Can gmock create mock functions for Global functions?

[sarbojit]

Hi,
I was looking into cook book but did not find a way to mock global
functions(c type functions). There they have advised to wrap it into a
class and then use but I was looking for some better solution.

Please let me know if it is possible.

I believe google must have thought about it.

 

One more requirement I am having like,

I am having list of function pointers which I wanted to assigne mock functions generated but gmock, is it possible? Currently I am getting compilation error. not sure if I am trying it in a correct way. e.g.

 

Init_func()

{

.......

MOCK_METHOD2(func,int(int a, char c, float f));

 

int (*foo)(int, char, float);

 

foo = func;

........

}

 

Please let me know the correct way if it is not a correct way.

Googlemock does not support mocking free/global functions:

You can follow the steps in this blog post to change your code to be mockable:

However, if you do not wish to hide access to the function through an interface, you might consider taking a look at my fake function framework.  It works perfectly well alongside googletest and googlemock:
