How can I change a static method behavior in C++?

Is there a way to modify the behavior of a static method to return different parameters?

I am using Gmock for mocking but in this case I am not able to change my code and the methods must stay static

for example

class MyClass
{
public:
    static int GetSomething()
    {
        return -1; 
    }
};

I need the method to return positive number

Disclaimer - I work at Typemock the unit-testing company. You can easily change the behavior of a method with our API, for example:

WHEN_CALLED(MyClass::GetSomething()).Return(15);

In that way, in all of your tests, GetSomehting will return 15. It will work on Non Static methods too.

In that case your options are limited, but if it's just for a mock, then just make the method return a static variable instead of a hard coded value. 

class MyClass
{
  static int somethingValue;
public:
  static int GetSomething()
  {
    return somethingValue; 
  }
  static void SetSomething(int value)
  {
    somethingValue = value; 
  }
};
int MyClass::somethingValue = -1;
