patch-requests
Simple patching of requests calls.
The package contains a patch_requests context manager, which can be used to
mock one or multiple calls to requests.FOO() methods. Also calls to
requests.Session().FOO() are mocked automatically.
The patch_requests context manager takes a list of expected HTTP methods to
be called, as well as their expected status codes and returned data. A single
expected call is a tuple of ("method", ("status_code (int)", "returned_data (either dict, str or bytes)")). E.g.:
with patch_requests([('get', (200, {'ids': [1, 3, 4]}))]) as cm:
assert requests.get('http://whatever').json() == {'ids': [1, 3, 4]}Some assumptions are made based on the type of given "returned data":
- if type is
dict, the return value ofresponse.json()is set to the given value - if type is
str, theresponse.textis set to the given value - if type is
bytes, theresponse.contentis set to the given value.
Upon exiting the patch_requests context, it is possible to access the mocks of
each requests calls with cm.mocks, which is a dictionary with method names as keys.
For example:
with patch_requests([('get', (200, {'ids': [1, 3, 4]}))]) as cm:
assert requests.get('http://whatever').json() == {'ids': [1, 3, 4]}
assert cm.mocks['get'].call_args_list[0][0][0] == 'http://whatever'A full example from tests.py:
import unittest
import requests
from patch_requests import patch_requests
class TestPatcher(unittest.TestCase):
def test_multiple_requests(self):
with patch_requests([
('get', (200, {1: 1})),
('post', (201, {2: 2})),
('GET', (404, '<html><p><br/>')),
('patch', (500, b'\\')),
]) as p:
response = requests.get('http://example.com')
self.assertEqual(response.status_code, 200)
self.assertEqual(response.json(), {1: 1})
s = requests.Session()
response = s.post('http://www.example.com')
self.assertEqual(response.status_code, 201)
self.assertEqual(response.json(), {2: 2})
response = s.get('http://')
self.assertEqual(response.status_code, 404)
self.assertEqual(response.text, '<html><p><br/>')
s.close()
response = requests.patch('')
self.assertEqual(response.status_code, 500)
self.assertEqual(response.content, b'\\')
self.assertEqual(
p.mocks['get'].call_args_list[0][0], ('http://example.com',))
self.assertEqual(
p.mocks['post'].call_args_list[0][0], ('http://www.example.com',))
