ansible-testinfra

Testinfra validates infrastructure by writing pytest tests that check packages, services, ports, and other system state on remote hosts. This Skill bootstraps a minimal pytest + testinfra suite with a test directory, pyproject.toml, and starter test file ready to run against your Ansible role.

You need Python 3.10+, an Ansible role, and pytest with the testinfra plugin installed. This Skill creates the project structure and dependency configuration (pyproject.toml) so you can immediately run tests via uv run pytest against your infrastructure.

Yes. Testinfra runs pytest tests against live systems over SSH to verify packages, services, ports, and configuration are correct after Ansible applies changes. This Skill generates a ready-to-run test suite that connects to your target hosts and validates the deployment.

Execute uv run pytest --hosts ssh://<host> to run your test suite against a remote system. This Skill provides the starter tests and project configuration; you specify the SSH host URI and the tests execute validation checks on that infrastructure.

A starter Testinfra test verifies that required packages are installed, a service is running, and it listens on the expected port. This Skill generates a template test_<role>.py that checks these common validation points; you extend it with additional assertions as needed.

Basic pytest knowledge is helpful but not required. This Skill generates a starter test file with pytest + testinfra patterns already in place, and provides reminders on how to execute tests, so you can begin validating infrastructure immediately and learn patterns from the generated code.
