[FIXED] Error when reverse url with multiple arguments - Django

Issue

I'm writing a test for an url, problem is it fails when I try to pass multiple arguments, here is some code:

#test_urls.py
from django.test import SimpleTestCase
from django.urls import reverse, resolve
from cardiotesting.views import *

class TestUrls(SimpleTestCase):
    def test_new_cardio(id_patient, protocol):
        id_patient = '05'
        protocol = 'fox'
        url = reverse('new_cardio_testing', args=[id_patient, protocol])
        print(resolve(url))

#urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('new/<str:id_patient>', views.new_cardio_testing, name='new_cardio_testing'),
]

#views.py
def new_cardio_testing(id_patient, protocol):
    pass

When I run the test it returns:

.E
======================================================================
ERROR: test_new_cardio_testing (cardiotesting.tests.test_urls.TestUrls)
----------------------------------------------------------------------
TypeError: TestUrls.test_new_cardio_testing() missing 1 required positional argument: 'protocol'

But when there is only one argument the test succeeds. Appreciate any help.

Solution

test methods just take one parameter and that is self, so your test class must be something like this:

class TestUrls(SimpleTestCase):
    def test_new_cardio(self):
        id_patient = '05'
        protocol = 'fox'
        url = reverse('new_cardio_testing', args=[id_patient, protocol])
        print(resolve(url))
