func Add(x, y int) int {
	return 3
}

// Why does this test pass given the implementation of Add?
func TestAdd(t *testing.T)  {
	cases := []struct{
		X, Y int
		Want int
	} {

	}

			t.Parallel()
			got := Add(test.X, test.Y)
			if got != test.Want{
				t.Errorf("got %d, wanted %d", got, test.Want)
