Tests:

  • using loop

     
        if (_.has(testObject, 'eligibilityGroupDates')) {
          testObject.eligibilityGroupDates.forEach(entry => {
            Object.keys(entry).forEach(key => {
              switch (key) {
                case 'eligibilityGroupDates':
                  _.set(testObject, 'displayEligibilityGroupDates', true);
                  break;
                case 'o2eStartDate':
                  _.set(testObject, 'displayO2eStartDate', true);
                  break;
                case 'numOfDaysToCalO2EStartDate':
                  _.set(testObject, 'displayNumOfDaysToCalO2EStartDate', true);
                  break;
                case 'numberOfDaysToEnroll':
                  _.set(testObject, 'displayNumberOfDaysToEnroll', true);
                  break;
                default:
                  break;
              }
            });
          });
        }

  • using JSON stringify

     
        if (_.has(testObject, 'eligibilityGroupDates')) {
          let value = JSON.stringify(testObject.eligibilityGroupDates);
          if (value.indexOf('eligibilityGroups') > 0) {
            _.set(testObject, 'eligibilityGroups', true);
          }
          if (value.indexOf('o2eStartDate') > 0) {
            _.set(testObject, 'displayO2eStartDate', true);
          }
          if (value.indexOf('numOfDaysToCalO2EStartDate') > 0) {
            _.set(testObject, 'displayNumOfDaysToCalO2EStartDate', true);
          }
          if (value.indexOf('numberOfDaysToEnroll') > 0) {
            _.set(testObject, 'displayNumberOfDaysToEnroll', true);
          }
        }
