Realizar una prueba técnica

Clase 23 de 24 • Curso de Introducción a Selenium con Python

Para utilizar location, condition y higher_price cambie el código. El mensaje de Selenium fue "Element click intercepted".

# Anterior 
location.click()
# Nuevo
driver.execute_script("arguments[0].click();", location)

Con eso logre realizar el test.

Este es mi implementación antes de ver el vídeo, mi intención era generalizarlo lo mas posible para cualquier variación como país, búsqueda, filtro, localidad y orden.

Mucho cuidado con el botón de cookies. Como bien es sabido, el chromedriver ejecuta en incógnito. Cuando tú estás revisando mucho ++ojo++, porque cuando exploras, lo haces hasta con tu cuenta ya ingresada, y claro, con las cookies ya guardadas. Pero es muy diferente, cuando ingresas en incógnito, porque allí te pide que o aceptes o rechaces las cookies, por ser la "primera vez" que ingresas.

Para ello, debes poner este código dentro del ejercicio de la clase:

Después de buscar el playstation y antes de hacer el filtro de ubicación:

cookies_in = driver.find_element_by_xpath("/html/body/div[2]/div[1]/div[2]/button[1]")
cookies_in.click()
sleep(3)

Y eso es todo, te funcionará perfecto.

++Consejo: ++ Al hacer un script de automatización y que vayas haciendo la exploración de la página web, realiza la exploración en incógnito, pues así garantizas el comportamiento normal que se tendría con el chromedriver, que es una especie de incógnito.

Espero les sirva...

en mi caso lo use antes de buscar playstation despues no me funciona

Marzo-2021. Sale este error: Message: Element <span class="ui-search-filter-name"> is not clickable at point (113,643) because another element <div id="cookieDisclaimerBanner" class="nav-cookie-disclaimer"> obscures it. Parece que usaron alguna cookie para bloquear busquedas automatizadas con Selenium (por ejemplo), F. De todas maneras gran curso

No es problema, debes usar la solucion mencionada en los anteriores post:

location=driver.find_element_by_partial_link_text('Bogotá D.C.')
driver.execute_script("arguments[0].click();", location)

Creo que es mejor usar un diccionario en vez de dos listas

 products = {}

Al final de la prueba pon sleep(60) y te dará un minuto para que puedas comprobar que todo se aplicó correctamente Para agregar sleep solo importas el módulo time

tengo entendido que el metodo "find_element_by" fue eliminado en selenium desde la version 4.3. Es posible trabajar hoy en dia con este curso?

Es totalmente posible solo debes cambiar tu código donde sea necesario, eso si, vas a tener que ir solucionando errores debido a la actualización, en esa función en específico te dejo la documentación: Link

El Xpath que menciona el profe, no me sirvió dado que cambia un poco la estructura de la lista de producto en la web de mercado libre, para eso hice un xpath más flexible, que captura los productos a pesar de los cambios en cada recarga

        for i in range(8):
            article_name = driver.find_element(By.XPATH, f'//li[{i + 1}]//h2').text
            articles.append(article_name)
            article_price = driver.find_element(By.XPATH, f'//li[{i + 1}]//span[contains(@class, "andes-money-amount__fraction")]').text
            prices.append(article_price)

        for i in range(8):
            print(articles[i], "| Precio:", prices[i])

Es el segundo curso que veo de Hector Vega , y la verdad hay temas que quedan claros por que son sencillos , pero no porque explique bien , ; en general el no explica nada bien ,solo hace y hace código , da ganas de dormirse antes que ver el curso , no se sabe incluso ni que va hacer , pesimo curso. sobre 10 , le doy un 6/10
