I think this is more complicated than it needs to be. All you should
need is the vtable_iid field. Then, in the inner loop do something like

if (IsEqualGUID(tests[i].vtable_iid, tests[j].vtable_iid))
    ok(iface1 == iface2, ...);
else
    ok(iface1 != iface2, ...);

I may be missing something though.

If you want to compare two Win32 BOOLs for equality you have to be careful:

BOOL a = 1;
BOOL b = 2;
if (a)
   printf("this is true.\n");
if (b)
   printf("this is also true.\n");
if (a == b)
   printf("oops, this is false.\n");

For something like that you can use
if (!a == !b)
    printf("yay, this is true!\n");

IsEqualGUID(a, b) is defined as !memcmp(a, b, sizeof(GUID)), so
IsEqualGUID() == (ptr1 == ptr2) should be OK though.
