### Question:
PointerItem extends BaseItem { public static Map<String, Condition> filterFor() { Map<String, Condition> result = new HashMap<>(1); result.put( sortKeyName(), new Condition() .withAttributeValueList(ATTR_TARGET) .withComparisonOperator(ComparisonOperator.EQ)); return result; } protected  PointerItem(UuidKey pointerTarget, Map<String, AttributeValue> context); static Map<String, Condition> filterFor(); static PointerItem generate(); static PointerItem generate(Map<String, String> context); static PointerItem fromKeyAndContext(String key, Map<String, String> context); Map<String, String> getContext(); @Override Map<String, AttributeValue> toItem(); static Map<String, AttributeValue> atKey(String key); static Map<String, AttributeValue> atKey(AttributeValue key); static PointerItem fromItem(Map<String, AttributeValue> item); Set<ContextItem> contextItems();  }### Answer:
@Test void testFilterFor() { Map<String, Condition> filter = PointerItem.filterFor(); Condition filterCondition = filter.get(PointerItem.sortKeyName()); assertNotNull(filterCondition); assertTrue(filterCondition.toString().contains(PointerItem.TARGET)); }
