### Question:
SxpEpProviderProviderInstance implements SxpEpProviderProvider, ClusterSingletonService, AutoCloseable { @Override public void instantiateServiceInstance() { LOG.info("Instantiating {}", this.getClass().getSimpleName()); sxpEpProviderProvider = new SxpEpProviderProviderImpl(dataBroker, endpointService, registry, sgtGeneratorConfig); } SxpEpProviderProviderInstance(DataBroker dataBroker, BaseEndpointService endpointService,
                                         DomainSpecificRegistry registry,
                                         ClusterSingletonServiceProvider clusterSingletonService,
                                         SgtGeneratorConfig sgtGeneratorConfig); void initialize(); @Override void instantiateServiceInstance(); @Override ListenableFuture<Void> closeServiceInstance(); @Override void close(); @Override ServiceGroupIdentifier getIdentifier(); @Override EPToSgtMapper getEPToSgtMapper(); @Override EPPolicyTemplateProviderRegistry getEPPolicyTemplateProviderRegistry();  }### Answer:
@Test public void testInstantiateServiceInstance() throws Exception { instance.instantiateServiceInstance(); verifyNew(SxpEpProviderProviderImpl.class).withArguments(dataBroker, endpointService, domainSpecificRegistry, sgtGeneratorConfig); }
