### Question:
SimpleKeyBinding extends SimpleColumnBinding implements KeyBinding { @Override protected void visitFacetChildren(Object facetValue, Predicate<Facet> predicate, PojoVisitor visitor) { } SimpleKeyBinding(Facet facet, String columnName, Converter converter); @Override void describe(Table table, Schema schema); @Override void verifySchema(KeyspaceMetadata keyspaceMetadata, TableMetadata tableMetadata); @Override KeyComponent createClusteringColumnReferenceComponent(Facet referenceFacet, PojoBinding<?> pojoBinding, NamingStrategy namingStrategy); @Override ColumnBinding createReferenceBinding(Facet referenceFacet, PojoBinding<?> pojoBinding, NamingStrategy namingStrategy); @Override void delete(Delete.Where delete); @Override List<Object> elementToKeys(Object element); @Override DataType getElementDataType(); @Override Object getElementValue(Object pojo); @Override List<Object> getKeyParameters(List<Object> keys); @Override void selectWhere(Select.Where select);  }### Answer:
@Test public void testVisitChildren() { binding.visitFacetChildren("foo", facet -> true, visitor); Mockito.verifyNoMoreInteractions(visitor); }
