I am developing a Next.js app and when I started making some tests with selenium-webdriver I started to get some problems. My webapp uses authentication with Metamask wallets. The problem is when trying to import a wallet on a test window with selenium to be able to log in after this in my webapp. I have tried a lot of ways to do it:
- JavaScript tests trying to download metamask or trying to open a new chromewindow with metamask installed
- Python tests with auto-metamask, trying to import metamask in a new window...
I am on ubuntu 22.04. Chrome version is 113.0.5672.92, chromedriver version is 113.0.5672.63, selenium-webdriver version is 4.9.1, python3 version is 3.10.6.
This is the code:
import time
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
def test_login_button():
EXTENSION_PATH = '/nkbihfbeogaeaoehlefnkodbefgpgknn-10.30.1-www.Crx4Chrome.com.crx' # Path from the crx downloaded file in my pc (I have tried a bunch of them downloaded from different sites)
SECRET_RECOVERY_PHRASE = "my seed phrase"
NEW_PASSWORD = "password"
opt = webdriver.ChromeOptions()
opt.add_extension(EXTENSION_PATH)
#opt.add_argument("--disable-extensions-except=nkbihfbeogaeaoehlefnkodbefgpgknn") (this approach does not work, I tried to disable all extensions except metamask but it does not work when executing the code because it does not find the extension)
#opt.add_argument("--user-data-dir=./path/to/google-chrome/Profile 1") (this approach did not work when trying to open an existing profile)
driver = webdriver.Chrome(options=opt)
time.sleep(3)
driver.switch_to.window(driver.window_handles[1])
time.sleep(3)
wait = WebDriverWait(driver, 30)
element = wait.until(EC.presence_of_element_located((By.XPATH, '//button[text()="Importar una cartera existente"]'))) # This is the line which gives an error
element.click()
#driver.find_element(By.XPATH, '//*[text()="Importar una cartera existente"]').click()
# Rest of the code
ERROR obtained:
> element = wait.until(EC.element_to_be_clickable((By.XPATH, '//*[text()="Importar una cartera existente"]')))

I have followed different tutorials:
- Main one is: https://dev.to/ltmenezes/automated-dapps-scrapping-with-selenium-and-metamask-2ae9
- auto-metamask library: https://pypi.org/project/auto-metamask/
- Metamask automation with Selenium webdriver
I just want to be able to make some tests to interact with a metamask wallet for my application to be able to log in it and then interact with the smart contracts that provide the logic.
