在我的博客上发布的新闻的页面，是提供给任何用户。我使用pytest来检查页面是否可以被匿名用户访问。Url是通过使用新闻的id形成的，我将其传入地址参数（作为元组）。
结果我得到了这个类型错误。test_pages_availability[news：detail-news] - TypeError：需要字符串或类似字节的对象
我曾尝试将args格式化为str，在tuple格式的args后放置一个逗号，但没有帮助
试验规程

@pytest.mark.django_db
@pytest.mark.parametrize(
    'name, args',
    (
        ('news:detail', pytest.lazy_fixture('news')),
        ('news:home', None),
        ('users:login', None),
        ('users:logout', None),
        ('users:signup', None),
    )
)
def test_pages_availability(client, name, args):
    if args is not None:
        url = reverse(name, args=(news.id,))
    else:
        url = reverse(name)
    response = client.get(url)
    assert response.status_code == HTTPStatus.OK

固定装置

@pytest.fixture
def news():
    news = News.objects.create(
        title='Новость',
        text='Невероятное событие',
        date=datetime.today,
    )
    return news

class NewsDetail(generic.DetailView):
model = News
template_name = 'news/detail.html'

def get_object(self, queryset=None):
    obj = get_object_or_404(
        self.model.objects.prefetch_related('comment_set__author'),
        pk=self.kwargs['pk']
    )
    return obj

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    if self.request.user.is_authenticated:
        context['form'] = CommentForm()
    return context

追溯：

request = <FixtureRequest for <Function test_pages_availability[news:detail-news]>>

def fill(request):
    item = request._pyfuncitem
    fixturenames = getattr(item, "fixturenames", None)
    if fixturenames is None:
        fixturenames = request.fixturenames

    if hasattr(item, 'callspec'):
        for param, val in sorted_by_dependency(item.callspec.params, fixturenames):
            if val is not None and is_lazy_fixture(val):

item.callspec.params[param] = request.getfixturevalue(val.name)
