Testing if user is not login, redirect to login page

Just testing if my application will redirect to the login page if the user is not logged in. The url /confirmation/TEST01 where TEST01 is a reverse url. It should redirect to /accounts/login/?next=/confirmation/TEST01

But I am getting an error:

AssertionError: 404 != 302 : Response didn't redirect as expected: Response code was 404 (expected 302)

Test.py

def test_redirect_to_login(self):
    response = self.client.get('/confirmation/TEST01/')
    self.assertRedirects(response, '/accounts/login/?next=/confirmation/TEST01', status_code=302, target_status_code=404, fetch_redirect_response=True)

Terminal
