I was looking into taking a script block and running this in a infinite loop in Windows Powershell in order to perform testing of a particular action over a sustained period of time.
I was able to do this while using the calling the While expression with a true value, which will perform an endless loop during the powershell session.
While($true)
{
$i++
<action to invoke>
Write-Host "Action has run $i times"
}
