### Question:
MsoVnfAdapterAsyncImpl implements MsoVnfAdapterAsync { @Override public void healthCheckA() { logger.debug("Health check call in VNF Adapter"); }  @Override void healthCheckA(); @Override void createVnfA(String cloudSiteId, String cloudOwner, String tenantId, String vnfType, String vnfVersion,
            String vnfName, String requestType, String volumeGroupHeatStackId, Map<String, Object> inputs,
            Boolean failIfExists, Boolean backout, Boolean enableBridge, String messageId, MsoRequest msoRequest,
            String notificationUrl); @Override void deleteVnfA(String cloudSiteId, String cloudOwner, String tenantId, String vnfName, String messageId,
            MsoRequest msoRequest, String notificationUrl); String getEncryptedProperty(String key, String defaultValue, String encryptionKey);  }### Answer:
@Test public void healthCheckVNFTest() { instance.healthCheckA(); }
