### Question:
AAIConfigurationResources { public Optional<org.onap.aai.domain.yang.Configuration> getConfiguration(String configurationId) { AAIResourceUri aaiResourceUri = AAIUriFactory.createResourceUri(AAIFluentTypeBuilder.network().configuration(configurationId)); return injectionHelper.getAaiClient().get(org.onap.aai.domain.yang.Configuration.class, aaiResourceUri); }  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 getConfigurationTest() { AAIResourceUri aaiResourceUri = AAIUriFactory.createResourceUri(AAIFluentTypeBuilder.network().configuration("configurationId")); doReturn(Optional.of(new org.onap.aai.domain.yang.Configuration())).when(MOCK_aaiResourcesClient) .get(org.onap.aai.domain.yang.Configuration.class, aaiResourceUri); aaiConfigurationResources.getConfiguration("configurationId"); verify(MOCK_aaiResourcesClient, times(1)).get(org.onap.aai.domain.yang.Configuration.class, aaiResourceUri); }
