[英]Django with MSSQL giving error :'DatabaseWrapper' object has no attribute 'Database'
[英]testing Django with standard Unittest: 'DatabaseWrapper' object has no attribute 'Database'
我試圖逐個單獨測試Django測試文件,因為由於運行繁重的應用程序,。/ ./manage.py test
在每次運行后凍結5秒。
這是我的測試(盡管還沒有測試,只是處理請求):
if __name__ == "__main__":
import unittest
# manually get all the django stuff into memory if file is called directly
import os,sys
TEST_ROOT = os.path.realpath(os.path.dirname(__file__))
PROJ_AND_TEST_ROOT = os.path.dirname(os.path.dirname(TEST_ROOT))
PROJECT_ROOT = os.path.join(PROJ_AND_TEST_ROOT, 'the_game')
sys.path.append(PROJECT_ROOT)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "the_game.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
from django.test import TestCase, RequestFactory
from django.contrib.auth.models import User
from interface.views import bets
class ViewTests(TestCase):
def test_bets_view(self):
request_factory=RequestFactory()
request=request_factory.get('/')
user = User.objects.create_user('testname','test@na.me','testname')
request.user=user
response=bets(request)
print response
if __name__ == "__main__":
unittest.main()
但是,運行此命令,我得到以下信息:
======================================================================
ERROR: test_bets_view (__main__.ViewTests)

該項目本身完美運行,沒有錯誤( ./manage.py runserver
),Django測試( ./manage.py test ../tests
)也是如此。
我怎樣才能解決這個問題?
ps這不是該問題的重復項。 它的作者在進行標准Django測試時遇到了問題,盡管它在我的項目中正常工作。 我的麻煩是第三方測試。
不幸的是,您所做的還不足以初始化django的設置系統。 您可以嘗試以下方法:
from django.core.management import setup_environ
from mysite import settings
setup_environ(settings)
或者,您可以考慮編寫一個自定義管理命令(它將已經初始化設置系統)來調用測試運行程序。
