Estas en windows? Creo que es un issue de la libreria con windows. Arranca con los test de unidad (Corre esos solos con pytest test/test_unit.py) y yo me fijo si encuentro algo mas de info.

Saludos.

[Alexissiminkowich]

Sisi, es windows. Para hacer pytest de unidad como me mencionas funciona bien.

[RodrigoJacznik]

Alexis, podes probar con reemplazar el contenido de test_e2e.py con lo siguiente

import unittest
import os
import time
import threading

from selenium import webdriver

from app import create_app, db
from app.models import Product, Order, OrderProduct

basedir = os.path.abspath(os.path.dirname(__file__))

class Ordering(unittest.TestCase):
    # Creamos la base de datos de test
    def setUp(self):
        self.app = create_app()
        self.app.config.update(
            SQLALCHEMY_DATABASE_URI='sqlite:///' + os.path.join(basedir, 'test.db'),
            SQLALCHEMY_TRACK_MODIFICATIONS=False,
            TESTING=True
        )
        self.app_context = self.app.app_context()
        self.app_context.push()

        self.baseURL = 'http://localhost:5000'

        db.session.commit()
        db.drop_all()
        db.create_all()

        # start the Flask server in a thread
        threading.Thread(target=self.app.run).start()

        # give the server a second to ensure it is up
        time.sleep(1)

        self.driver = webdriver.Chrome()

    def test_title(self):
        driver = self.driver
        driver.get(self.baseURL)
        add_product_button = driver.find_element_by_xpath('/html/body/main/div[1]/div/button')
        add_product_button.click()
        modal = driver.find_element_by_id('modal')
        assert modal.is_displayed(), "El modal no esta visible"

    def tearDown(self):
        db.session.remove()
        db.drop_all()
        self.driver.close()

Pudiste probar? Actualice el repo para que funcionen los test con selenium desde Windows

[Alexissiminkowich]

Puse en el test_e2e.py lo que me pasaste pero sigue dando el mismo error. Igualmente, ahora voy a tratar de hacer algun test de unidad... tuve una semana ocupada con el tema de mi señora y casi no me pude sentar a trabajar. Saludos

[Alexissiminkowich]

Rodrigo, supuestamente ya tengo todo actualizado a su ultima version, en tag 4.0.2, tambien ya corri el pip install -r requirements.txt

Pero al tirar pytest me tira lo siguiente, igualmente voy a seguir creando los test que pueda:

Recuerdo: Uso WIN 7 32 bit,

Lo que hice fue "borrar" el test def test_title(self) de ustedes poniendo # para ignorarlo (era el que me tiraba el error). Así continuo con los de unidad mientras tanto

Hola Alexis, me parece que te falto instalar chromedriver y ponerlo en el path de windows. Te paso el link de chromedriver. Si tenes algún problema avísame y lo revisamos

[Alexissiminkowich]

Ya baje el ChromeDriver 2.39 , al ejecutarlo me abre una pantalla de cmd con lo siguiente:

Starting ChromeDriver 2.39.562718 (9a2698cba08cf5a471a29d30c8b3e12becabb0e9) on port 9515 Only local connections are allowed.

Y no hace nada. Despues de hacer eso sigo intentanto el pytest con el test de ejemplo de integracion y sigue dando el mismo error

[RodrigoJacznik]

Esta bien, el único paso que te falto es agregar al path de windows la carpeta donde esta el chromdriver.exe

[Alexissiminkowich]

Mil gracias!! (cuantas vueltas para que ande jaja). Voy a intentar hacer los de integración, disculpen la hora... trabaje todo el día y sumado visita al medico por mi mujer. Este tema esta terminado ya, me ejecuto bien el test de integración de ejemplo de ustedes.

Saludos!

Genial, no hay drama. Cualquier cosa subi una issue
