Sorting An array in Protractor

Question

I am using protractor for my E2E testcases. In my case, I am having an array and I want to sort it

Ex.

Arraylist.push(elements[1].getText());

Arraylist.push(elements[2].getText());

Arraylist.push(elements[0].getText());

element[n] is returning a text value which is getting inserted into the ArrayList. Now I want to Sort this Array and test that the elements are in the correct order.

Do someone has idea, How can we do that?

Can you clarify why you would like to print the sorted values? My understanding of E2E tests using Protractor is that the output are is successful expectations. — Michal Charemza

My testcase is to compare that whenever user click on header of an list, the items under it should be sorted. Therefore I am inserting each element in an array so that I can sort that array too and compare with the sorted list on UI. — Amit

To do this, you should be aware that all the elements and return values of getText() are promises. Therefore sorting the array, and comparing the sorted with the unsorted, has to be done with the resolved results of these promises.

var unsorted = elements.map(function(element) {
  return element.getText();
});

var sorted = unsorted.then(function(texts) {
  // Make sure to copy the array to not sort the original
  return texts.slice(0).sort();
});

var equals = protractor.promise.all([unsorted, sorted]).then(function(texts) {
  var unsorted = texts[0];
  var sorted = texts[1];
  var allEqual = (unsorted.length === sorted.length);
  sorted.forEach(function(sortedItem, i) {
    allEqual = allEqual && (sortedItem === unsorted[i]);
  });
  return allEqual;
});

expect(equals).toBe(true);

not sure what the connection to E2E testing or protractor is, but well ... Arraylist.sort() or use lodash/underscorejs _.sortBy(Arraylist, sortingValue)
