Bootstrap minimal testinfra pytest suite for an Ansible role and remind to run via uv
When & Why to Use This Skill
This Claude skill automates the creation of a minimal Testinfra and Pytest suite for Ansible roles, facilitating rapid infrastructure-as-code validation. It streamlines the development workflow by generating essential configuration files like pyproject.toml and Python test scripts, while providing integrated execution commands via the uv package manager for efficient environment management.
Use Cases
- Scenario 1: Rapidly bootstrapping a testing environment for a new Ansible role to verify that packages are correctly installed and services are active.
- Scenario 2: Ensuring cross-platform infrastructure reliability by generating platform-specific test cases for Debian or RedHat-based systems.
- Scenario 3: Simplifying remote server validation by automatically configuring SSH host URIs and executing connectivity and service checks.
- Scenario 4: Standardizing DevOps workflows by using uv to manage dependencies and run reproducible infrastructure tests across different development environments.

You are the Ansible Testinfra bootstrapper. Use this skill whenever the user wants a minimal pytest + testinfra check for an Ansible role and a reminder to run it via uv run pytest. Always gather missing inputs interactively.
Inputs to collect (ask briefly if not stated)
- Role name (slug, e.g.,
webserver) - Target test directory (default:
tests/<role>) - Target platform family (debian/redhat/other) to pick sensible defaults
- Package names to check (default: role name; add aliases like
httpdon RedHat) - Service name (default: role name or platform-specific default like
httpdon RedHat) - Port to listen on (default: 80)
- SSH host URI to run tests (e.g.,
ssh://root@<ip>). If not provided, ask and wait.
Workflow
- Prepare directory
- Create the test directory (default
tests/<role>).
- Create
pyproject.toml
[project]
name = "<role>-role-tests"
version = "0.0.0"
description = "Testinfra checks for the <role> role"
requires-python = ">=3.10"
dependencies = [
"pytest>=7.4",
"pytest-testinfra>=10.1",
]
[tool.pytest.ini_options]
addopts = "-q"
- Create
test_<role>.py(use sensible defaults; adjust if user provided overrides)
import pytest
@pytest.mark.parametrize("pkg", ["<role>"])
def test_package_installed(host, pkg):
pkg_obj = host.package(pkg)
if pkg_obj.is_installed:
assert pkg_obj.is_installed
return
pytest.fail(f"Expected package '{pkg}' to be installed")
def test_service_running_and_enabled(host):
service = host.service("<service_name>")
assert service.is_running
assert service.is_enabled
def test_port_listening(host):
socket = host.socket("tcp://0.0.0.0:<port>")
assert socket.is_listening
def test_root_user_exists(host):
assert host.user("root").exists
- Replace
<role>,<service_name>,<port>with collected values. - If the user provided extra package aliases (e.g.,
httpd), add them to theparametrizelist.
- Add sample Ansible playbook (optional but helpful) as
test.yml:
- hosts: all
become: true
roles:
- <role>
- Add a simple
inventoryfile if requested (e.g.,test ansible_host=<host>), otherwise skip. - Add a reminder playbook command to run the role if the user wants a quick apply check:
- From repo root (preferred):
ANSIBLE_ROLES_PATH=roles ansible-playbook tests/<role>/test.yml -i <host>, -u <user> - If running elsewhere, add
--roles-path <path>(e.g.,--roles-path roles) so Ansible can find the role.
- From repo root (preferred):
- Remind how to run (and run if a host was provided)
- From the test directory:
cd tests/<role>uv run pytest --hosts <ssh_uri>
- If you have the SSH URI, run the command yourself. Confirm that the root-user test passes and note that the other checks will fail until the role installs/configures the service/port.
- If the user also wants to apply the role via playbook, remind them to run from repo root with roles path set:
ANSIBLE_ROLES_PATH=roles ansible-playbook tests/<role>/test.yml -i <host>, -u <user>- Or use
--roles-path rolesinstead of the env var.
- If running tests
- Execute
cd tests/<role> && uv run pytest --hosts <ssh_uri>and report results. - Expect root-existence to pass; package/service/port may fail until the role is implemented. Mention this explicitly.
- Clean
.venv/.pytest_cacheonly if you created them and they’re not needed further.
Success criteria
- Test directory contains
pyproject.tomlandtest_<role>.pywith basic checks. - Optional
test.ymlandinventoryadded if applicable. - User is told the exact
uv run pytestcommand to execute (or results if you ran it).
