#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for firewall IP set cmdlets:
        Get-PveFirewallIpSet, New-PveFirewallIpSet, Remove-PveFirewallIpSet,
        Get-PveFirewallIpSetEntry, New-PveFirewallIpSetEntry, Set-PveFirewallIpSetEntry,
        Remove-PveFirewallIpSetEntry.

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