### Question:
MsoNeutronUtils extends MsoCommonUtils { public boolean deleteNetwork(String networkId, String tenantId, String cloudSiteId) throws MsoException { CloudSite cloudSite = cloudConfig.getCloudSite(cloudSiteId).orElseThrow(() -> new MsoCloudSiteNotFound(cloudSiteId)); Quantum neutronClient = getNeutronClient(cloudSite, tenantId); try { Network network = findNetworkById(neutronClient, networkId); if (network == null) { logger.info("{} Network not found! Network id: {} Cloud site: {} Tenant: {} ", MessageEnum.RA_DELETE_NETWORK_EXC, networkId, cloudSiteId, tenantId); return false; } OpenStackRequest<Void> request = neutronClient.networks().delete(network.getId()); executeAndRecordOpenstackRequest(request); logger.debug("Deleted Network {} ({})", network.getId(), network.getName()); } catch (OpenStackBaseException e) { MsoException me = neutronExceptionToMsoException(e, "Delete Network"); throw me; } catch (RuntimeException e) { MsoException me = runtimeExceptionToMsoException(e, "DeleteNetwork"); throw me; } return true; }  NetworkInfo createNetwork(String cloudSiteId, String tenantId, NetworkType type, String networkName,
            String provider, List<Integer> vlans); NetworkInfo queryNetwork(String networkNameOrId, String tenantId, String cloudSiteId); Optional<Port> getNeutronPort(String neutronPortId, String tenantId, String cloudSiteId); boolean deleteNetwork(String networkId, String tenantId, String cloudSiteId); NetworkInfo updateNetwork(String cloudSiteId, String tenantId, String networkId, NetworkType type,
            String provider, List<Integer> vlans); Network findNetworkByNameOrId(Quantum neutronClient, String networkNameOrId); Network findNetworkByName(Quantum neutronClient, String networkName);  }### Answer:
@Test public void deleteNetworkkTest() throws Exception { StubOpenStack.mockOpenStackGetNeutronNetwork(wireMockServer, "GetNeutronNetwork.json", "43173f6a-d699-414b-888f-ab243dda6dfe"); StubOpenStack.mockOpenStackDeleteNeutronNetwork(wireMockServer, "43173f6a-d699-414b-888f-ab243dda6dfe"); Boolean result = msoNeutronUtils.deleteNetwork("43173f6a-d699-414b-888f-ab243dda6dfe", "tenantId", "MTN13"); Assert.assertTrue(result); }
