### Question:
SpecManagementServiceImpl implements SpecManagementService { @Override public synchronized void updateContainerConfig(final String serverTemplateId, final String containerSpecId, final Capability capability, final ContainerConfig containerConfig) { final ServerTemplate serverTemplate = templateStorage.load(serverTemplateId); if (serverTemplate == null) { throw new KieServerControllerIllegalArgumentException("No server template found for id " + serverTemplateId); } final ContainerSpec containerSpec = serverTemplate.getContainerSpec(containerSpecId); if (containerSpec == null) { throw new KieServerControllerIllegalArgumentException("No container spec found for id " + containerSpecId + " within server template with id " + serverTemplateId); } final List<Container> affectedContainers = updateContainerConfig(capability, containerConfig, serverTemplate, containerSpec); if (affectedContainers.isEmpty()) { logInfo("Update of container configuration resulted in no changes to containers running on kie-servers"); } affectedContainers.forEach(ac -> { logDebug("Container {} on server {} was affected by a change in the scanner", ac.getContainerSpecId(), ac.getServerInstanceKey()); }); containerSpec.getConfigs().put(capability, containerConfig); templateStorage.update(serverTemplate); notificationService.notify(new ServerTemplateUpdated(serverTemplate)); }  @Override synchronized void saveContainerSpec(String serverTemplateId,

@Test public void testUpdateContainerConfigWhenContainerConfigIsNotAProcessConfigNeitherARuleConfig() { final SpecManagementServiceImpl specManagementService = spy((SpecManagementServiceImpl) this.specManagementService); final Capability capability = Capability.PROCESS; final ContainerConfig containerConfig = mock(ContainerConfig.class); final ServerTemplate serverTemplate = mock(ServerTemplate.class); final ContainerSpec containerSpec = mock(ContainerSpec.class); final List<?> expectedContainers = new ArrayList<>(); final List<Container> actualContainers = specManagementService.updateContainerConfig(capability, containerConfig, serverTemplate, containerSpec); assertEquals(expectedContainers, actualContainers); }
