Python 3.x WSGI测试框架

Question

鉴于webtest似乎没有3.x版本（或任何开发一个的计划），是否有解决方案来自动化系统测试WSGI应用程序？我知道单元测试的单元测试 - 我对整个系统测试的时刻更感兴趣。

我不是在寻找工具来帮助开发一个应用 - 只需测试它。

Answer 1

如果有其他人出现这种情况，我最终自己写了一个解决方案。
下面是我使用的一个非常简单的类 - 我只是从WSGIBaseTest而不是TestCase继承而来，并获得可以将请求传入的方法self.request()。
它存储cookies，并将自动将它们发送到后续请求中的应用程序（直到调用self.new_session()）。

import unittest 
from wsgiref import util 
import io 

class WSGIBaseTest(unittest.TestCase): 
    '''Base class for unit-tests. Provides up a simple interface to make requests 
    as though they came through a wsgi interface from a user.''' 
    def setUp(self): 
     '''Set up a fresh testing environment before each test.''' 
     self.cookies = [] 
    def request(self, application, url, post_data = None): 
     '''Hand a request to the application as if sent by a client. 
     @param application: The callable wsgi application to test. 
     @param url: The URL to make the request against. 
     @param post_data: A string.''' 
     self.response_started = False 
     temp = io.StringIO(post) 
     environ = { 
      'PATH_INFO': url, 
      'REQUEST_METHOD': 'POST' if post_data else 'GET', 
      'CONTENT_LENGTH': len(post), 
      'wsgi.input': temp, 
      } 
     util.setup_testing_defaults(environ) 
     if self.cookies: 
      environ['HTTP_COOKIE'] = ';'.join(self.cookies) 
     self.response = '' 
     for ret in application(environ, self._start_response): 
      assert self.response_started 
      self.response += str(ret) 
     temp.close() 
     return response 
    def _start_response(self, status, headers): 
     '''A callback passed into the application, to simulate a wsgi 
     environment. 

     @param status: The response status of the application ("200", "404", etc) 
     @param headers: Any headers to begin the response with. 
     ''' 
     assert not self.response_started 
     self.response_started = True 
     self.status = status 
     self.headers = headers 
     for header in headers: 
      # Parse out any cookies and save them to send with later requests. 
      if header[0] == 'Set-Cookie': 
       var = header[1].split(';', 1) 
       if len(var) > 1 and var[1][0:9] == ' Max-Age=': 
        if int(var[1][9:]) > 0: 
         # An approximation, since our cookies never expire unless 
         # explicitly deleted (by setting Max-Age=0). 
         self.cookies.append(var[0]) 
        else: 
         index = self.cookies.index(var[0]) 
         self.cookies.pop(index) 
    def new_session(self): 
     '''Start a new session (or pretend to be a different user) by deleting 
     all current cookies.''' 
     self.cookies = []
