#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for storage management cmdlets:
        Set-PveStorage, Get-PveStorageStatus, Remove-PveStorageContent,
        Set-PveStorageContent, New-PveStorageDisk.

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