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