### Question:
OrderedProperties { LinkedHashMap<String, String> orderedMap() { return map; }  void load(Reader reader);  }### Answer:
@Test public void testOrderedPropertiesNotLoadedIsEmpty() { OrderedProperties props = new OrderedProperties(); assertThat(props.orderedMap().entrySet().isEmpty(), is(true)); }
@Test public void testOrderedPropertiesUseInsertionOrderedMap() { OrderedProperties props = new OrderedProperties(); assertThat(props.orderedMap(), instanceOf(LinkedHashMap.class)); }
