PyTest插件失敗，IO錯誤：在Mac OS X「不支持的XML-RPC協議」

Question

當py.test使用插件加載的xmlrpclib試車運行失敗：

INTERNALERROR> Traceback (most recent call last):

我已驗證xmlrpclib將與一個簡單的測試程序一起工作，該程序從圖片中刪除py.test。

#!/usr/bin/env python 

import xmlrpclib 
import bugzilla 
import sys 
for i in sys.path: 
    print i 

url = 'https://bugzilla.redhat.com/xmlrpc.cgi' 
u = ' ' 
p = ' ' 

try: 
    proxy = xmlrpclib.ServerProxy(url) 
except(), e: 
    print e 
b = bugzilla.Bugzilla(url=url) 
b.login(u,p) 
bug = b.getbugsimple('12345') 
print bug 

上面的程序在執行時會按預期返回。我對這裏發生的事情感到不知所措。我甚至在py.test和上面的測試程序中都添加了print sys.path，並且發現路徑與test.py和/ usr/local/bin的執行目錄/ Users/esammons的例外相同py.test。

爲了進一步排除我將/usr/local/bin/py.test和/usr/local/bin/py.test-2.7複製到項目根目錄的問題，也發生了同樣的錯誤。

謝謝！

該問題是由我的cfg文件中的值的格式造成的。我使用ConfigParser來解析我的配置文件; cfg文件具有以下格式。

[DEFAULT] 
key = value 
key2 = value 
key3 = value 

該問題是由於我用引號（'value'）包裝值引起的。具體做法是：

WRONG

bugzilla_url = 'https://bugzilla.example.com/xmlrpc.cgi' 

RIGHT

bugzilla_url = https://bugzilla.example.com/xmlrpc.cgi
