#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for HA (High Availability) cmdlets:
        Get-PveHaResource, New-PveHaResource, Set-PveHaResource,
        Remove-PveHaResource, Move-PveHaResource,
        Get-PveHaGroup, New-PveHaGroup, Set-PveHaGroup, Remove-PveHaGroup,
        Get-PveHaStatus,
        Get-PveHaRule, New-PveHaRule, Set-PveHaRule, Remove-PveHaRule.

    All tests are fully offline — no live Proxmox VE target is required.
