### Question:
GUIDResponse extends FFDCResponseBase { public String getGUID() { return guid; } GUIDResponse();  GUIDResponse(GUIDResponse   template); String getGUID(); void setGUID(String guid); @Override String toString(); @Override boolean equals(Object objectToCompare); @Override int hashCode();  }### Answer:
@Test public void testNullObject() { GUIDResponse nullObject = new GUIDResponse(); assertTrue(nullObject.getRelatedHTTPCode() == 200); assertTrue(nullObject.getExceptionClassName() == null); assertTrue(nullObject.getExceptionErrorMessage() == null); assertTrue(nullObject.getExceptionSystemAction() == null); assertTrue(nullObject.getExceptionUserAction() == null); assertTrue(nullObject.getExceptionProperties() == null); assertTrue(nullObject.getGUID() == null); nullObject = new GUIDResponse(null); assertTrue(nullObject.getRelatedHTTPCode() == 200); assertTrue(nullObject.getExceptionClassName() == null); assertTrue(nullObject.getExceptionErrorMessage() == null); assertTrue(nullObject.getExceptionSystemAction() == null); assertTrue(nullObject.getExceptionUserAction() == null); assertTrue(nullObject.getExceptionProperties() == null); assertTrue(nullObject.getGUID() == null); }
