer class, simplified it looks like this:

public class Transfer
{
    public virtual IFileConnection source { get; set; }
    publ         


        

Answer 1

This is how I managed to do what I was trying to do:

[Test]
public void TransferHandlesDisconnect()
{
    // ... set up config here
    var methodTester = new Mock(configInfo);
    methodTester.CallBase = true;
    methodTester
        .Setup(m => 
            m.GetFile(
                It.IsAny(), 
                It.IsAny(), 
                It.IsAny()
            ))
        .Throws();

    methodTester.Object.TransferFiles("foo1", "foo2");
    Assert.IsTrue(methodTester.Object.Status == TransferStatus.TransferInterrupted);
}

If there is a problem with this method, I would like to know; the other answers suggest I am doing this wrong, but this was exactly what I was trying to do.
