in C/C++test

Hello Community,

I am a first time user of Parasoft's dynamic stubs. I am evaluating this feature as an alternate to using Google mock.

Can stubs be created for functions in the same class (C++) or same the same file(C)?

    Yes, C++test can create stubs for functions from the same file / class.
    In general, stub can be created if the function is used / called somewhere in the tested code (with some exceptions).

    C:

    void zoo(); // can be stubbed - used in goo()

void foo() // cannot be stubbed - never called
{
}

void goo() // can be stubbed - used in bar()
{
  zoo(); // stubZoo() will be used here
}

void bar() // cannot be stubbed - never called
{
  goo(); // stubGoo() will be used here (if exists)
}

    C++:

    // .h
class Stubs {
public:
  void zoo(); // can be stubbed - used in Stubs::goo()
  void foo(); // cannot be stubbed - never called
  void goo(); // can be stubbed - used in Stubs::bar()
  void bar(); // cannot be stubbed - never called
};

// .cpp
void Stubs::foo() // cannot be stubbed - never called
{
}

void Stubs::goo() // can be stubbed - used in Stubs::bar()
{
  this->zoo(); // stubZoo() will be used here
}

void Stubs::bar() // cannot be stubbed - never called
{
  this->goo(); // stubGoo() will be used here (if exists)
}
