More AutoTesting - Powershell extensions and addins

There is a nice library called PS-Eventing that makes the event handling a whole lot cleaner and generally a nicer experience. This post with the plugin is not a smaller and doesnt really do any else other than the last post except cleanly deregister the event, but is much more user friendly.
I think i will also post my code on gisthub as I am not and have not been at my real machine for so long... i miss it... sorry.
Heres the link :

Auto test - Thanks Powershell

Im doing some funky Nunit stuff* at the moment and sometimes the ReSharper or TD.Net runner wont pick up my inner fixtures, the console runner however runs them just fine. Here is a PS script to have auto test running on build:

$Script:initialdir = "C:\myroot\"

$fsw = new-object
$fsw.Path = "c:\mysln\myproj\Bin\"
$fsw.EnableRaisingEvents = $true

$action = {
$filter = "*Tests*.dll"
$file = $Event.SourceEventArgs.FullPath
if($file -like $filter)
$nunit = "C:\3rdParty\NUnit-2.5.2\nunit-console"
$currentdate = get-date -format g
write-Host "Running Tests on $file $currentdate" -ForegroundColor Yellow
&"$nunit" /xml:$_.Name-testresult.xml $file
if($LastExitCode -ne 0)
WRITE-HOST "Test have failed for $file"-ForegroundColor RED
WRITE-HOST "Test have passed for $file"-ForegroundColor GREEN
#$null = Remove-Event $_.EventIdentifier

Register-ObjectEvent -InputObject $fsw -EventName Changed "FileChanged" -Action $action
Register-ObjectEvent -InputObject $fsw -EventName Created "FileCreated" -Action $action

Note that you will either have to explicit unregister your event handlers or kill powershell to get rid of the handlers. Cancel the watcher by hitting ctrl+c and then Unregister by runnning these lines

unregister-event "FileCreated"
unregister-event "FileChanged"

*The stuff we are doing is to do with inheritance and inner test fixtures to give us a BDD experience without the drama of the BDD frameworks, that personally I still dont like. We are still a fair way off the TDD experience of the Ruby kids.
