Enhancement: Added argument spec and assert role spec validation to the storage 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.

    • Added supported-value restrictions for storage providers and RAID levels.
    • Added type checks for sizes, cache sizes, disk labels, and partition settings.
  • Bug Fixes

    • Invalid or unsupported storage configurations are now rejected before changes begin.
    • Validation errors identify the affected setting and received value.

Changes

Storage input validation

Layer / File(s) Summary
Define role argument specifications
meta/argument_specs.yml
The role defines schemas and defaults for storage providers, volumes, pools, and related options. It restricts provider and RAID-level choices and documents partition and RAID settings.
Run runtime variable assertions
tasks/assert_role_vars.yml, tasks/main.yml
The role validates partition settings, disk label types, and volume and pool volume size fields before provider tasks run. Integer sizes and cache sizes must be non-negative.
Verify rejected inputs
tests/tests_invalid_input.yml
The playbook checks argument specification errors and runtime assertion failures for invalid types, choices, missing names, boolean sizes, and negative integer sizes or cache sizes.

Merge Risk: ⚪ Minimal · up to 64dc5

The PR adds storage-role argument validation and rejection tests without introducing an actionable merge-blocking risk; it is merge-ready after normal checks and review.

In `@meta/argument_specs.yml`:
- Line 422: Update the storage_volume_defaults argument specification around
size so the nested dict values are validated before provider execution: add the
appropriate nested options for storage_volume_defaults.size and matching
assertions, preserving the existing type and validation conventions used by
nearby argument specifications.
- Line 12: Add choices validation for storage_provider so only blivet is
accepted, and constrain the volume raid_level option to the documented supported
RAID levels. Update the related invalid-input tests to cover unsupported
provider and RAID values while preserving valid configurations.

In `@tests/tests_invalid_input.yml`:
- Around line 12-13: Replace every direct ansible.builtin.include_role
invocation in the invalid-input tests with ansible.builtin.include_tasks
referencing tasks/run_role_with_clear_facts.yml, preserving each case’s existing
role variables and inputs so all cases run through the required fact-isolation
wrapper.
- Around line 30-32: Update the rescue handlers for the invalid
storage_safe_mode type rejection tests to set their success facts only when
ansible_failed_result identifies the expected argument-spec or assert_role_vars
validation failure. Preserve the existing failure assertion behavior and follow
the validation-error gating used by the missing-name cases.

I think the condition should be something like this:

(item.size is string and (item.size == "0" or item.size is match(...))
or ((item.size | type_debug) == "int" and item.size >= 0)

You shouldn't need the | int because you have already determined that the value is type int
