Url Django testing

urls.py of my web application is as follows

urlpatterns = [
    path('u/<int:unit_id>/', views.unit_view, name='unit_view'),
    path('u/<int:unit_id>/edit/', views.unit_edit, name='unit_edit'),
]

I triedn to write tests for urls are as following

from django.urls import reverse, resolve
from django.test import TestCase


class TestUrls(TestCase):

    def test_unit_view_url(self):
        path = reverse('unit_view', kwargs={'unit_id': 1})
        self.assertEqual('unit_view', resolve(path).views.unit_view)

    def test_unit_edit_url(self):
        path = reverse('unit_edit', kwargs={'unit_id': 1})
        assert resolve(path).views.unit_edit == 'unit_edit'

Getting error as

ERROR: test_unit_view_url (decentmark.tests.test_urls.TestUrls)
