⚙️ [Maintenance]: Hard-lock Pester test dependency to 5.8.0 by GUID

[Marius Storhaug (MariusStorhaug)]

Hard-locks the Pester test dependency to an exact version pinned by module GUID, replacing the RequiredVersion = '5.7.1' pin that broke test discovery when the runner installed Pester 5.8.0.

#Requires -Modules @{ ModuleName = 'Pester'; RequiredVersion = '5.8.0'; GUID = 'a699dea5-2c73-4616-a270-1f7abb777e71' }

Why 5.8.0 + GUID

• Exact version = reproducible and supply-chain-safe (no silent drift to a newer or compromised release).
• GUID pins module identity (anti-name-squat). Both the version and the GUID are enforced by PowerShell at discovery time (verified locally).
• No version comment — unlike a GitHub Actions @<sha>, RequiredVersion already states the version in plain text, and #Requires rejects a GUID without a version key.

Files updated: 17 test file(s).

Fixes #636.

Note

This pin fully holds once Invoke-Pester installs the pinned version instead of the latest (today it installs newest, so a future Pester release would re-break exact pins). Tracked in PSModule/Invoke-Pester#68. Part of the dependency-management epic PSModule/Process-PSModule#356.

Changes:

• Replace #Requires pins from Pester 5.7.1 to 5.8.0 across all affected test files.
• Add the Pester module GUID to the #Requires -Modules specification to enforce module identity at discovery time.
