Make protected inner class public

I have the following class:

class A
{
protected:
    class InnerA {};
};

Now I need to gain access to InnerA class in the tests. Theoretically I could create a test class derived from A and make some parts of A class public. I could do this with fields of course, but not with inner classes.

Is there a way to see the protected InnerA class from outside of A class hierarchy (all classes derived from A)? I would like to be able to write:

Test(MyTest, InnerATest)
{
    TestA::InnerA x;
    x.DoSth();
}
Solution

  • You can inherit and publicize the class, as a matter of fact.

    class A
{
protected:
    class InnerA {};
};

struct expose : A {
    using A::InnerA;
};

int main() {

    expose::InnerA ia;

    return 0;
}

    As you would any other protected member of the base. This is standard C++.
