The script works well in local environments including PowerShell Core and Windows PowerShell

Suggested change

	if($null -ne $_.Since -and "Core" -eq $PSVersionTable.PSEdition) {
	if($PSVersionTable.PSVersion -lt [System.Version]$_.Since) {
	if($null -ne $_.Since -and "Core" -eq $PSVersionTable.PSEdition -and $PSVersionTable.PSVersion -lt [System.Version]$_.Since) {

Merged them into one line.

Suggested change

	Retry-AzCommand -Name $testName -Command $script -Retry $retry -Sleep $sleep
	$testInfo.PassedCount += 1
	Retry-AzCommand -Name $testName -Command $script -Retry $retry -Sleep $sleep
	$testInfo.PassedCount += 1

Add a space to keep same indent.

Updated the code. The problem indeed is indent of other lines is incorrect.
