betamax 0.1.2

A VCR imitation for python-requests

betamax

Betamax is a VCR imitation for requests. This will make mocking out requests much easier. Tested on Travis CI.

Example Use

from betamax import Betamax
from requests import Session
from unittest import TestCase

with Betamax.configure() as config:
    config.cassette_library_dir = 'tests/fixtures/cassettes'


class TestGitHubAPI(TestCase):
    def setUp(self):
        self.session = Session()
        self.headers.update(...)

    # Set the cassette in a line other than the context declaration
    def test_user(self):
        with Betamax(self.session) as vcr:
            vcr.use_cassette('user')
            resp = self.session.get('https://api.github.com/user',
                                    auth=('user', 'pass'))
            assert resp.json()['login'] is not None

    # Set the cassette in line with the context declaration
    def test_repo(self):
        with Betamax(self.session).use_cassette('repo') as vcr:
            resp = self.session.get(
                'https://api.github.com/repos/sigmavirus24/github3.py'
                )
            assert resp.json()['owner'] != {}

VCR Cassette Compatiblity

Betamax can use any VCR-recorded cassette as of this point in time. The only caveat is that python-requests returns a URL on each response. VCR does not store that in a cassette now but we will. Any VCR-recorded cassette used to playback a response will unfortunately not have a URL attribute on responses that are returned. This is a minor annoyance but not something that can be fixed.
