如何在AngularJS指令中对控制器进行单元测试？

My directive is:

我的指示是:

window.map.directive('dosingFrequencies', [
  function() {
    return {
      restrict: 'E',
      scope: true,
      templateUrl: '/views/directives/dosingFrequencies.html',
      controller: function($scope, util) {
console.log('here we go!');

        angular.extend($scope, {
          model: createModel(),

          addFrequency: function(med) {
            med.frequencies.push(createFreqModel());
          },

          removeFrequency: function(med, index) {
            med.frequencies.splice(index, 1);
          },

          showTimeChecked: function(freq) {
            if (freq.showTime) {
              freq.prn = false;
              freq.quantity = '';
              freq.quantityWhole = '';
              freq.quantityFrac = '';
              resetTimeToFirstLast(freq, this.model.facilityTimezone)
            }
            if (!freq.showTime) {
              for (var z = 0; z < freq.doses.length; z++) {
                freq.doses[z].quantity = '';
                freq.doses[z].quantityWhole = '';
                freq.doses[z].quantityFrac = '';
              }
              resetTimeToAllday(freq, this.model.facilityTimezone);
            }
          },

          updateDosingForm: function(med) {
            med.template.dosingForm = doseUnitChoices[med.med.dosingUnit] || ['', ''];
          }
        });

      }
    };
  }
]);
