Не удаётся запустить тесты в одной сессии браузера. Проходит только первый тест.

Проблема (Вопрос) заключается …
Не удаётся запустить тесты в одной сессии браузера.

Я попытался сделать …
Вынес фикстуру в корень проекта и указал scope="session"

У меня получилось …
Запускается только первый тест. Ошибка на втором тесте.

Ошибка
test_add_group.py .F
test_add_group.py:11 (test_add_empty_group)
app = <fixture.application.Application object at 0x0389F790>

    def test_add_empty_group(app):
>       app.session.login(username="admin", password="secret")
Что заметил:

Если запускать каждый тест отдельно, то всё проходит успешно.
Проблема возникает когда запускаю тесты все сразу, т.е. правый клик по папке testRun pytest in test

Если в первом тесте ( test_add_group) поставить time.sleep(1) после app.session.logout(), то тест проходит. Потом успешно запускается и проходит тест test_add_empty_group, но потом так же возникает ошибка только на 3-м тесте, на методе app.session.login(...)

Такое ощущение что не “успевает” кликнуть по ссылке “Logout”.
Дебажил. Если в браузере в том моменте когда зависает тест сам кликну по ссылке “Logout”, то всё нормально идёт дальше.

Бьюсь 2-й день. Может у кого-то были подобные случаи? Или есть какие-то мысли?

Был бы очень рад помощи! Спасибо!)))

Судя по коду, вы выполняете домашнее задание на курсе А.Баранцева. Почему вы не спросите у него или в чате учеников?
Попробуйте разделить fixture def app на def app и def stop с addfinalizer


(Andy) #3

Увы, не был на курсах А. Баранцева. Вопрос задавать неудобно так как пользуюсь материалом из просторов интернетов)


(Andy) #4

Не совсем представляю как это будет работать.

В def app создаётся экземпляр класса Application где как раз и инициализируется WebDriver. В этом же классе есть метод def destroy, который завершает работу драйвера.

def app передаётся тестам качества в параметра тестам. Т.е. одна фикстура управляет всеми тестами.

Как должна выглядеть def stop с addfinalizer отдельно?


(Andy) #5

Что ещё попробовал:

  1. Изменил селектор. Вместо искать по имени find_element_by_name изменил на find_element_by_css_selector - ошибка осталась.
  2. Добавил time.sleep(1) в метод def logoutв классе SessionHelper после клика- ошибки нет
Теперь код выглядит так:
import time


class SessionHelper:

    def __init__(self, app):
        self.app = app

    def login(self, username, password):
        wd = self.app.wd
        self.app.open_home_page()
        wd.find_element_by_css_selector("input[name='user']").click()
        wd.find_element_by_css_selector("input[name='user']").clear()
        wd.find_element_by_css_selector("input[name='user']").send_keys(username)
        wd.find_element_by_css_selector("input[name='pass']").click()
        wd.find_element_by_css_selector("input[name='pass']").clear()
        wd.find_element_by_css_selector("input[name='pass']").send_keys(password)
        wd.find_element_by_css_selector("input[type='submit']").click()

    def logout(self):
        wd = self.app.wd
        # Logout
        wd.find_element_by_css_selector("form[name='logout'] > a").click()
        time.sleep(1)

Это нормальные костыли или есть лучше практика? Или вообще причина может быть в другом? Спасибо!


(Александр Литовский) #7

Нет, это не нормально. Попробуйте в логине проверять, есть ли кнопка логаут, уберите все слипы.


(Andy) #8

Ошибка осталась.

Из сообщения test_add_group.py .Element: form[name=‘logout’] > a exists понятно, что элемент успешно находится.


(Александр Литовский) #9

Вместо try catch можно было
if len(wd.find_elememts_by_xxx(xxxxx))>0:
print (“элемент есть”)
else
print (“элемента нет”)
пишу с телефона, не самое удобное, значения подставите
А так, можно проверять, что logout исчез, поставить здесь явное ожидание вместо sleep(1)


(Andy) #10

Сделал 2 варианта и с if и с implicit waits. Оба работают, но вот что смущает:

if len(…) > 0

почему тест проходит успешно если отработал блок в login():

else:
    print("!!!Code that shouldn't be shown")

Implicit waits

Так же и здесь. Как выполняется этот код?

else:
    print("Scope Login: $(\"" + self.elem_logout + "\") - Element exists")

Если бы элемент logout был на странице login, то мы бы не смогли авторизоваться.

процент пройденных тестов


(Andy) #12

Странно. Тесты прошли все, а показывает разный процент.

Screen


(Александр Литовский) #13

Итоговый 100%


(Andy) #14

Понял, т.е. прогресс показывает по конкретному файлу с тестами. Процент относительно общего кол-ва файлов с тестами.

Правильно понял, проблема имеете 2 решения?

Сообщение: Не удаётся запустить тесты в одной сессии браузера. Проходит только первый тест.

Там же есть 2 вопроса, может есть какие то мысли?


(Александр Литовский) #15

Есть ссылка на github ?


(Andy) #16

Проверил сотый раз под дебагом на Firefox. Ошибки нет. Но если обычно запустить, то ошибка.
Так же ошибка под Edge

Ошибки нет под chromedriver


Firefox обновлённый до 65.0, драйвер последний v0.24.0
Edge 17.17134, драйвер от сюда Release 17134


Ошибку не решил, копаю дальше. Временно тесты буду гонять только под хромом.
Если есть предположения, мысли - ПИШИТЕ! У меня голова уже кругом)))
