### Question:
NetworkHandler extends BaseHandler implements INeutronNetworkAware { @Override public int canUpdateNetwork(NeutronNetwork delta, NeutronNetwork original) { return HttpURLConnection.HTTP_OK; }  @Override int canCreateNetwork(NeutronNetwork network); @Override void neutronNetworkCreated(NeutronNetwork network); @Override int canUpdateNetwork(NeutronNetwork delta,
                                NeutronNetwork original); @Override void neutronNetworkUpdated(NeutronNetwork network); @Override int canDeleteNetwork(NeutronNetwork network); @Override void neutronNetworkDeleted(NeutronNetwork network);  }### Answer:
@Test public void testCanUpdateNetwork() { NeutronNetwork delta = new NeutronNetwork(); NeutronNetwork original = new NeutronNetwork(); assertEquals(HttpURLConnection.HTTP_OK, testNetworkHandler.canUpdateNetwork(delta, original)); }
