I may add that the following lambda can be shortened significantly:

mockOrderStorage.Setup(os => os.GetOrder(It.IsAny())).Returns((int id) => {
var order = new Order() { OrderId = id };
return order;
});

mockOrderStorage.Setup(os => os.GetOrder(It.IsAny())).Returns((int id) => new Order { OrderId = id });

(no need to do the var neither the return )

Looks like you read the Martin Fowler article, and failed to understand it. Your test uses a stub, not a mock. According to Fowler, the big difference is in what your testing. With a Stub, your testing state. With a Mock, your testing behavior. You didn’t care if GetOrder was called, you only cared about the result (state) of the call to ShipOrder. This means you used a stub, regardless of whether or not the Moq uses Mock as the type name here.

You seem to equate stubs with hand coded classes and mocks with runtime generated objects. This isn’t accurate, and either can be either hand coded or generated (runtime or compile time).
