You have not shown what A
looks like above, so it's not obvious what's happening, but it looks to me like you're expecting the library to work outside the rules of the language.
Unless A
has a virtual function Add(int, int)
, then the call a->Add(x,y)
is going to call the function in A::Add
, no your MockA.::Add
.
To answer the questions you asked: Static member functions cannot be mocked. Non-virtual functions can be mocked, but its use is limited. If it's not virtual, then obviously virtual dispatch won't happen. But it can be useful if the type is deduced in a template.
(contrived example)
template <typename T>
void test_func_call(T& t)
{
assert(t.func(1) > 0);
}
struct mock
{
MAKE_MOCK1(func, int(int));
};
int main()
{
mock m;
REQUIRE_CALL(m, func(1)).RETURN(3);
test_func(m);
}

yes, the function Add is virtual funciton as following:
class A {
public:
virtual int Add(int a, int b) {
return a + b;
}
};
about the point "Non-virtual functions can be mocked, but its use is limited."
RE: in case that I want to test the logic impl of a member functionA , and functionA called functionB which provided by another class, so I want to mock functionB, so that I can test only the logic impl of funcA.
^_^ If I used in my old project, it's not a good way to modify those 'old code', also it's not permitted, I think.
