0.17.0 blocks moto and httpretty interop

We have tests that utilize httpretty and moto but the 0.17.0 update causes the following error:

requests.exceptions.ConnectionError: Connection refused by Responses - the call doesn’t match any registered mock.

This is true because our internal calls are not an AWS destination and are mocked by httpretty.

Pinning back to 0.16.0 resolved the issue

@davetrollope Moto has just released a new version, 2.3.2.dev2, that works with all versions of responses. If you do run into any other issues with the latest version, feel free to raise them in Moto’s repo: https://github.com/spulec/moto/issues/4750

@beliaev-maksim Appreciate the offer! Looks like everything is sorted now. With 0.17.0, we no longer have to touch any of the internal API’s, so that always a good sign 🙂

On a janitorial note: It looks like ResponsesMock._matches is no longer used anywhere: https://github.com/getsentry/responses/blob/6e7d4669c1a0bb236747111fc8e9502c281d7fcf/responses/__init__.py#L524 If you want, I can raise a PR to remove this field?

Are you using an pass through prefixes to exclude responses from attempting to handle specific requests?

Moto maintainer here - yes, we do. This was our setup in 0.16:

responses_mock = responses.RequestsMock(assert_all_requests_are_fired=False)
responses_mock.add_passthru("http")

A reproducible usecase using Moto would be:

@moto.mock_sqs
def test_passthrough_requests():
    conn = boto3.client("sqs", region_name="us-west-1")
    conn.create_queue(QueueName="queue1")

    res = requests.get("https://httpbin.org/ip")
    assert res.status_code == 200

So the first request (hiding behind conn.create_queue() would be intercepted by responses, because our decorator has created a mock for it, but the second request should go through.
