RuntimeError: HTTPretty intercepted and unexpected socket method call. (amqp/pika/rabbitmq)

[aaltepet]

httpretty instructed me to report a bug.

Try this simple script:

import pika
import httpretty

@httpretty.activate
def test_me():
        parameters = pika.URLParameters('amqp://guest:guest@localhost:5672/%2F')
        connection = pika.BlockingConnection(parameters)
        channel = connection.channel()
        channel.exchange_declare(exchange='e', durable=True, type='direct')
        channel.queue_declare(queue='q', durable=True, exclusive=False,
                              auto_delete=False)
        channel.queue_bind(exchange='e', queue='q', routing_key='q')
        channel.close()
        connection.close()

test_me()

returns the following traceback:

I get the same message (although different stacktrace) with cymysql.
