@Test void findAllTest() { List<TipsAndTricks> tipsAndTricks = Collections.singletonList(ModelUtils.getTipsAndTricks()); PageRequest pageRequest = PageRequest.of(0, 2); Page<TipsAndTricks> page = new PageImpl<>(tipsAndTricks, pageRequest, tipsAndTricks.size()); List<TipsAndTricksDtoResponse> dtoList = Collections.singletonList(ModelUtils.getTipsAndTricksDtoResponse()); PageableDto<TipsAndTricksDtoResponse> pageableDto = new PageableDto<>(dtoList, dtoList.size(), 0,1); when(tipsAndTricksRepo.findAllByOrderByCreationDateDesc(pageRequest)).thenReturn(page); when(modelMapper.map(tipsAndTricks.get(0), TipsAndTricksDtoResponse.class)).thenReturn(dtoList.get(0)); PageableDto<TipsAndTricksDtoResponse> actual = tipsAndTricksService.findAll(pageRequest); assertEquals(pageableDto, actual); }
