protractor - how to get the result of an array of promises into another array

Question

I got an array of promises from this code: element.all(by.repeater(\'unit in units\')), and I am finding it really difficult to get the data into another array:

Answer 1

Managed to get the same result on a simpler way avoiding using Q and the repeater. Using the inbuilt map does the trick.

var tabs = element.all(by.css('.unitTabs li a')).map(function (elm) {
    return elm.getText();
});

tabs.then(function (result) {
    var sorted = _.sortBy(result, function (name) { return name; });
    for (var i = 0; i < result.length; i++) {
        expect(result[i]).toBe(sorted[i]);
    }
});

Answer 2

npm Q is the first thing to do then use requirejs on top of your script like that

      var Q = require('q');

      element.all(by.repeater('object in objects')).then(function (arr) {
          var promises = [];
          for (var i = 0; i < arr.length; i++) {
              promises.push(arr[i].getText());
          }

          Q.all(promises).done(function (result) {
              // print the results when the lookups and processing are done
              console.log(result.length);
              console.log(result);
          });
      });

BTW I think my second option it is cleaner.

Answer 3

Fixed using Q

var Q = require('q');

element.all(by.repeater('unit in units')).then(function (arr) {
    var promises = [];
    for (var i = 0; i < arr.length; i++) {
        promises.push(arr[i].getText());
    }

    Q.all(promises).done(function (result) {
        // print the results when the lookups and processing are done                
        console.log(result.length);
        console.log(result);                
    });
});
