Get-Name with extra for ScriptBlock

Get-Name.ps1

function Get-Name {
    [CmdletBinding()]
    param(
        [String]$Name = 'you'
    )

    'Hello, {0}. Script root is {1}' -f $Name, $PSScriptRoot
}

Get-Name -Name Shane

wouldn't this be testable?

param([switch]$Testing)

function Get-Name-Sourcing{
   . (join-path $PSScriptRoot 'lib\MyLogging.ps1')
}
function Get-Name {
   [CmdletBinding()]
   param(
      [String]$Name = 'you'
   )

   LogIt "Said: Hello, $Name" #From MyLogging.ps1
   'Hello, {0}' -f $Name
}

if(!$Testing){
   Get-Name-Sourcing #split out so it can be mocked
   Get-Name -Name Shane
   Remove-Item Function:\Get-Name-Sourcing
}

Yup, looks good to me. Nice one!

I'll say that it may be difficult to get everyone in the company/community to use this style. Especially if they're starting with PowerShell and wondering "Why do I have to do this when I just want to run a script?!"

Overall, though, yup! An absolutely superb way to ensure these scripts are testable
