Enhancement: Added argument spec and assert role spec validation to the crypto policies role. Also wrote tests for it found in tests/tests_invalid_input.

Reason: Because it is a good addition to the linux-system-roles project.

Result: Successfully added it and prepared tests for it. I used AI during this implementation.

Summary by CodeRabbit

  • New Features

    • Added documented configuration options for selecting crypto policies, reloading services, regenerating policies, and allowing standard or transactional-update reboots.
    • Added validation for policy and reboot-related settings, with clear errors when values use unsupported types.
  • Tests

    • Added coverage confirming valid defaults are accepted and invalid configuration values are rejected across supported input formats.

Review Change Stack

📝 Walkthrough

Walkthrough

The role now defines argument specifications, validates selected variable types before setup, and tests invalid boolean, policy, and transactional-update reboot inputs.

Changes

Crypto policies parameter validation

Layer / File(s) Summary
Argument specification contract
meta/argument_specs.yml
Defines five role options with types, defaults, descriptions, accepted policy formats, and reboot behavior.
Runtime variable validation
tasks/main.yml, tasks/assert_role_vars.yml
Runs parameter validation before platform setup. Validates policy and transactional-update reboot variable types.
Invalid-input test coverage
tests/tests_invalid_input.yml
Tests valid defaults, argument-specification failures, variable-type failures, rejection facts, and cleanup.

Merge Risk: 🔵 Low · up to 6ea3a

The PR adds argument validation to the role, but some invalid-input tests can produce false-positive results because they do not isolate role facts and do not verify the specific expected failure. The change is otherwise localized and mergeable with explicit owner awareness or follow-up on test correctness.

12-13: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Use the managed wrapper for every role invocation.

Replace each direct ansible.builtin.include_role call with ansible.builtin.include_tasks: tasks/run_role_with_clear_facts.yml. Preserve each existing crypto_policies_* variable under vars.

As per path instructions, “NEVER use ansible.builtin.include_role directly” and “ALWAYS use the centrally managed wrapper.”

Proposed replacement
-          ansible.builtin.include_role:
-            name: linux-system-roles.crypto_policies
+          ansible.builtin.include_tasks: tasks/run_role_with_clear_facts.yml

Assert the valid-defaults result.

The success case only checks that the role completes. Add an ansible.builtin.assert task for the expected role fact or state after the wrapper returns.

As per path instructions, “Tests should verify both success and failure scenarios” and “Use assert module to verify expected state after role execution.”

Validate the rescued failure before setting the rejection marker.

Each rescue block marks the input as rejected for any include_role failure. Check ansible_failed_result for the expected variable and invalid type before setting the marker. Otherwise, an unrelated role failure can make the test pass incorrectly.

Update the section label to Ansible 2.11+.

The heading says Ansible 2.10+, but the block runs only when ansible_version.full is at least 2.11. Keep the test documentation consistent with the executable condition.
