單元測試角度視圖

Question

有一個視圖，該按鈕的角度指令ng禁用，綁定到某些模型屬性。複雜的是，該按鈕位於<li>標籤內。

我想要做的是設置模型屬性，編譯視圖，然後根據模型屬性的值檢查按鈕是否被正確啓用或禁用;但是，當我嘗試編譯時，列表爲空：僅有< ul標籤。

有沒有辦法完成我想要做的事情？

這裏是我的代碼：

-----------------觀點-------------------

<div ng-show="group.AreItemsExpanded"> 
    <div> 
     <ul> 
      <li ng-repeat="item in group.Items"> 
       <div> 
        {{item.Name}} 
       </div> 
       <div> 
        <button id="btn" type="button" ng-click="clickItem(item)" 
          ng-disabled="!permissions.IsAllowed || !item.IsClickable"> 
         Click! 
        </button> 
       </div> 
      </li> 
     </ul> 
    </div> 
</div>

describe('testing view', function(){ 
    beforeEach(module('groups.templates')); 

    var $scope; 
    var item; 
    var $templateCache; 
    var $compile; 

    beforeEach(inject(function($rootScope, _$templateCache_, _$compile_){ 
     $templateCache = _$templateCache_; 
     $compile = _$compile_; 
     item = { 
      Name: 'testitem0', 
      IsClickable: false 
     }; 
     $scope = $rootScope.$new(); 
     $scope.group = { 
      Items: [item], 
      AreItemsExpanded: true 
     }; 
     $scope.permissions = {IsAllowed: false}; 
    })); 

    describe('testing button', function(){ 
     it('should be enabled', function(){ 
      $scope.group.Items[0].IsClickable = true; 
      $scope.permissions.IsAllowed = true; 
      var html = $templateCache.get('view.html'); 
      var view = $compile(angular.element(html))($scope); 
      expect(view.find('button')[0].disabled).toEqual(false); 
     }); 
     it('should be disabled', function(){

      $scope.permissions.IsAllowed = true;

     }); 
    }); 
});

發現問題。所有這一切都在分配後失蹤了聲明

$scope.$digest(); 

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