Hello,

Wondering what would be the "best practice" to separate code for running in debug/production environment. For example I want to default value for email to be different when I deploy to production vs when I develop powershell scripts.
Will it be environment value, relying on machine name, switch parameter?

Hi there!

This really depends on your organization's practices and policies, you might have trouble finding a 'best practice'. You might consider a very simple configuration file, perhaps based on JSON (if humans need to modify if).

I'm sure it has its weaknesses, but I find the configuration complexity clock worth considering.

Cheers!

If you are actually using Write-Debug for debugging, you could do something simple like this:

[CmdLetBinding()]
param()

Write-Debug "Starting script"

$mailParams = @{
    To="productionemail@mycomp.com" 
    From="admin@mycomp.com"
    Subject="Hello"
    Body="Hello"
    BodyAsHtml=$true
    SmtpServer="smtprelay.mycomp.com"
}


if ($PSBoundParameters.ContainsKey('Debug')) {
    Write-Debug "Updating recipient..."
    $mailParams.Set_Item("To", "Testing@mycomp.com")
}

$mailParams
Send-MailMessage @mailParams

If you just call the script, it sends to your default params...

However, if you pass the -Debug switch to the script we detect that it's been passed and update the TO...

You could do the same thing with Verbose so don't have to answer prompts all day long.
