basic example warning and some questions

[catafest-work]

I tested this :

import pytest
import warnings
from pylenium.driver import Pylenium
from pylenium.config import PyleniumConfig

# Ignoră warning-urile specifice
warnings.filterwarnings("ignore", category=pytest.PytestAssertRewriteWarning)

# Fixture pentru Pylenium
@pytest.fixture
def py():
    config = PyleniumConfig()
    py = Pylenium(config=config)
    yield py
    # Comentăm linia care închide browserul automat
    # py.quit()

# Test simplu folosind Pylenium
def test_example(py):
    py.visit('http://127.0.0.1:5000')
    py.get('h1').should().have_text('Add User') 

if __name__ == "__main__":
    pytest.main()

and I got this warnings:

Seam the:

warnings.filterwarnings("ignore", category=pytest.PytestAssertRewriteWarning)

not work and the browser is close even I comment the :

 # py.quit()

Why is need to rewrite: 'Module already imported so cannot be rewritten: faker' ?
