test_sum is assumedly relatively trivial. So as a lay person I’d expect some sort of obviousness test to apply. Like so much of the stuff in the Google/Oracle lawsuit.

But if you take all the individual tests used to test git as a whole, that seems far more unique. Seems like at that point you’re really having to duplicate the actual git internals, and that seems like it should be covered.

Feel free to extrapolate to the threshold where it's not and at that point apply.

Copyright covers the expression, not the method. So the Rust function:

    fn sum(a: u8, b: u8) {
        a + b
    }

    int sum(int a, int b) 
    {
        return a + b;
    }
