pytest-metadata
pytest plugin for test session metadata
Decision gist · record as of 2026-08-14
Yes. This is a stable, actively maintained plugin in the top 1000 PyPI packages with no known vulnerabilities. It has minimal dependencies (pytest only) and low install friction. It's essential if you need to capture, display, or act on test session environment metadata—particularly valuable in CI/CD pipelines and for generating reproducible test reports.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later, or PyPy3.
- Low friction: pure Python wheel with only pytest as a runtime dependency.

What it is and what it does
pytest-metadata is a pytest plugin that automatically gathers and makes available metadata about your test session. It collects standard information like the Python version, operating system platform, installed pytest packages, and active plugins. When running in a continuous integration environment (AppVeyor, Bitbucket, CircleCI, GitLab CI, Jenkins, TaskCluster, or Travis CI), it also extracts relevant CI environment variables and includes them in the metadata.
You can access this metadata in multiple ways: through a pytest fixture named `metadata` in your tests, via a hook function `pytest_metadata` to modify or filter the data, through the config stash in plugins, or displayed in test reports when using `--verbose`. You can also add custom metadata via command-line flags (`--metadata`, `--metadata-from-json`, `--metadata-from-json-file`) or include it in JUnit XML output using the `include_metadata_in_junit_xml` fixture.
Use it for
- Display test environment details in verbose test output to verify which Python version and platform a test suite ran on.
- Embed CI build information (branch, commit, build ID) into JUnit XML reports for traceability.
- Access platform and package versions from within a test to skip or adapt behavior based on environment.
- Integrate with HTML report plugins like pytest-html to show environment context at the start of reports.
- Filter sensitive metadata (e.g., passwords) before reports are generated using the pytest_metadata hook.
