量角器: arrayofelements.getText()上的断言返回空列表

Question

下面的断言代码在CI中不起作用(可能是因为速度慢)，但在CI中的本地系统中工作得很好，我根本得不到元素列表，或者它只返回实际元素数组中的一个或两个元素

var expectedFromLevels = ['Level 2', 'Level 3', 'Level 4'];
var expectedToLevels= ['Level 3', 'Level 4','Level 5'];
expect(dashboard.getAllFromLevels()).toEqual(expectedFromLevels)
expect(dashboard.getAllToLevels()).toEqual(expectedToLevels)//this has to be called only after getAllFromLevels is assertion is complete

//definition of getAllFromLevels()
    getAllFromLevels : {
        value: function () {
          return element.all(by.css('#from-levels .nlq-sel--level')).getText();
      }
    //definition of getAllToLevels()
    getAllToLevels : {
        value: function() {
          return element.all(by.css('#to-levels .nlq-sel--level')).getText();
          };

**Results::**
In my local system: passed

**In CI:::**
Expected [ 'Level 2', 'Level 3' ] to equal [ 'Level 2', 'Level 3', 'Level 4' ].
Expected [ 'Level 3', '' ] to equal [ 'Level 3', 'Level 4', 'Level 5' ].

我在CI中通过添加浏览器等待语句修复了这个问题-我知道这不是理想的方法，但这是暂时有效的解决方法-

    getAllLevelsCount : {
    value: function (elements, n) {
  return function () {
    return elements.count(function (count) {
      return count >= n;
    });
  };
}
browser.wait(dashboard.getAllLevelsCount($$("cssid"), 3) , 10000);
