⚙️ [Maintenance]: Require Pester 6.x in test files

[Marius Storhaug (MariusStorhaug)]

Pester tests in this module now require the Pester 6.x major version, so every contributor and CI run resolves the same major and a new Pester major can't slip in and break the suite. The tests previously declared no framework requirement and ran on whatever Pester happened to be installed.

Changed: tests are locked to the Pester 6.x major

Every *.Tests.ps1 file now starts with a version-bounded requirement:

#Requires -Modules @{ ModuleName = 'Pester'; ModuleVersion = '6.0.0'; MaximumVersion = '6.*' }

Any Pester 6.x satisfies it, so minor and patch releases flow in automatically while moving to a new major stays a deliberate, reviewed change. No module source or behaviour changes.

Technical Details

• Prepends a #Requires -Modules statement to each test file under tests/; non-test files are untouched.
• ModuleVersion = '6.0.0' is the floor and MaximumVersion = '6.*' the wildcard major ceiling. Module-identity (GUID) pinning is intentionally omitted — it is a separate supply-chain control, not part of the lock-to-major risk appetite.
• The install side is locked to the same major in ⚙️ [Maintenance]: Lock Pester to the 6.x major version Invoke-Pester#70. Part of the dependency-management epic Dependency management for PowerShell scripts and modules Process-PSModule#356.

Pull request overview

This PR aims to enforce a Pester 6.x dependency for the module’s test scripts by adding a #Requires -Modules module specification at the top of each test file, so tests fail early if the required Pester major version isn’t available.

Changes:

• Added #Requires -Modules for Pester to tests/PSModuleTest.Tests.ps1.
• Added #Requires -Modules for Pester to tests/Environment.Tests.ps1.
