#Requires -Modules Pester <# .SYNOPSIS Unit Tests fuer Invoke-sqmHealthReport. Alle aufgerufenen Teilfunktionen und Invoke-DbaQuery werden gemockt - getestet wird die Orchestrierung: Abschnittsauswahl, Befund-Sammlung und -Sortierung, Fehlertoleranz je Abschnitt, Messfenster-Reihenfolge, Abbruch bei unerreichbarer Instanz. Die echten Abfragen sind live gegen SQL Server 2025 geprueft. #> BeforeAll { .
