### Question:
KPITimingDataBindingFactory implements DataBindingFactory { @Override public UnMarshaller getUnMarshaller() { return unMarshaller; } KPITimingDataBindingFactory(KPIMonitor monitor, DataBindingFactory factory,
                    String formatType); @Override Marshaller getMarshaller(); @Override FaultMarshaller getFaultMarshaller(); @Override UnMarshaller getUnMarshaller(); @Override FaultUnMarshaller getFaultUnMarshaller();  }### Answer:
@Test public void testGetUnmarshaller() { UnMarshaller marshaller = factory.getUnMarshaller(); marshaller.unmarshall(null,(Class)null,null, false); assertSame(marshaller, factory.getUnMarshaller()); expectUnMarshall(); }
