Python 3.x WSGI 测试框架

鉴于 webtest 似乎没有 3.x 版本(或任何开发计划),是否有任何用于 WSGI 应用程序的自动化系统测试的解决方案?我知道用于单元测试的 unittest - 我对整个系统测试的时刻更感兴趣。

我不是在寻找帮助开发应用程序的工具 - 只是测试它。

最佳答案

为了防止其他人遇到这种情况,我最终自己编写了一个解决方案。
这是我使用的一个非常简单的类 - 我只是从 WSGIBaseTest 而不是 TestCase 继承,并获得一个方法 self.request() 我可以将请求传递进去。
它存储cookies,并会在以后的请求中自动将它们发送到应用程序中(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 = []
