Now with this newly created stub, the test case made for function A has broken due to the original function no longer being called, despite not registering for the stub callback. Can someone explain why it is…

To resolve these I generated auto stubs and rebuilt my project again. But the undefined reference errors are not going away. How do I resolve this? Thank you
