Python third-party library series 18--python/django test Library

Django is a web framework for Python voice, and for Django testing you can also talk about Python testing first. Django can be tested in Python, and, of course, Django encapsulates a test library of its own based on Python.
First, the Python Test--unitest Library

def my_func (a_list, idx):    return A_list[idx]    import unittestclass myfunctestcase (unittest. TestCase):    def testbasic (self):        a = [' Larry ', ' Curly ', ' Moe ']        self.assertequal (My_func (A, 0), ' Larry ')        self.assertequal (My_func (A, 1), ' Curly ')

Second, Django Test--django.utils.unittest Library, Django.test.client Library.
(1) Django.utils.unittest Library
A higher-level reference to the Django-encapsulated unittest. By the way, there is a benefit to writing this: The test case can be used directly with Django's models, and it is very convenient to operate the database.

From django.utils import unittestfrom myapp.models import Animalclass animaltestcase (unittest. TestCase):    def setUp (self):        self.lion = Animal.objects.create (name= "Lion", sound= "Roar")        Self.cat = Animal.objects.create (name= "Cat", sound= "Meow")    def Test_animals_can_speak (self): "" "        animals that can speak is correctly identified "" "        self.assertequal (Self.lion.speak (), ' The lion says ' Roar ')        self.assertequal ( Self.cat.speak (), ' the cat says ' Meow "')

(2) Django.test.client Library
To test its service capabilities, Django, as the Web server, must impersonate a client to access server-side validation

From django.utils import unittestfrom django.test.client import Clientclass 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 OK.        Self.assertequal (Response.status_code, $)        # Check that the rendered context contains 5 customers.        Self.assertequal (Len (response.context[' customers '), 5)

Or more advanced, directly with the from Django.test.TestCase

From django.test import Testcaseclass simpletest (TestCase):    def test_details (self):        response = Self.client.get ('/customer/details/')        self.assertequal (Response.status_code, $)    def test_index (self):        response = self.client.get ('/customer/index/')        self.assertequal (Response.status_code, 200)

Third, the use of the database

If you still need to initialize the database when you test, the Testcase.fixtures help you.

Also, Django will help you create a new database name: Test_ The original database name when you test it. This prevents the real database from being soiled.

You can initialize your database in this way:

From django.test import testcasefrom myapp.models import Animalclass animaltestcase (TestCase):    fixtures = [' Mammals.json ', ' birds ']    def setUp (self):        # Test definitions as before.        Call_setup_methods ()    def testfluffyanimals (self):        # A Test that uses the fixtures.        Call_some_test_code ()

Then someone asked: How did Mammals.json come? What is the format? In fact, this file is a Python manage.py dumpdata command, the document about this command please Google. The file format is probably as follows:

[    {        "pk": 1,        "model": "Apps.animal",        "fields": {            "status": 1,            "gmt_modified": " 2015-07-06t14:05:38 ",            " gmt_created ":" 2015-07-06t14:05:38 ",            " Alive ": 1,            " info ":"        }    },    {"        pk": 2,        "model": "Apps.animal",        "fields": {            "status": 0,            "gmt_modified": " 2015-07-06t14:05:53 ",            " gmt_created ":" 2015-07-06t14:05:53 ",            " Alive ": 1,            " info ":" "        }    }]

In fact, django.test This package also has a lot of other functions, can not be enumerated, in detail, see the official Django document.
