Question

For unit testing, I’m using NUnit 2.6 and Moq 4.0. There’s a particular case concerning virtual members where Moq’s proxy objects don’t relay method calls to the actual implementation (probably by design). For instance, if I had a class…

public class MyClass {
    protected virtual void A() {
        /* ... */
    }

    protected virtual void B(...) {
        /* ... */
    }
}

…and I use Moq to override GetSomethingElse‘s A() method in my test fixture…

var mock = new Mock<MyClass>();
mock.Protected().Setup("A").Callback(SomeSortOfCallback);

…using the mock’s A method works splendidly; however, if anything in said method would call not-mocked method B, the method will do nothing and/or return default values, even if an actual implementation exists in MyClass.

Is there a way to work around this? Am I using Moq wrong?

Thanks in advance,
Manny

Set mock.CallBase = true and you should be good to go.
