It works by globally disabling socket access or by restricting connections to an allowlist of specific hosts, IP addresses, or CIDR ranges. You can apply these restrictions via CLI flags (like `--disable-socket`), pytest configuration files, or per-test via fixtures and markers.\n\nThe plugin is useful for ensuring tests remain isolated and deterministic by catching accidental or unintended network dependencies. It supports selective allowlisting, Unix domain socket access for async testing, and per-test overrides. The plugin has been actively maintained since 2017 and supports Python 3.10 through 3.14.","worth_installing":"Yes. This is a focused, well-maintained tool with low install friction and no security issues. It solves a real problem\u2014preventing accidental network calls in tests\u2014and integrates cleanly with pytest via CLI flags, config, or fixtures. The MIT license is permissive and the active maintenance (recent release, active repo) makes it reliable for production test suites."},"id":"pytest-socket","links":{"html":"https://skillfed.io/packages/pytest-socket","md":"https://skillfed.io/packages/pytest-socket.md","pypi":"https://pypi.org/project/pytest-socket/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-21","license_spdx":"MIT","license_treatment":"permissive","name":"pytest-socket","python_support":"supports_current","summary":"Pytest Plugin to disable socket calls during tests"},"popularity":{"monthly_downloads":13881633,"position":1260,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.8.0"}
