tests.py file

from django.urls import reverse
from django.urls import resolve
from django.test import TestCase
from .views import home

class HomeTests(TestCase):
    def test_home_view_status_code(self):
        url = reverse('home')
        response = self.client.get(url)
        self.assertEquals(response.status_code, 200)

    def test_home_url_resolves_home_view(self):
        view = resolve('/')
        self.assertEquals(view.func, home)

urls.py

from django.contrib import admin
from django.urls import path
from boards import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('homepage/', views.home, name='home'),
]

python version 3.6.2 django version 2.1.1

thank you in advance.

Answer 1

You do not have any URL on / only on /admin/... and /homepage in your urls.py.

So you would have to change resolve('/') to resolve('/homepage/')

Answer 2

In the test.py file, you have to make changes to resolve the argument.

def test_home_url_resolves_home_view(self):

    view = resolve('/homepage/')
    self.assertEquals(view.func, home)
