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] || ['', ''];
          }
        });

      }
    };
  }
]);

My test is:

我的测试是:

fdescribe('MedPickerController', function() {
    var $scope;

    beforeEach(function() {
      module('mapApp');

      var html = '<dosing-frequencies></dosing-frequencies>';

      inject(function($compile, $injector) {
        var $controller, $rootScope, $httpBackend;
        $rootScope = $injector.get('$rootScope');
        $httpBackend = $injector.get('$httpBackend');

        $httpBackend.whenGET('/views/directives/dosingFrequencies.html').respond(200);

        $scope = $rootScope.$new();

        var elem = angular.element(html);
        var compiled = $compile(elem)($scope);

        var controller = elem.controller();

        $scope.$digest();

      });
    });

    it('should extend the scope', function() {
        expect($scope.model).not.toBeUndefined();
    });
});

However, my test fails. The console.log in my controller also doesn't execute. What am I doing incorrect?

但是,我的测试失败了。我的控制器中的console.log也不会执行。我做错了什么?

Make the controller by itself. Don't make it an anonymous function.

自己制作控制器。不要使它成为匿名函数。

So instead of

而不是

{
  // ... some directive options
  controller: function() {
    //  Your controller's logic
  }
}

Do something like this.

做这样的事情。

{
// ... some directive options
  controller: "MedPickerController"
}

And then define your controller separately just like you would any other controller. You could even put them in the same file, it doesn't matter.

然后单独定义您的控制器就像您使用任何其他控制器一样。你甚至可以将它们放在同一个文件中,这没关系。

Then at that point you're just writing controller tests. You don't have to be concerned that it's a directive.

那时你就是在编写控制器测试。你不必担心它是一个指令。
