测试.py

# write code to test the views.
from django.test import Client

# import nose for tests.
import nose.tools as noz

class TestSettings(object):
    """ test the nose test related setup """

    def setup(self):
        self.client = Client()

    def testTestUser(self):
        """ Tests if the django user 'test' is setup properly."""
        # login the test user
        response = self.client.login(username=u'test', password=u'test')    
        noz.assert_equal(response, True)

从管理命令运行此代码时，会给出以下输出：

    $ ./manage.py test <app-name>
    nosetests --verbosity 1 <app-name>
    Creating test database for alias 'default'...
    F
    ======================================================================
    FAIL: Tests if the django user 'test' is setup properly.

       self.test(*self.arg)

       noz.assert_equal(response, True)
    AssertionError: False != True

现在通过 django shell 运行时相同的命令给出以下内容：

    $ ./manage.py shell
    Python 2.6.6 (r266:84292, Sep 11 2012, 08:28:27)

    Type "help", "copyright", "credits" or "license" for more information.
    (InteractiveConsole)
    >>> from django.test import Client
    >>> 
    >>> import nose.tools as noz
    >>> 
    >>> client = Client()
    >>> response = client.login(username=u'test', password=u'test')
    >>> noz.assert_equal(response, True)
    >>> 
    >>> 
    >>> response
    True
    >>>

用户 'test' 在 django 中对于当前场景处于活动状态。

为什么我在运行管理命令时收到此错误断言？

看起来它没有继承基础测试类，所以它没有在测试之前调用 setup 方法。我会建议从 Django 的 TestCase 类继承，根据Django 文档的 testing。在这种情况下，它看起来像这样：

# write code to test the views.
from django.test import Client
import unittest

# import nose for tests.
import nose.tools as noz

class TestSettings(unittest.TestCase):
    """ test the nose test related setup """

    def setUp(self):  # Note that the unittest requires this to be setUp and not setup
        self.client = Client()

    def testTestUser(self):
        """ Tests if the django user 'test' is setup properly."""
        # login the test user
        response = self.client.login(username=u'test', password=u'test')    
        noz.assert_equal(response, True)

您是否正在为您的测试创建具有用户名test和密码的用户test？还是加载夹具？我打赌不会。

当您使用 shell 时，您正在登录 settings.py 中的数据库。当您进行测试时，您正在使用您的测试数据库，该数据库在每次测试开始时都是空的，因此没有用户。

在setUp你可以创建一个用户

from django.contrib.auth.models import User
User.objects.create('test', 'test@test.com', 'test')

正如@Kevin London 所指出的那样

你的设置命令应该是

setUp，但我认为这与它没有太大关系，因为默认情况下每个TestCase都有一个client。
