概述

当我运行manage.py test abcapp时,我写的所有测试都通过了.

当我运行manage.py测试时,我遇到了一连串的失败.显示了第一个失败：

Traceback (most recent call last):
  File "C:\Program Files\Django-1.5b1\django\core\handlers\base.py",line 116,in get_response
    response = callback(request,*callback_args,**callback_kwargs)
  File "C:\Program Files\Django-1.5b1\django\views\decorators\cache.py",line 89,in _wrapped_view_func
    response = view_func(request,*args,**kwargs)

    getattr(messages,message_type)(request,msg)
  File "C:\Program Files\Django-1.5b1\django\contrib\messages\api.py",line 70,in debug
    fail_silently=fail_silently)
  File "C:\Program Files\Django-1.5b1\django\contrib\messages\api.py",line 22,in add_message
    raise MessageFailure('You cannot add messages without installing '
MessageFailure: You cannot add messages without installing django.contrib.messages.middleware.MessageMiddleware

测试结果如下：

======================================================================
FAIL: test_clearsessions_command (django.contrib.sessions.tests.FileSessionTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "C:\Program Files\Django-1.5b1\django\test\utils.py",line 213,in inner
    return test_func(*args,**kwargs)
  File "C:\Program Files\Django-1.5b1\django\contrib\sessions\tests.py",line 444,in test_clearsessions_command
    self.assertEqual(1,count_sessions())
AssertionError: 1 != 2

----------------------------------------------------------------------
Ran 474 tests in 5.768s

Failed (failures=1,skipped=141,expected failures=1)

与消息相反,我的MIDDLEWARE_CLASSES中有django.contrib.messages.middleware.MessageMiddleware.我的MIDDLEWARE_CLASSES的值如下.我在我的应用程序中使用消息没有任何问题.

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware','django.contrib.sessions.middleware.SessionMiddleware','django.middleware.csrf.CsrfViewMiddleware','django.contrib.messages.middleware.MessageMiddleware','django.contrib.auth.middleware.AuthenticationMiddleware','debug_toolbar.middleware.DebugToolbarMiddleware',)

任何人都可以对这个问题有所了解吗？虽然我只能运行自己的测试,但我希望运行整个套件以确保适当的质量控制.

研究结果：我通过自己的测试注意到,当使用测试http客户端时,没有加载任何中间件.当我试图通过测试客户端中的Web请求测试我自己的中间件时,我发现了这一点.如果是这种情况,这是否意味着djanog核心中存在不可测试的代码？

这是问题File-based session does not store any data on Windows.
建议的解决方法：在django / contrib / sessions / backends / file.py中用shutil.move替换os.rename：

+import shutil

....

 -os.rename(output_file_name,session_file_name)

 +shutil.move(output_file_name,session_file_name)

Original patch
