#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for SDN Set cmdlets and related mutating cmdlets:
        Set-PveSdnZone, Set-PveSdnVnet, Set-PveSdnSubnet, Set-PveSdnController,
        Set-PveSdnIpam, Set-PveSdnDns, Invoke-PveSdnApply, Set-PveRole, Set-PveApiToken.

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