Without adding to it, that's bad advice. Consider writing the

What method do you (or others) recommend to unit-test private
functions (in C++) or file-scope (static) functions without
littering the actual code with stuff needed only for testing?

I'm not sure I understand. I test that a component meets its
external requirements specification. Private functions aren't
part of that.

Testing only the public (or global scope) interface does not
really solve the complexity problem, or does it?

What complexity problem? What problem are you trying to solve
by testing private functions?
