I am trying to mock a get request with requests_mock, but it doesn't seem to get it right.

My function calling a third-party API defined in a file lookup.py:

from botocore.vendored import requests



def get_data():

   url = 'https://abc.something.com/datapackage'

   url_params={

      'v': 2,

      'auth_apikey':'xyz'

   }

   resp = requests.get(url, params=url_params)

   return resp.json()

I am using py.test to run my tests and in my test file. I have a fixture:

  import requests_mock

  import requests, pytest

  from lookup import get_data



  @pytest.fixture

  def req_mock(request):

    m = requests_mock.Mocker()

    m.start()

    request.addfinalizer(m.stop)

    return m



  def test_api_gets_data(req_mock):

      sample={

          'key1':123

      }

      lookup_url = 'https://abc.something.com/datapackage'

      query_params = {

        'v': 2,

        'auth_apikey':'xyz'

      }

      req_mock.get(lookup_url, json=sample)

      resp = get_data()

Apparently, requests_mock isn't able to use the same session as the requests in the get function, so it isn't getting mocked.

Is there a better way to do this?

I'm using Python 3.6, requests 2.18, requests-mock 1.52 and pytest 3.0.7.

at lookup.py files, lookup_url will raise NameError cause name lookup_url not defined.

use url and don't forget to change params=url_params, so the code will be something like this:

resp = requests.get(url, params=url_params)

Apparently you can't mock from botocore.vendored import requests with requests_mock.

Instead use unittest.mock to mock the response.

  from unittest import mock



  class MockResponse:

    def __init__(self, status_code, json_data=None):

      self.json_data = json_data

      self.status_code = status_code



   def json(self):

      return self.json_data



   def raise_for_status(self):

      if self.status_code >= 500:

        raise Exception



 item_not_found = {

    "Response": {

      "StatusCode": "ItemNotFound",

    }

 }



 item_not_found_resp = MockResponse(200, item_not_found)





 @mock.patch('botocore.vendored.requests.get', return_value=item_not_found_resp)

 def test_api_returns_not_found_when_third_party_api_returns_item_not_found(mc):

     resp = get(e1, c)

     exp_resp = {

       "statusCode": 404,

       "body": json.dumps({

        'error': 'no item found'

       })

     }

   request_url = mc.call_args[0][0]

   request_params = mc.call_args[1]['params']

   assert lookup_url == request_url

   assert query_params == request_params

   assert exp_resp == resp
