C test framework proto

// Here begins the framework header

int register_test(const char *name, void (*ptr)());

#define STRINGIFY(s) #s

// NOTE: The trick below, initializing a constant with an expression, doesn't work in C.
// It works in C++ BUT the order of initialization is undefined. It's possible to maintain a
// counter in a macro variable (e.g. Boost preprocessor does this),
// or one could just run the tests in alphabetical order if one is lazy.

#define TEST(name) \
  static void name(); \
  static int name ## _registration = register_test(STRINGIFY(name), &name); \

// Here begins the framework implementation

{
    printf("Adding test %s (%p) to global list.\n", name, ptr);
    /* TODO */

}

// Here ends the framework

    printf("trololoo\n");
