### Question:
AAIConfigurationResources { public void disconnectConfigurationToServiceInstance(String configurationId, String serviceInstanceId) { AAIResourceUri configurationURI = AAIUriFactory.createResourceUri(AAIFluentTypeBuilder.network().configuration(configurationId)); AAIResourceUri serviceInstanceURI = AAIUriFactory.createResourceUri(Types.SERVICE_INSTANCE.getFragment(serviceInstanceId)); injectionHelper.getAaiClient().disconnect(configurationURI, serviceInstanceURI); }  void createConfiguration(Configuration configuration); Optional<org.onap.aai.domain.yang.Configuration> getConfiguration(String configurationId); void updateConfiguration(Configuration configuration); void disconnectConfigurationToServiceInstance(String configurationId, String serviceInstanceId); void connectVrfConfigurationToVnrConfiguration(String vrfConfigurationId, String vnrConfigurationId); void connectConfigurationToPnfObject(String pnfId, String configurationId); void connectConfigurationToServiceInstance(String configurationId, String serviceInstanceId); void connectConfigurationToServiceInstance(String configurationId, String serviceInstanceId,
            AAIEdgeLabel aaiLabel); void connectConfigurationToGenericVnf(String configurationId, String genericVnfId); void connectConfigurationToVpnBinding(String configurationId, String vpnId); void connectConfigurationToVfModule(String configurationId, String vnfId, String vfModuleId); void connectConfigurationToVnfc(String configurationId, String vnfcName); void connectConfigurationToL3Network(String configurationId, String networkId); void deleteConfiguration(String configurationId); void deleteConfiguration(Configuration configuration); Optional<org.onap.aai.domain.yang.Configuration> getConfigurationFromRelatedLink(String relatedLink); void updateOrchestrationStatusConfiguration(Configuration configuration,
            OrchestrationStatus orchestrationStatus); void updateConfigurationOrchestrationStatus(Configuration configuration,
            OrchestrationStatus orchestrationStatus);  }### Answer:
@Test public void disconnectConfigurationToServiceInstanceTest() { doNothing().when(MOCK_aaiResourcesClient).disconnect(isA(AAIResourceUri.class), isA(AAIResourceUri.class)); aaiConfigurationResources.disconnectConfigurationToServiceInstance("TEST_CONFIGURATION_ID", "TEST_SERVICE_INSTANCE_ID"); verify(MOCK_aaiResourcesClient, times(1)).disconnect(any(AAIResourceUri.class), any(AAIResourceUri.class)); }
