Instanz des Direktiven-Controllers mit Angular/Jasmine

Question

Beim Testen von Winkeldirektiven: Wie kann ich eine Instanz des Directive Controllers greifen und bestimmte Datenbindungen auf dem Controller bestätigen?

function myDirective() { 
    return { 
    restrict: 'E', 
    replace: true, 
    templateUrl: 'tpl.html', 
    scope: { }, 
    controller: function($scope) { 
     $scope.text = 'Some text'; 
    } 
    }; 
} 

angular 
    .module('example') 
    .directive('myDirective', [ 
    myDirective 
    ]); 

Unit-Test

describe('<my-directive>', function() { 
     var element; 
     var $compile; 
     var $scope; 

     beforeEach(module('example')); 

     beforeEach(function() { 
     inject(function(_$compile_, _$rootScope_) { 
      $compile = _$compile_; 
      $scope = _$rootScope_.$new(); 
     }); 
     }); 

     describe('basic functionality', function() { 
     beforeEach(function() { 
      element = $compile('<my-directive></my-directive')($scope); 
      $scope.$digest(); 
     }); 

     it('should bind the correct text', function() { 
      //? 
     }); 
     }); 
    }); 

Answer 1

element = $compile('<my-directive></my-directive')($scope); 
$scope.$digest(); 
ctrl = element.controller('myDirective'); 

Answer 2

Anruf element.controller mit $scope wie element.controller($scope). Einige Nachweise des Konzepts.

angular 
 
    .module('example', []) 
 
    .directive('myDirective', [ 
 
    function myDirective() { 
 
     return { 
 
     restrict: 'E', 
 
     replace: true, 
 
     //template: ['<div>{{ text }}</div>'].join(''), 
 
     scope: {}, 
 
     controller: function($scope) { 
 
      $scope.text = 'Some text'; 
 
     } 
 
     }; 
 
    } 
 
    ]); 
 

 
describe('<my-directive>', function() { 
 
    var element; 
 
    var $compile; 
 
    var $scope; 
 

 
    beforeEach(module('example')); 
 

 
    beforeEach(function() { 
 
    inject(function(_$compile_, _$rootScope_) { 
 
     $compile = _$compile_; 
 
     $scope = _$rootScope_.$new(); 
 
    }); 
 
    }); 
 

 
    describe('basic functionality', function() { 
 
    beforeEach(function() { 
 
     element = $compile('<my-directive></my-directive')($scope); 
 
     $scope.$digest(); 
 
    }); 
 

 
    it('should bind the correct text', function() { 
 
     expect(element.controller($scope).scope().$$childTail.text).toEqual('Some text') 
 
    }); 
 
    }); 
 
});
