Access External Variable from with-in Mock Script Block (Pester)

Pretend I have a function like...

function Get-Something {
  return Get-DogShit
}

...in my Pester test script...

$var = 1

Mock 'Get-Dogshit' { return $var }

it 'should return true' {
  Get-Something | should $var
}

This doesn't work, but you see what I'm trying to do here? I want to get the value from a local variable into a MOCK script block. I want to avoid hard coding the return value in the mock and the expected result in the it-block. Any ideas on how I can achieve this?

Solution

  • Wasn't sure if it would work as not messed with pester before but apparently it follows the same scope rules as standard PowerShell.

    So $script:var = 1, and the brute-force $global:var = 1 if it doesn't or if you need to call it from outside the script scope.
