量角器：跟进另一个有关如何处理在页面对象模型中返回数组的定位符的线程

Question

I have a follow up question on this thread here: What's the correct Protractor's syntax for Page Objects?

This post was useful in understanding page objects especially the answer by : "Xotabu4" but I am running into slightly different problem.

Could someone please help me understand how would one handle a page object that returns an array of elements in a similar model as quoted in the above link by the user. For example, element.all($$) returns an array and I have to compare each element in the array with a certain text. How do I structure that in the model mentioned in the above hyperlink

Answer 1

Assume there is a dropdown list to choose destination implement by <select> , we need to verify all options with correct text.

<select class="destination">
  <option></option>
  ....
</select>

this.select_destination = element(by.css('select.destination'));

readDestinationOptionsText() {
  return this.select_destination.all(by.css('option')).getText();
}

verifyDestinationOptionsText(expectTexts) {
  return readDestinationOptionsText().then(function(actualTexts){
     return expect(actualTexts.join(',')).toEqual(expectTexts.join(','));
  });
}
