I don't think that this is a good practice for internal API, I would prefer 
that we do what is necessary now and in the future if anyone wants a more 
generic API then he can either refactor this code or add a new method.

You are not testing the API that you have.

You have a method that's supposed to find NICs with a certain MAC address, but 
what you test is that a "magic" ID is found, not the actual thing that the API 
is supposed to do.

Also it's a bad idea to assume how much of these NICs there will be, unless MAC 
address is unique (but we know it's not).
