Describe the Problem

Throws warnings and quite likely does not work properly with Pester v5.0 Pester v5.0 changed from command line switches, hashtables, etc. to a single Configuration nested hashtable object.

Steps To Reproduce

1. Import-Module Pester -RequiredVersion 5.0.4
2. Run Invoke-PSCodeHealth -Path .\src -TestsPath .\tests
3. Error or unexpected behavior :

WARNING: You are using Legacy parameter set that adapts Pester 5 syntax to Pester 4 syntax. This parameter set is
deprecated, and does not work 100%. The -Strict and -PesterOption parameters are ignored, and providing advanced
configuration to -Path (-Script), and -CodeCoverage via a hash table does not work. Please refer to
https://github.com/pester/Pester/releases/tag/5.0.1#legacy-parameter-set for more information.

Expected behavior

PSCodeHealth should detect the Pester version and invoke the command properly.

Environment

• Operating system : Windows10
• PowerShell version : 5.1.18362.1110
• PSCodeHealth version : 0.2.26

You can also provide a -TestResult to Invoke-PSCodeHealth. So run your Pester 5 tests with -PassThru and then pipe that into ConvertTo-Pester4Result. You do have to manage the currently imported version of Pester though.

Import-Module Pester -MinimumVersion 5.0.0
$configuration              = [PesterConfiguration]::Default
$configuration.Run.Path     = $TestPath
$configuration.Run.PassThru = $true
$testResult = Invoke-Pester -Configuration $configuration | ConvertTo-Pester4Result

Remove-Module Pester -Force
Import-Module Pester -MaximumVersion 4.*

Invoke-PSCodeHealth -Path $CodePath -TestsResult $testResult
