What pytest-ansible is

pytest-ansible is a free pytest plugin for using Ansible in tests, including unit testing for Ansible collections. Its pytest-ansible-units component runs collection unit tests and tests individual modules in isolation. Legacy fixtures such as ansible_module, ansible_adhoc, localhost, and ansible_facts let tests call modules, work with inventory, and access system facts. The project runs locally and is aimed at collection authors and developers writing pytest tests with Ansible. Installation uses pip install pytest-ansible. Supported versions are Python 3.10 or newer and ansible-core 2.14 or newer. The documented ecosystem includes pytest, Ansible, Ansible collections, and a deprecated Molecule integration. That integration does not support Molecule shared_state or --workers. Migration guidance recommends ADE with plain pytest for collection unit tests, tox-ansible for collection CI, and the Molecule CLI for scenarios. The project is deprecated, with planned end of life in December 2026. It is MIT-licensed, and issues should be reported on GitHub.

Who it suits

It is intended for Ansible collection authors and developers who want Ansible modules, inventory, or collection tests inside pytest. Teams starting new work should account for its deprecation and migration guidance.

What it does well

  • Free and MIT licensed
  • Runs Ansible collection unit tests
  • Tests individual modules in isolation
  • Provides Ansible pytest fixtures
  • Local execution model

What to know first

  • Deprecated project
  • Planned end of life in December 2026
  • Molecule integration is deprecated
  • No Molecule shared_state or workers support

Getting started

  1. Open the pytest-ansible GitHub website
  2. Use Python 3.10 or newer with ansible-core 2.14 or newer
  3. Install the package with pip install pytest-ansible
  4. Configure pytest tests with Ansible or collection fixtures as needed

Verdict

pytest-ansible can connect existing pytest workflows with Ansible collection tests and fixtures. Its deprecation makes the recommended ADE, tox-ansible, and Molecule alternatives important for future planning.
