[PYTHON] Mock HTTP requests via the requests module in Responses

Reponses is a library that mock the requests module that performs HTTP communication. Made by Dropbox that seems to be reliable. The license is APL 2.0.

class APITestCase(TestCase):
    @responses.activate
    def test_api(self):
        import api

        # setup
        responses.add(
            responses.GET,
            'https://example.com/api/v3/users',
            status=200,
            body="[{'user': {'id': 1, 'username': 'test'}}]",
            content_type="application/json",
        )

        # test
        api.get_users()
        assert responses.calls[0].request.method == 'GET'
        assert responses.calls[0].request.url == 'https://example.com/api/v3/users'

There is also httpretty because it is similar, but Responses was more suitable for me. I will try it for a while.

• I think the Responses interface is influenced by httpretty.
