Agregar y eliminar elementos

Steven Moreno
Usé en la línea 29:
delete_button = driver.find_element_by_class_name('added-manually')
Ya que todos los elementos a eliminar comparten la misma clase

Justo iba a comentar que a veces decide usar el xpath cuando hacer un selector CSS es una alternativa no muy complicada.

Algo que he notado, ahora que empezé a trabajar en el mundo Tech, es que no es buena idea usar el x-path para el caso de las automatizaciones, sino el ID. Aunque depende, si tienes la posibilidad de solicitar que coloquen el id a las etiquetas, debes hacerlo, así no tendras problemas cuando el código fuente cambie.
Santiago Arias
Exacto, el XPATH es como el ultimo resurso y lo mas preciso siempre sera el ID

Alguien me podría ayudar, tengo el mismo código pero ya desde hace varias clases atras, los print statements no me aparecen por consola, es como si el stdout apunte a otra direccion que no sea la consola, alguien sabe a que se debe?
Miguel Andres Rendon Reyes
¿Qué sistema operativo tienes?

ya lo pude solucionar, era porqeu estaba usando otra librería html-testRunner en lugar de pyunitreport

def test_browser_navigation(self): driver = self.driver elements_added = int(input('How many elements will you add? ')) elements_removed = int(input('How many elements will you remove?

Realice el reto haciendo que el usuario no pueda equivocarse en las cantidades, si fallara, seria por alguna otra causa, sin embargo esta controlado con el try/except
def test_add_remove(self): add = int(input('< Cuantos elementos deseas agregar? ')) remove = int(input('< Cuantos elementos deseas remover? ')) total = add - remove try: while total < 0: print('> Intentas borrar mas elementos de los que crearas, intenta de nuevo') add = int(input('< Cuantos elementos deseas agregar? ')) remove = int(input('< Cuantos elementos deseas remover? ')) total = add - remove add_button = self.driver.find_element_by_xpath('//*[@id="content"]/div/button') for _ in range (add): add_button.click() sleep(0.5) element_list = self.driver.find_elements_by_class_name('added-manually') for _ in range(remove): element = element_list.pop(0) element.click() sleep(0.5) except: print('> Ha ocurrido un error...')

He logrado que mi código funcione, sin embargo, me gustaría entender por qué si declaro el delete_button por fuera del for, dicho for solo funciona una vez y no las n veces de la variable "elements-remove"
Omar Daniel Centeno
¡Hola! :)
Si pudieras compartirnos tu código sería más sencillo encontrar la solución. Puedes copiar y pegar utilizando el botón de </> insertar código.
¡Saludos!

por que no manejar testcomplete pregunta ?

ProfesorVeo que tienes 2 métodos de prueba en tu script, sin embargo estos deben tener la palabra test al inicio o de lo contrario el módulo unittest no los identificará y no los ejecutará.

¿Como soluciono si la version del "chromedriver" esta desactualizada respecto a Chrome? este error me aparece :
"session not created: This version of ChromeDriver only supports Chrome version 93 Current browser version is 95.0.4638.54 with binary path /Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
fidel angel ochoa
ya lo solucione, segui los mismos pasos que se muestran en la clase "hola mundo" de este curso, elimine de mi carpeta el antiguo chromedriver, descargue el nuevo de la pagina de chrome y lo estraje en la carpeta de los archivos donde tengo el entorno virtual de selenium.

Para hacerlo todo por el navegador solo con alertboxes y sin usar la consola como en la imagen.
Vean esta propuesta, quiza con el tiempo la mejore.

Por alguna razón de la existencia existencial, no me permite hoy en día (16 de agosto, 2022) el pedir un user input (quizás alguien mas podría confirmar eso), pero para poder cumplir el reto, tuve la idea de usar números al azar mediante RANDOM. Les comparto mi código final:

Aquí funciona correctamente
<import unittest from selenium import webdriver from time import sleep class AddRemoveElements(unittest.TestCase): def setUp(self): self.driver = webdriver.Chrome( executable_path=r'C:\Users\aleja\Documents\Visual Studio Code\s2\chromedriver.exe') driver = self.driver driver.get('<URL>') def test_add_remove(self): driver = self.driver add = int(input('Cantidad a agregar: ')) add_button = driver.find_element_by_xpath('/html/body/div[2]/div/div/button') remove = int(input('Cantidad a eliminar: ')) for i in range (add): add_button.click() if remove > add: remove = add for i in range (remove): button_remove = driver.find_element_by_xpath('/html/body/div[2]/div/div/div/button[1]') button_remove.click() total_elements = add-remove if total_elements < 0: print(f'Hay 0 elementos en pantalla') else: print(f'Hay {total_elements} elementos en pantalla') sleep(5) def tearDown(self): self.driver.implicitly_wait(3) self.driver.close() if __name__ == "__main__": unittest.main(verbosity=2)>
Sin embargo, si hago esto no funciona correctamente, solo hace click una vez en delete
button_remove = driver.find_element_by_xpath('/html/body/div[2]/div/div/div/button[1]') ***(resto del código antes de esta línea)*** for i in range (remove): button_remove.click()```
No entiendo por qué, pero ahora no se me abre el navegador.
