Question

我在运行样本测试时遇到问题。

import unittest
from automation.models import Accountproperty

class TestEx(unittest.TestCase):

   def test_get_data_from_database(self):
       Accountproperty.objects.count()

if __name__ == "__main__":
unittest.main()

当我从shell运行此测试时，我没有问题：

C:\Users\apodar\PycharmProjects\autoTest>python manage.py shell
Python 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from automation.models import *
>>> Accountproperty.objects.count()
490
>>>

但是当我以这种方式运行测试时，我遇到以下问题：

C:\Users\apodar\PycharmProjects\autoTest>python manage.py test 
interface.tests.testEx.TestEx

Creating test database for alias 'default'...

有条件的信息：我使用PyCharm作为IDE，Django 1.11.4，cx-Oracle 5.2，Python 2.7.5，selenium 2.42.0

我的范围是使用selenium创建python测试，它也使用数据库连接（以某种方式在单元测试中引导应用程序）

如果有必要，请告诉我更多信息。请帮忙。非常感谢你。
