233-247: Stop after error and fix TargetObject; make count robust
- After Write-Error, return to avoid continuing to rename. As per guidelines: “always return after Write-Error.”
- Replace undefined $ServiceType with a meaningful target (e.g., $DestinationPath).
- Make count robust; optionally use Get-ChildItem.
Apply:
- # Get all the iso files in the destination path and if there are more than one throw an error. - $isoFile = Get-Item -Path "$DestinationPath/*.iso" -Force - - if ($isoFile.Count -gt 1) + # Get all ISO files in the destination path; error if more than one + $isoFile = Get-ChildItem -Path $DestinationPath -Filter '*.iso' -File -Force + + if (@($isoFile).Count -gt 1) { $writeErrorParameters = @{ Message = $script:localizedData.SqlServerMediaFile_Save_MultipleFilesFoundAfterDownload Category = 'InvalidOperation' ErrorId = 'SSDSSM0002' # CSpell: disable-line - TargetObject = $ServiceType + TargetObject = $DestinationPath } Write-Error @writeErrorParameters + return } Write-Verbose -Message ($script:localizedData.SqlServerMediaFile_Save_RenamingFile -f $isoFile.Name, $FileName) # Rename the iso file in the destination path.

203-224: Add tests to cover -Force with non-target ISOs and .exe pathCurrent tests don’t cover:
- -Force when exactly one different ISO exists (expected: allow if aligning with PR objective).
- Same scenarios when URL is an .exe (download+extract flow).
Recommend adding:
- One test asserting no throw and overwrite when one non-target ISO exists and -Force is used; throw only when >1 non-target ISOs exist.
- Mirror both for .exe URLs.
Also applies to: 226-255
