AlertsService { boolean adjustmentsHaveBeenMadeForEachCommodityInMonthOfAlert(final Date date) { final Date low = Helpers.firstDayOfMonth(date); final Date high = Helpers.lastDayOfMonth(date); final List<Commodity> commoditiesFromAdjusments = from(getAdjustmentsBetweenDates(low, high)).transform(new Function<Adjustment, Commodity>() { @Override public Commodity apply(Adjustment input) { return input.getCommodity(); } }).toList(); List<Commodity> commoditiesWithoutAdjusments = from(commodityService.all()).filter(new Predicate<Commodity>() { @Override public boolean apply(Commodity input) { return !commoditiesFromAdjusments.contains(input); } }).toList(); return commoditiesWithoutAdjusments.size() == 0; }  List<LowStockAlert> getLowStockAlerts(); List<LowStockAlert> getEnabledLowStockAlerts(); int numberOfAlerts(); int getNumberOfRoutineOrderAlerts(); List<LowStockAlert> getTop5LowStockAlerts(); void updateLowStockAlerts(); void updateCommodityLowStockAlert(Commodity commodity); void updateCache(); void disableAlertsForCommodities(List<Commodity> commodities); void disableAllRoutineOrderAlerts(); ImmutableList<LowStockAlert> getLowStockAlertsForCommodities(final List<Commodity> commodities); void createAlert(final LowStockAlert lowStockAlert); void disableLowStockAlert(LowStockAlert alert); void deleteLowStockAlert(final LowStockAlert alert); void updateLowStockAlert(final LowStockAlert lowStockAlert); List<OrderCommodityViewModel> getOrderCommodityViewModelsForLowStockAlert(); int getRoutineOrderAlertDay(); void generateRoutineOrderAlert(Date date); List<? extends NotificationMessage> getNotificationMessagesForHomePage(); List<? extends NotificationMessage> getNotificationMessages(); List<MonthlyStockCountAlert> getEnabledMonthlyStockAlerts(); List<OrderCommodityViewModel> getOrderViewModelsForRoutineOrderAlert(); void generateAllocationAlerts(); List<AllocationAlert> getAllocationAlerts(); void deleteAllocationAlert(final Allocation allocation); void generateMonthlyStockCountAlerts(Date date); int getMonthlyStockCountDay(); List<MonthlyStockCountAlert> getMonthlyStockCountAlerts(final Date date); void disableAllMonthlyStockCountAlerts(); static final String DISABLED; static SimpleDateFormat ALERT_DATE_FORMAT; }### Answer:
@Test public void shouldCheckIfAdjustmentsHaveBeenMadeForEachCommodityInMonthOfAlert() throws Exception { setupCommodities(); Adjustment adjustment = new Adjustment(commodityService.all().get(0), 10, true, AdjustmentReason.PHYSICAL_COUNT.getName()); saveAdjusment(adjustment); assertThat(alertsService.adjustmentsHaveBeenMadeForEachCommodityInMonthOfAlert(new Date()), is(false)); createAdjustmentsForEachCommodity(new Date()); assertThat(alertsService.adjustmentsHaveBeenMadeForEachCommodityInMonthOfAlert(new Date()), is(true)); }
