httpretty.errors.UnmockedError: Failed to socket.setblocking because because a real socket does not exist

[AltafHussain4748]

I am using moto a python library to mock aws services. On my local everything works fine but on teamcity I get the error

httpretty.errors.UnmockedError: Failed to socket.setblocking because because a real socket does not exist

I am usning httpretty==1.1.4 with python3.8.

Hi @AltafHussain4748, which version of Moto are you using?

Can you also share an example test case that throws this error, and a full stacktrace?

Closing this - there's not much we can do without something reproducible.

Hi ,
I'm also facing same error. When there is env variable http_proxy/https_proxy, this error is shown as following. Once I remove http_proxy/https_proxy, there is no error and complete with success for testing.

I tested with this simple examples as following,

sample_httpretty
|-- sample_httpretty
| |-- init.py
| |-- get_something.py
|-- tests
| |-- init.py
| |-- test_something.py
|-- pytest.ini

# sample_httpretty/get_something.py
import requests


class getSomething(object):
    def get_something(self):
        url = "https://httpbin.org/get"
        r = requests.get(url)
        return r

# tests/test_something.py
import json
import unittest

import httpretty

from sample_httpretty.get_something import getSomething


class testGetSomething(unittest.TestCase):
    def test_get_something(self):
        res_test = {
            "args": {},
            "headers": {

        }
        httpretty.enable(allow_net_connect=False)
        httpretty.register_uri(
            httpretty.GET,
            "https://httpbin.org/get",
            body=json.dumps(res_test),
            content_type="application/json",
        )
        res = getSomething().get_something()
        print(res.text)

This looks same as #122
