Question

我在尝试django unittests库时遇到了几个问题。发生了一些奇怪的事情：

我定义了这样的测试：

from django.core import management
from django.test import TestCase
from django.test.client import Client
from django.core import mail
from django.test.utils import setup_test_environment
from django.contrib.auth.models import User
from django.db import connection
from goserver.models import ActiveList

class GoserverTestCase(TestCase):
    #fixtures = ['dat.json']

    def setUp(self):
        pass

    def test_active_list_works(self):
        c = Client()
        response = c.post('/')
        #print response.status_code
        self.assertEquals(True, True)

但是在执行代码之后它会返回以下错误：

----------------------------------------------------------------------  Unit Test Code Coverage Results

    execute_manager(settings)   File "/opt/local/lib/python2.5/site-packages/Django-1.0.2_final-py2.5.egg/django/core/management/__init__.py", line 340, in execute_manager

    raise AlreadyRegistered('The model %s is already registered' % model.__name__) django.contrib.admin.sites.AlreadyRegistered: The model ActiveList is already registered silver:jin oleg$

管理员文件如下所示：

from goserver.models import ActiveList, Game
from django.contrib import admin

class ActiveListAdmin(admin.ModelAdmin):
    list_display = ('user', "is_Bot", "isActive")

admin.site.register(ActiveList, ActiveListAdmin)
admin.site.register(Game)

我这样运行： python manage.py test goserver

还注意到如果我删除行 c =客户（） response = c.post（'/'）

从测试用例定义

，然后没有出现错误

Answer 1

查看回溯，看起来您有一个名为django_test_coverage-0.1的应用，它正在导入您应用的admin.py。

可能是从其他位置导入，例如yourproject.yourapp.admin而不是yourapp.admin。由于它在技术上被视为一个不同的模块，因此会重新导入它并再次进行admin.site.register调用。这会导致AlreadyRegistered错误。

我的建议是删除django_test_coverage app（或修复它）。

Answer 2

我的问题，

我不知道什么是TestCase的基类型/类 - 是Django Test one还是Unittest？最好从Django使用
你怎么跑步测试？使用Django内部测试命令，通过鼻子，通过unittest？通过Traceback I thing test命令，但我不太确定。
您对ActiveAdminList和ActiveList的定义是什么？你有没有在Meta的课程管理员？

我解决了这个问题，注意了proye

中的admin.autodiscover（）行
