Starting with the basics of getting an enterprise project up and running, you'll get to grips with maintaining the project throughout its lifecycle while learning what the Django application lifecycle is.

Testing HTTP view requests

In this section, we will expand on the basic test cases that we previously wrote to include HTTP view requests. When testing view classes, whether they are a method-based view or a class-based view, they will both use the same TestCase class that we have been using so far.

In the following subsections, we will perform two tests, one for a method-based view and the other for a class-based view.

Testing method-based views

In this exercise, we will test the practice_year_view() method, written in Chapter 4, URLs, Views, and Templates. What we are comparing in this test is whether the response code that gets returned equals the value of 200, which means a successful response.

Follow these steps to create your test case:

  1. In your /chapter_9/tests.py file, add the following YearRequestTestCase class and methods:
    # /becoming_a_django_entdev/chapter_9/tests.py
...
from django.contrib.auth.models import AnonymousUser
from django.test import ......
