Another option is to make those member functions protected and derive a
class for testing purposes that promotes them to public.

  class A {
    int a;
  protected:
    int get_value () { return a; }
  };

  class test_A : public A {
  public:
    using get_value ();
  };

Now your tests can use test_A objects and access its public get_value().
Just keep class test_A out of your program/module and everything should
be fine.

This approach has the benefit that it keeps all the testing stuff out of
your regular code as well.

Hope this helps,
