#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for container gap cmdlets:
        Suspend-PveContainer, Resume-PveContainer, Resize-PveContainerDisk,
        New-PveContainerTemplate, Move-PveContainerVolume, Get-PveContainerInterface.

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