### Question:
ContainerDBServiceProviderImpl implements ContainerDBServiceProvider { @Override public void storeContainerCount(Long count) { ReconUtils.upsertGlobalStatsTable(sqlConfiguration, globalStatsDao, CONTAINER_COUNT_KEY, count); } @Inject  ContainerDBServiceProviderImpl(DBStore dbStore,
                                        Configuration sqlConfiguration); @Override void close(); @Override void initNewContainerDB(Map<ContainerKeyPrefix, Integer>
                                     containerKeyPrefixCounts); @Override void storeContainerKeyMapping(ContainerKeyPrefix containerKeyPrefix,
                                       Integer count); @Override void storeContainerKeyCount(Long containerID, Long count); @Override long getKeyCountForContainer(Long containerID); @Override boolean doesContainerExists(Long containerID); @Override Integer getCountForContainerKeyPrefix(
      ContainerKeyPrefix containerKeyPrefix); @Override Map<ContainerKeyPrefix, Integer> getKeyPrefixesForContainer(
      long containerId); @Override Map<ContainerKeyPrefix, Integer> getKeyPrefixesForContainer(
      long containerId, String prevKeyPrefix); @Override Map<Long, ContainerMetadata> getContainers(int limit,
                                                    long prevContainer); @Override void deleteContainerMapping(ContainerKeyPrefix containerKeyPrefix); @Override long getCountForContainers(); @Override TableIterator getContainerTableIterator(); @Override void storeContainerCount(Long count); @Override void incrementContainerCountBy(long count);  }### Answer:
@Test public void testStoreContainerCount() throws Exception { containerDbServiceProvider.storeContainerCount(3L); assertEquals(3L, containerDbServiceProvider.getCountForContainers()); containerDbServiceProvider.storeContainerCount(5L); assertEquals(5L, containerDbServiceProvider.getCountForContainers()); }
