#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for firewall alias cmdlets:
        Get-PveFirewallAlias, New-PveFirewallAlias, Set-PveFirewallAlias, Remove-PveFirewallAlias.

    All tests are fully offline — no live Proxmox VE target is required.
    If a cmdlet is not yet compiled the test is marked Skipped.
