Publishing results in NUnit tests - powershell

Question

I am writing a PowerShell script for multithreading NUnit tests. My problem is that I take test categories from the file category.txt, and I have to write which categories have been done into my output file file 1.txt. I also need to output an XML report after all tests have been performed. How can I do this in NUnit?
$Groups=Get-Content d:\test\category.txt | Select-Object -Last 10
Write-Host $Groups
if ($Groups -ne $null)
{Write-Host "true"}
else
{write-host "false"}
###Multithreading###
$ThreadNumber =$Groups.Count
$ScriptBlock = {
function Nunit {
$Connection = #{"server" = ""; "username" = ""; "password" = ""}
write-verbose $Connection
$serv = $connection.Get_Item("server")
$user = $connection.Get_Item("username")
$pass = $connection.Get_Item("password")
$securePassword = ConvertTo-SecureString -AsPlainText $pass -Force
#Create connection credentials object for Invoke-Command
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $user, $securePassword
$Output = "C:\"
$scriptBlock = {
CMD.EXE /C "C:\testNunit\bin\nunit-console.exe /xml:c:\console-test.xml C:\testNunit\dll\Tests.dll /include:TestTypeSmoke> c:\1.txt"
}
Invoke-Command -ComputerName $serv -ScriptBlock $scriptBlock -credential $cred
}
Nunit
}

I will try to get back to you on NUnit after trying some things at my end, but as a suggestion you could also try PowerShell Workflow for Multi-Threading. They work like functions.
Workflow NUnit
{
Param
(
$server,
$username,
$password,
)
foreach -parallel -throttlelimit 2($group in $groups)
try{
//NUnit Code here
}
}
Catch
{
$_.Exception.Message
}
}
}
NUnit-server "" -username "" -password ""
