in some environments, like building packages for Linux distributions, external network connections are not allowed right now, python-future has two tests that perform network connections: - `tests/test_future/test_standard_library.py::TestStandardLibraryReorganization::test_moves_urllib_request_http` - `tests/test_future/test_standard_library.py::TestStandardLibraryReorganization::test_urllib_request_http` it would be nice to provide an easy way to disable those tests, e.g. with an environmental variable ( see https://github.com/pypa/distlib/blob/32301789a7815de0e74f57fe013ae52af717a3da/tests/test_index.py#L343 )
