Is it good practise to put empty line between logic and asserts in test methods? [closed]

I often see in tests that people leave empty line between some test logic and assertions in tests. Is it good practise? Should I always do it, even if test is very small and consist of 2 lines?

For example:

@Test
public void simple() {
  int a = 2;
  int b = 2; 
  result = sum(a, b);

  assertEquals(result, 4);
}
