### Question:
MetaChartSourceController extends AbstractController implements MetaChartSourceAPI { @Override @GetMapping(value = "/{sourceId}") public ResponseEntity<MetaChartSourceShowVO> show(@PathVariable Integer sourceId) { MetaChartSourceShowVO metaChartSourceShowVO = metaChartSourceService.show(sourceId); return ResponseEntity.ok(metaChartSourceShowVO); }  @Override @PostMapping @ResponseStatus(HttpStatus.CREATED) ResponseEntity<MetaChartSourceShowVO> save(@Valid @RequestBody MetaChartSourceAddDTO metaChartSourceAddDTO); @Override @PutMapping ResponseEntity<MetaChartSourceShowVO> update(@Valid @RequestBody MetaChartSourceUpdateDTO metaChartSourceUpdateDTO); @Override @PostMapping(value = "/with_items") @ResponseStatus(HttpStatus.CREATED) ResponseEntity<MetaChartSourceShowVO> saveWithItems(@Valid @RequestBody MetaChartSourceWithItemsAddDTO addDTO); @Override @PutMapping(value = "/with_items") ResponseEntity<MetaChartSourceShowVO> updateWithItems(@Valid @RequestBody MetaChartSourceWithItemsUpdateDTO updateDTO); @Override @GetMapping(value = "/{sourceId}") ResponseEntity<MetaChartSourceShowVO> show(@PathVariable Integer sourceId); @Override @GetMapping(value = "/{sourceId}/with_items") ResponseEntity<MetaChartSourceWithItemsShowVO> showWithItems(@PathVariable Integer sourceId); @Override @DeleteMapping ResponseEntity<Integer> deleteBatch(@RequestBody Integer[] id);  }### Answer:
@Test public void show() throws Exception { MetaChartSourcePO metaChartSource = metaChartSourceHelper.saveMetaChartSourceExample( this.metaProject.getProjectId(), this.metaEntity.getEntityId()); restMockMvc.perform(get(getApiPath() + "/meta_chart_source/{sourceId}", metaChartSource.getSourceId())) .andExpect(status().isOk()); }
