### Question:
DatabaseService { public ServiceResult<List<String>> getDBCatalogs(Long dbsetId) throws Exception { if (null == dbsetId) { return ServiceResult.success(ListUtils.EMPTY_LIST); } DataBaseInfo dataBaseInfo = dataBaseDao.getMasterCologByDatabaseSetId(dbsetId); if (null == dataBaseInfo) { return ServiceResult.fail("未找到对应的表,请添加表关联！！"); } return getDBCatalogsByDbId(dataBaseInfo.getId()); }  ValidatorChain validatePermision(LoginUser user, Errors errors); ServiceResult isExist(List<String> db_names); ServiceResult<String> addDataBaseInfo(LoginUser user, DataBaseInfo dataBaseInfo); ServiceResult<String> genDefaultDbsetAndEntry(DataBaseInfo dataBaseInfo); ServiceResult<String> genDefaultDbsetAndEntry(Long groupId, Long dbId, String dbname, Integer dbtype); boolean isNotExistByName(DataBaseInfo dataBaseInfo); ServiceResult<String> checkupdateDBInfo(DataBaseInfo dataBaseInfo); boolean updateDBInfo(DataBaseInfo dataBaseInfo); ListResult<DataBaseView> findDbPageList(Paging<DataBaseInfo> paging); ListResult<DataBaseView> findDbPageListByUserId(Paging<DataBaseInfo> paging, Long userId); ServiceResult encryptAndOptUser(LoginUser user, List<DataBaseInfo> dBList); ServiceResult<String> addDataBaseList(List<DataBaseInfo> dBList); ServiceResult<List<String>> getDBCatalogs(Long dbsetId); ServiceResult<List<String>> getDBCatalogsByDbId(Long dbid); ServiceResult connectionTest(ConnectionRequest connectionRequest); ServiceResult deleteCheck(Long dbId); ServiceResult<String> addDataCenter(LoginUser user, List<DataBaseInfo> list); ServiceResult<String> updateDataCenter(LoginUser user, DataBaseInfo dataBaseInfo); ServiceResult<String> deleteDataCenter(LoginUser user, DataBaseInfo dataBaseInfo); ServiceResult<String> syncDataCenter(LoginUser user, DataBaseInfo dataBaseInfo); ConfigCkeckResult<List<ConfigDataResponse>> getCheckData(LoginUser user, DataBaseInfo dataBaseInfo); ServiceResult getDataBaseButton(LoginUser user);  }### Answer:
@Test public void getDBCatalogsTest() throws Exception { Assert.assertTrue(databaseService.getDBCatalogs(1L).getCode() == ServiceResult.SUCCESS); }
