djangoのtest(django-nose, coverage)を使用する時

djangoでtestをするとき、django-nose、coverageが使える。

$ pip install nose
$ pip install django-nose
$ pip install coverage
  • settigns.py
INSTALLED_APPS += ['django_nose', ]
TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'
NOSE_ARGS = [
    '--with-coverage',  # coverage を取る
    '--cover-html',
    '--cover-package=app.search,
    '--nocapture',
    '--nologcapture',
]

tests.py

import unittest
from django.test import Client

class SimpleTest(unittest.TestCase):
    def setUp(self):
        # Every test needs a client.
        self.client = Client()

    def test_details(self):
        # Issue a GET request.
        response = self.client.get('/customer/details/')

        # Check that the response is 200 OK.
        self.assertEqual(response.status_code, 200)

        # Check that the rendered context contains 5 customers.
        self.assertEqual(len(response.context['customers']), 5)
