swagger-stub

Swagger-stub create automatically a stub of your swagger REST API. This stub can be used anywhere you want like in a pytest fixture for your unit test.

In addition of mocking your API, you can mock some call, and check every call that have been made to the API.

Related Libraries

You may find related libraries to this one:

https://github.com/Trax-air/swagger-tester: Auto-test your swagger API in your unit tests. All test calls are generated by your swagger file.
https://github.com/Trax-air/swagger-aggregator: Aggregate several swagger specs into one. Useful for your API gateways!
https://github.com/Trax-air/swagger-parser: A helper that parses swagger specs. You can access the HTTP actions / paths and some example data

Example Usage

.. code:: python

import pytest import requests

from swagger_stub import swagger_stub

This is the fixture of your stub

You only need to specify the path of the swagger file and the address

where you want to bind your stub.

@pytest.fixture def test_stub(): return swagger_stub([('swagger.yaml', 'http://foo.com')]).next()

Then you can use this fixture anywhere you want like your API is really running.

def test_swagger_stub(test_stub):

Get a definition example

  test_stub.definitions['Foo']

  # Check a simple call
  response = requests.get('http://foo.com/v1/bar/')
  assert response.status_code == 200
  assert response.json() == {
    'foo': 'bar'
  }

  # Check that an invalid body cause an error
  response = requests.post('http://foo.com/v1/bar/', data='invalid data')
  assert response.status_code == 400

  # Mock a call
  test_stub.add_mock_call('get', '/test', {'mock': 'call'})
  response = requests.get('http://foo.com/v1/test')
  assert response.json() == {'mock': 'call'}

  # Set some side_effect like in the mock library
  test_stub.add_mock_side_effect('get', '/iter', [{'test': '1'}, {'test': '2'}, {'test': '3'}])
  response = requests.get('http://foo.com/v1/iter')
  assert response.json() == {'test': '1'}
  response = requests.get('http://foo.com/v1/iter')
  assert response.json() == {'test': '2'}
  response = requests.get('http://foo.com/v1/iter')
  assert response.json() == {'test': '3'}

  # This side effect will raise a custom error
  test_stub.add_mock_side_effect('get', '/error', Exception)

  with pytest.raises(Exception):
      response = requests.get('http://foo.com/v1/error')
