Question

我是棱角分明的新手，我正试图处理测试，但是在一个看似愚蠢的问题上已经被困了一段时间，也许这对于$ compile缺乏了解。我将我的单元测试代码简化为以下内容：

it('should create a table', inject(['$compile', '$rootScope', function ($compile, $rootScope) {
    var element;
    var scope = $rootScope.$new();
    scope.list = [{name: 'tst'},{name:'sae'},{name:'dkos'}]
    element = angular.element('<ul><li ng-repeat="p in list">{{p.name}}</li></ul>');
    element = $compile(element)(scope);
    expect(element.find('li').length).to.equal(3);
}]));

当我经营业力时，我收到以下失败：

我正在撕裂我的头发，所以任何帮助都会很棒！如果有必要，我很乐意提供更多细节。

在调用scope.$digest()之后，看起来需要调用$compile()才能使ng-repeat在列表上运行。所以你的测试可能就像：

it('should create a table', inject(['$compile', '$rootScope', function ($compile, $rootScope) {
  var element;
  var scope = $rootScope.$new();
  scope.list = [{name: 'tst'},{name:'sae'},{name:'dkos'}]
  element = angular.element('<ul><li ng-repeat="p in list">{{p.name}}</li></ul>');
  element = $compile(element)(scope);
  scope.$digest();
  expect(element.find('li').length).toEqual(3);
}]));

$ compile不在单元测试中工作
