量角器可以定位和检查自举angularjs的ng-for创建的列表元素吗？

Question

当在量角器中运行时，下面的代码

    describe('todomvc angular2 tests', function() {
      it('add to-dos and verify that they are displayed', function() {

        browser.ignoreSynchronization = true; // The site/app under test uses AngularJS in what might be called a manually bootstrapped fashion, i.e. without use the ng-app directive.
        browser.get('http://todomvc.com/examples/angular2/');

        browser.driver.sleep(1000); // There's got to be a better way to wait for the custom  tag (which is a custom AngularJS directive) to load.

        var el = element(by.css('input.new-todo'));
        el.clear();
        el.sendKeys('task 1\r\n');
        el.sendKeys('task 2\r\n');

        browser.driver.sleep(2000); // aid in debugging

        var resultlist = element.all(by.repeater('todo in todoStore.todos')); // This doesn't work...
        expect(resultlist.count()).toEqual(2);

      });
    });

生成以下输出：

    Using the selenium server at http://localhost:4444/wd/hub
    [launcher] Running 1 instances of WebDriver
    F

    Failures:

      1) todomvc angular2 tests add to-dos and verify that they are displayed
       Message:
         Expected 0 to equal 2.
       Stacktrace:
         Error: Failed expectation

在todoStore.todos（即ul.todo-list）中查找和检查项目的最佳方法（或任何工作方法）是什么？

量角器应该能够很好地看到这些元素。我想知道元素是否没有按照预期进行解析？看看这个promise是否可行:

$$('[ng-repeat="todo in todoStore.todos"]').count().then(function(countOfElements){
    expect(countOfElements).toEqual(2, 'Error: Todo count did not match');
})
