$timeout 中的以下代码永远不会被调用。我可以在那里放置任何我喜欢的错误测试并且测试总是通过(有一个类似的问题(Karma e2e testing: how to know when the DOM is ready?)但它没有提供解决方案):

it('should display a filter row when attribute sg-live-filtering is present', function()   
{
   angular.mock.inject(function($compile, $rootScope, $timeout) {
      var elem = $compile('<div sg-grid sg-data="api/grid/accounts" sg-live-filtering></div>')(scope); // the angular-kendo grid
      $rootScope.$apply();            
      var table = elem.find('table[role="grid"]'); // find the kendo grid
      expect(table.length).toBe(1);
      var header = table.find('thead'); // find the grid's table header 
      expect(header.length).toBe(1);
      $timeout(function () {
         // get the second row in the header and check it has a specific class
         expect(header.find('tr').eq(1).hasClass('sg-grid-filter-row')).toBeTruthy();
         // e.g. I could do this and it would still pass!!!             
         expect(header.find('tr').eq(500));
      });
   }
}

这是它在浏览器中的样子:

在此处输入图像描述

剑道网格是使用标准 angularjs 指令创建的:

angular.module('sgComponents').directive('sgGrid', [
   templateUrl: 'sg-grid.html',
   // lots of kendo code follows to build the grid       
]);

外部 sg-grid.html 模板:

<div sg-grid sg-data="api/grid/accounts"             
     sg-live-filtering> <!-- the attribute I want to test -->        
</div>

当指令代码运行时,会检查是否存在 sg-live-filtering attr。如果是,则调用实用程序函数将您在图像中突出显示的行附加到网格的表头

if (attrs.sgLiveFiltering) {
   /*
    timeout is needed to ensure DOM is ready. COULD THIS BE THE PROBLEM?
   */
   $timeout(function () { 
      /*
      this function adds the filter row to the grid. 
      THE NEW ROW HAS CLASS 'sg-grid-filter-row' THAT I USE FOR TESTING
      */
      buildGridFilterRow(elm, scope, attrs);
    });
}

你能显示你的测试代码吗???因为您必须等待才能执行超时或仅使用 $timeout.flush(); 这是一个例子: Unit testing an asynchronous service in angularjs

最后(2周后!)让它工作。@idursun 和 igorzg 在建议使用 $timeout.flush(100) 时是正确的,但正如 @idursun 在他的评论中进一步提到的那样,它还需要删除 $timeout 块。

当我最初尝试这个时,它没有用,但现在它可以了。不要问我为什么,我只关心它是否有效!这是我的完整测试用例供参考:

it('should display a filter row when attribute sg-live-filtering is present', function () {
   angular.mock.inject(function($compile, $rootScope, $timeout) {
   var scope = $rootScope.$new();
   scope.accountColumnsForAdvSearch = [
      {field: 'accountId', title: 'AccountId', dataType: 'string'},
      {field: 'name', title: 'Account Name', dataType: 'string'},
      {field: 'shortName', title: 'Short Name', dataType: 'string'},
      {field: 'status', title: 'Status', dataType: 'string'}
   ];

   $httpBackend.when('GET', 'api/grid/accounts').respond(accountData);    

   var elem = $compile('<div sg-grid sg-data="api/grid/accounts" sg-columns="accountColumnsForAdvSearch" sg-live-filtering="true"></div>')(scope);
   $rootScope.$apply();
   $httpBackend.flush();
   $timeout.flush(100); // wait for DOM to load
   var table = elem.find('table[role="grid"]'); // the kendo grid
   expect(table.length).toBe(1);
   var filterRow = table.find('.sg-grid-filter-row'); // the filter row
   expect(filterRow.length).toBe(1);
});
