### Question:
SxpIseAdapterProviderInstance implements ClusterSingletonService, AutoCloseable { @Override public void instantiateServiceInstance() { LOG.info("Instantiating {}", this.getClass().getSimpleName()); iseAdapterProvider = new GbpIseAdapterProvider(dataBroker, bindingAwareBroker, sxpEpProvider); } SxpIseAdapterProviderInstance(final DataBroker dataBroker,
                                         final BindingAwareBroker bindingAwareBroker,
                                         final ClusterSingletonServiceProvider clusterSingletonService,
                                         final SxpEpProviderProvider sxpEpProvider); void initialize(); @Override void instantiateServiceInstance(); @Override ListenableFuture<Void> closeServiceInstance(); @Override void close(); @Override ServiceGroupIdentifier getIdentifier();  }### Answer:
@Test public void testInstantiateServiceInstance() throws Exception { instance.instantiateServiceInstance(); verifyNew(GbpIseAdapterProvider.class).withArguments(dataBroker, bindingAwareBroker, sxpEpProvider); }
