  assertTrue(item + " must not be Object#equals to null", !item.equals(null));
  assertTrue(
    item + " must not be Object#equals to an arbitrary object of another class",
    !item.equals(NotAnInstance.EQUAL_TO_NOTHING));
  assertEquals(item + " must be Object#equals to itself", item, item);
  assertEquals(
    "the Object#hashCode of " + item + " must be consistent",
    item.hashCode(),
    item.hashCode());
 }
