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

Issue Tracker Tickets (Jira or BZ if any): linux-system-roles/postfix#206 https://redhat.atlassian.net/browse/RHELMISC-16008

Notes: I included a separate assertion file since Ansible's loop: can only wrap a single task/include

Summary by CodeRabbit

  • New Features

    • Added validation for network role parameters and connection settings.
    • Added checks for IP addresses, routes, routing rules, Ethernet, VLAN, wireless, and other network options.
    • Validation now provides clearer details about supported connection properties and accepted values.
  • Bug Fixes

    • Invalid network configurations are detected before changes are applied, reducing the risk of partial updates.
  • Tests

    • Added integration coverage for valid defaults and invalid parameter scenarios.

📝 Walkthrough

Walkthrough

The role adds argument specifications for network inputs, validates raw IP fields before provider processing, and adds integration tests for argument, role, and module validation failures.

Changes

Network input validation

Layer / File(s) Summary
Argument specifications
meta/argument_specs.yml
Adds specifications for connection profiles, nested network settings, defaults, choices, exclusions, and top-level role parameters.
Early role validation
tasks/main.yml, tasks/assert_role_vars.yml, tasks/assert_connection_vars.yml
Runs per-connection assertions before network provider processing. The assertions normalize scalar raw fields and validate IP address, route, and routing-rule values.
Invalid-input integration tests
tests/tests_invalid_input.yml
Tests argument specification, role assertion, and module runtime failures, with cleanup of collected facts.

Suggested reviewers: richm

Merge Risk: 🟡 Moderate · up to ada3a

Resolve the validation-test and scalar-input concerns before merging: the tests may report a successful rejection for the wrong failure, while some malformed inputs may produce a loop error rather than the intended validation message.

Does it make sense to repeat the description here instead of saying "same format as ..."? Would make it more readable
