PyTest Molecule Plugin :: discover and run molecule tests
PyTest Molecule Plugin :: auto detects and runs molecule tests
This plugin enables pytest discovery of all molecule.yml files inside the codebase and runs them as pytest tests.
Once you install pytest-molecule you should be able to just run pytest in order to run molecule on all roles and scenarios.
Optionally you can define MOLECULE_OPTS for passing extra parameters to each molecule call.
Discovered tests do have molecule driver and platforms added as markers, so you can selectively limit which test types to run:
# Lists all tests that uses docker $ pytest --collect-only -m docker # Runs scenarios with platform named centos7 and delegated driver: $ pytest -m delegated -m centos7
If the molecule scenario does not contain information about the driver, the test associated with it gets a no_driver mark.
Please note that at this moment molecule will run the entire scenario if the markers are platforms, this is not yet a way to limit which platforms are executed inside a specific scenario.
All tests are added the molecule marker.
This plugin also adds a new pytest option named --molecule-unavailable-driver=skip which can be used to tell it what to do when molecule drivers are not loading. Current default is None but you can choose marks like skip or xfail.
$ PIP_NO_BUILD_ISOLATION=false pip install pytest-molecule
PIP_NO_BUILD_ISOLATION is needed only on ancient python distributions to workaround https://github.com/pypa/pip/issues/5229
Contributions are very welcome. Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.
