### Question:
AssetExternalIdentifiers extends AssetPropertyIteratorBase implements Iterator<AssetExternalIdentifier> { @Override public String toString() { return "AssetExternalIdentifiers{" + "pagingIterator=" + pagingIterator + '}'; } AssetExternalIdentifiers(AssetDescriptor              parentAsset,
                                    int                          totalElementCount,
                                    int                          maxCacheSize);  AssetExternalIdentifiers(AssetDescriptor   parentAsset, AssetExternalIdentifiers template); @Override boolean hasNext(); @Override AssetExternalIdentifier next(); @Override void remove(); @Override String toString();  }### Answer:
@Test public void testToString() { assertTrue(getPropertyIterator(10, 100).toString().contains("AssetExternalIdentifiers")); }
