Ansible Testinfra

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 httpd on RedHat)
• Service name (default: role name or platform-specific default like httpd on 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

1. Prepare directory

• Create the test directory (default tests/<role>).

1. 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"

1. 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 the parametrize list.

1. Add sample Ansible playbook (optional but helpful) as test.yml:

- hosts: all
  become: true
  roles:
    - <role>

• Add a simple inventory file 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.

1. 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 roles instead of the env var.

1. 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_cache only if you created them and they’re not needed further.

Success criteria

• Test directory contains pyproject.toml and test_<role>.py with basic checks.
• Optional test.yml and inventory added if applicable.
• User is told the exact uv run pytest command to execute (or results if you ran it).
