stub a function with the class I am testing.

[ramyanee]

Hi folks

need help achieving this: I am testing class Myclass with member functions A and B such that A calls B. 

A()

{ 

    ret = B();
}

I need alternate values for ret, I need B to ret something I want. Can this be done? I know how to stub functions from a separate class but i am stuck here.

Both A and B are public.

Hi

One way: Subclass and override...

Make B() virtual.
Make a class that inherits the original class and override B() for test.

You can also do it with the linker. But you need to split B() into a separate file.

If you need to do this, you likely have a design problem.

Cheers, HTH, James
