量角器:检查数据按日期排序

Question

我需要检查返回的数据是按日期排序的.这就是我写它的方式:

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;
            }
        }
    )
})

返回:

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

我究竟做错了什么？currentUser和lastUser似乎是对象而不是文本......但我不确定为什么.

获取所有出生日期map()的列表,将字符串列表转换为日期列表,并与同一数组的排序版本进行比较:

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);
});
