Protractor: inspection data is sorted by date

Question

I need to check that the returned data is sorted by date. This is how I write it:

it('should be sorted by date', function() { element.all(by.repeater('users in group.users')).then( function(users) { var lastUser = users[0].element(by.id('birth-date')).getText(); for (var i = 1; i < users.length; ++i) { var currentUser = users[i].element(by.id('birth-date')).getText(); expect(moment(currentApplication).format('MMM d, YYYY HH:mm')).toBeGreaterThan(moment(lastApplication).format('MMM d, YYYY HH:mm')); lastUser = currentUser; } } ) }) 

This returns:

 Expected 'Jan 1, 2015 00:00' to be greater than 'Jan 1, 2015 00:00'. 

What am I doing wrong? currentUser and lastUser seem to be objects instead of text ... but I'm not sure why.

Answer 1

Get a list of all birthdays using map() , convert the list of strings to a list of dates, and compare with a sorted version of the same array:

 element.all(by.id('birth-date')).map(function (elm) { return elm.getText().then(function (text) { return new Date(text); }); }).then(function (birthDates) { // get a copy of the array and sort it by date (reversed) var sortedBirthDates = birthDates.slice(); sortedBirthDates = sortedBirthDates.sort(function(date1, date2) { return date2.getTime() - date1.getTime() }); expect(birthDates).toEqual(sortedBirthDates); }); 

Answer 2

I did a little research on this topic. My code is:

 element.all(by.id('birth-date')).map(function (elm) { return elm.getText(); }).then(function (birthDates) { var sortedbirthDates = birthDates.slice(); sortedbirthDates = sortedbirthDates.sort(function compareNumbers(a, b) { if (a > b) { return 1; } }); expect(birthDates).toEqual(sortedbirthDates); }); 

Here we are not dependent on the type of value. We can use it for numbers, strings and dates.
