Why does this test fail?

[Johann Spies]

I am new to Testing Driven Development as well as to Django and will appreciate some help please.

I have just worked through the tutorials of the official documentation for 1.11 and am trying
to get going with TDD and Django.

The app is wos_2017_2 and I get this in the shell (which is run in the project root)

in the app's urls.py I have

>>> from django.test import Client
>>> client = Client()
>>> response = client.get('/')
Not Found: /
>>> response = client.get('/wos_2017_2/')
>>> response
.status_code
200

from . import views

from django.conf.urls import url

urlpatterns = [
 url(r'^$', views.index, name='index'),

]

and the in "wos_2017_2/test.py"

import unittest
from django.test import TestCase
from django.test import Client


# Create your tests here.

from .models import *
from .views import *

class SimpleTest(unittest.TestCase):

    def test_index(self):
        client = Client()
        response = client.get('/')
        self.assertEqual(response.status_code, 200)

And the test fails with

FAIL: test_index (wos_2017_2.tests.SimpleTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/js/django/wos/wos_2017_2/tests.py", line 16, in test_index
    self.assertEqual(response.status_code, 200)
AssertionError: 404 != 200

----------------------------------------------------------------------
Ran 1 test in 0.006s

Using the url

http://localhost:8000/wos_2017_2/

in a browser works as expected.

My question was answered on Stackoverflow:

The correct line in the function should be

response = client.get('/wos_2017_2/')


because of my project urls.py that I did not provide initially:

urlpatterns = [
 url(r'^wos_2017_2/', include('wos_2017_2.urls')),
 url(r'^admin/', admin.site.urls),
]
