我的应用程序叫做abcapp.我在
Python 2.7上运行Django 1.5b1.同样的问题发生在django的最新trunk版本中.
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)

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)

Ran 474 tests in 5.768s

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？
解决方法
这似乎是Windows版本的一个错误.
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)
