The page of the published news on my blog, is available to any user. I use pytest to check if the page is accessible to an anonymous user. Url is formed by using the id of the news, which I pass in the address parameters (as a tuple).
In the result I got this Type error. test_pages_availability[news:detail-news] - TypeError: expected string or bytes-like object
I had tried to format args to str, puted a coma after arg for tuple format, it didn't helped

Your data= parameter is not a date, it is a function to convert it into a date. You need to call the method, so:
@pytest.fixture
def news():
return News.objects.create(
title='Новость',
text='Невероятное событие',
date=datetime.today(),
)For a default=… [Django-doc] you can indeed pass a callable that Django will then call, but not as a value, the value is then the result of the function call, not the function itself.
