В случае, если кто-то еще столкнется с этим, я сам в конечном итоге написал решение.
Вот очень простой класс, который я использую - я просто наследую от WSGIBaseTest
вместо TestCase
и получаю метод self.request()
, в который я могу передавать запросы.
Он сохраняет cookies
и автоматически отправляет их в приложение при последующих запросах (до вызова self.new_session()
).
import unittest

'''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.

self.cookies.append(var[0])
