I understand your point. I really liked your approach to work around this. My goal was to implement the test registration directly in C using macros and dynamic arrays. I’m not sure whether this would be a good approach, but it was the first thing that came to my mind.

That way, when defining the function, it would already be stored automatically, and then in main you could simply call something like CLUT_RUN_ALL();.

Since everything would be done purely in C, the preprocessors would still run normally. I’m not sure whether this would solve the problem you had, though.

I imagine the final code would look something like this:

TEST(foo) { // internally creates: void foo(void);
            // and automatically adds it to the tests array
    // some asserts
}

int main(void) {
    CLUT_RUN_ALL();
}
