### Question:
InventoryEstimateDaoESImp extends BaseDaoESImp implements InventoryEstimateDao { @Override public Impression getPredictions_PI_TCs(Day day, List<TargetingChannel> tcs) throws IOException, JSONException { if (CommonUtil.isEmpty(tcs)) { return new Impression(); } BoolQueryBuilder boolQueryBuilder = createAndQueryForSingleValue(tcs); return getPredictionsForQuery(day, boolQueryBuilder); } InventoryEstimateDaoESImp();  InventoryEstimateDaoESImp(Properties properties); @Override DayImpression getHourlyPredictions(TargetingChannel targetingChannel,
                                              double tbrRatio); @Override Impression getPredictions_SIGMA_TCs_PI_BNs(Day day, List<TargetingChannel> tcs, List<TargetingChannel> bns); @Override Impression getPredictions_PI_TCs_DOT_qBAR(Day day, List<TargetingChannel> tcs, TargetingChannel q); @Override Impression getPredictions_PI_BNs_MINUS_SIGMA_BMs_DOT_q(Day day, List<TargetingChannel> bns, List<TargetingChannel> bms, TargetingChannel q); @Override Impression getPredictions_SIGMA_BMs_PLUS_qBAR_DOT_BNs(Day day, List<TargetingChannel> bms, TargetingChannel q, List<TargetingChannel> bns); @Override Impression getPredictions_PI_TCs(Day day, List<TargetingChannel> tcs); @Override Map<Day, Impression> aggregatePredictionsFullDaysWithRegionRatio(TargetingChannel targetingChannel,
                                                                            Set<Day> days); @Override Map<Day, Impression> aggregatePredictionsFullDays(TargetingChannel targetingChannel, Set<Day> days);  }### Answer:
@Test public void getPredictions_PI_TCs() throws IOException { InventoryEstimateDaoESImp invEstImp = new InventoryEstimateDaoESImp(DEF_PROP); invEstImp.setESClient(DEF_ESCLI); List<TargetingChannel> tcs = new ArrayList(), bns = new ArrayList(); TargetingChannel tc1 = new TargetingChannel(), tc2 = new TargetingChannel(), tc3 = new TargetingChannel(); tc1.setA(Arrays.asList("2")); tc1.setG(Arrays.asList("g_m")); tc2.setA(Arrays.asList("3")); tc3.setR(Arrays.asList("456")); tcs.add(tc1); tcs.add(tc2); tcs.add(tc3); Impression res = invEstImp.getPredictions_PI_TCs(DEF_DAY, new ArrayList()); String exp = "{{h:0,t:h0}{h:0,t:h1}{h:0,t:h2}{h:0,t:h3}}"; assertEquals(exp, res.toString()); res = invEstImp.getPredictions_PI_TCs(DEF_DAY, tcs); assertNotNull(res); assertEquals(exp, res.toString()); }
