### Question:
PanelServiceImpl extends ServiceImpl<PanelMapper, Panel> implements PanelService { @Override public List<PanelDto> getPanelByItemCatId(@NonNull Long itemCatId) { List<Long> ids = new ArrayList<Long>() { { add(itemCatId); } }; return getPanelByItemCatId(ids); } @Autowired  PanelServiceImpl(PanelMapper panelMapper, ConvertService convertService,
			ItemMapper itemMapper, PanelContentMapper panelContentMapper); @Override List<PanelDto> getPanelByRemark(@NonNull String remark,
			@NonNull Integer panelLimit, @NonNull Integer itemLimit); @Override List<PanelDto> getPanelByItemCatId(@NonNull Long itemCatId); @Override List<PanelDto> getPanelWithItemsByItemCatId(@NonNull Long itemCatId,

			@NonNull Integer limit); @Override List<PanelDto> getPanelWithItemsByItemCatId(@NonNull List<Long> itemCatIds,
			@NonNull Integer itemLimit); @Override PanelDto getPanelById(@NonNull Integer panelId); @Override List<PanelDto> getPanelByItemCatId(@NonNull List<Long> itemCatIds);  }### Answer:
@Test public void getPanelByItemCatId() { List<PanelDto> list = panelService.getPanelByItemCatId(1L); Assert.assertNotNull(list); }
