用Python中的virtualenv测试我的GAE应用程序

我试图在本地运行的GAE应用程序上使用unittest测试我的数据存储

当我在数据存储上运行简单查询时，我从virtualenv中得到一个错误：

Error

测试功能：

def get_conversation_id_from_email(email_user):
    """
    Args:
      email_user: the email user

    Returns:
       the conversation id
    """
    user_list = User.query(User.emails == email_user).fetch(use_cache=True, use_memcache=True)
    if len(user_list) == 0:
        return None
    for user_match in user_list:
        return user_match.device_ids[0]

在项目的根目录中创建

appengine\u config.py

，并放置以下内容：

import os
from google.appengine.ext import vendor

vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib'))

另外，若项目根目录不存在，则将

lib

包添加到项目根目录中

在我的例子中，它解决了这个问题。
