### Question:
PaaSOfferingRecommendation implements eu.cloud4soa.api.soa.PaaSOfferingRecommendation { @Override public void updateUserExperienceRate(String appURI, String rate) throws SOAException { logger.debug("Update User experience rate for appURI: " + appURI); int intRate = Integer.parseInt(rate); if ((intRate < 1) || (intRate > 5)) { throw new IllegalArgumentException(); } else { userExperienceRate.updateUserExperienceRate(appURI, intRate); } }  @Required void setBreachRepository(BreachRepository breachRepository); @Required void setApplicationProfilesRepository(ApplicationProfilesRepository applicationProfilesRepository); @Required void setApplicationInstanceRepository(ApplicationInstanceRepository applicationInstanceRepository); @Required void setUserExperienceRate(UserExperienceRate userExperienceRate); @Override void storeUserExperienceRate(String appURI, FiveStarsRate rate); @Override void deleteUserExperienceRate(String appURI); @Override FiveStarsRate getUserExperienceRate(String appURI); @Override void updateUserExperienceRate(String appURI, String rate); @Override List<FiveStarsRate> getPaaSUserExperienceEvaluation(String paasURI); @Override float getAveragePaaSUserExperienceRate(String paasURI); @Override float getPaaSBreachesPerWeek(String paasURI); @Override float getPaaSBreachesPerMonth(String paasURI); @Override float getPaaSBreachesPerDay(String paasURI);  }### Answer:
@Test public void testUserExperienceRateUpdate() throws Exception { String newRateValue; UserExperienceRate rateToModify; UserExperienceRate modifiedRate; newRateValue = "3"; logger.debug("Getting the Rate and verifying the value"); rateToModify = userExperienceRateDao.getUserExperienceRateByAppUri( APP3TEST_URIID ); assertTrue( "The loaded rate doesn't have the expected value", RATE2_VALUE == rateToModify.getRate().intValue() ); logger.debug( "Modifying and updating the rate on the database"); paasOfferingRecommendation.updateUserExperienceRate( APP3TEST_URIID, newRateValue ); logger.debug( "Verifying the rate has been modified"); modifiedRate = userExperienceRateDao.getUserExperienceRateByAppUri( APP3TEST_URIID ); assertTrue( "The rate hasn't been modified", Integer.parseInt(newRateValue) == modifiedRate.getRate().intValue() ); }
