pytest-skip-slow
A pytest plugin to skip `@pytest.mark.slow` tests by default.
Decision gist · record as of 2026-08-14
Yes. This is a lightweight, actively maintained plugin with no security issues, low install friction, and a clear, focused purpose. If your test suite includes slow or memory-intensive tests that you want to skip by default during development, it solves that problem with minimal overhead and no configuration required.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires pytest as a runtime dependency; Python 3.8 or later.
- Low friction: pure Python wheel with only pytest as a runtime dependency.
- Actively maintained with a recent release (79 days ago) and no known vulnerabilities.

What it is and what it does
pytest-skip-slow is a pytest plugin that automatically skips tests marked with `@pytest.mark.slow` or `@pytest.mark.hugemem` during normal test runs. This lets you maintain a comprehensive test suite without slowing down everyday development cycles—developers run the full suite only when explicitly requested via `--slow` or `--hugemem` flags, or in CI/CD pipelines where you want to catch all issues.
The plugin integrates directly into pytest's marker system, so you simply decorate slow or memory-intensive tests with the appropriate marker and the plugin handles the rest. It's a lightweight, zero-configuration addition to pytest that requires only pytest as a dependency and works with Python 3.8 and later.
Use it for
- Skip long-running integration or end-to-end tests during local development, running only fast unit tests by default.
- Exclude memory-intensive tests from CI pipelines that run on resource-constrained agents, enabling them only on dedicated hardware.
- Maintain a single test suite where developers can opt into slow tests with a single flag when debugging or validating a full test run.
- Separate performance or stress tests from the standard test flow without removing them from the codebase.
