Variables inside the assertion script block

[DexterPOSH]

Since the Assertion in the PoshSpec is placed inside a scriptblock, how does one reference variables in it e.g below works fine when the assertion is hardcoded -:

Describe test {
    Service Bits Status {Should be 'Running'}
}

But when a variable is placed in the assertion, it can't see them e.g.

Describe test {
    $DesiredStatus = 'Running'
    Service Bits Status {Should be $DesiredStatus}
}

Above gives me the error -:

Describing test
 [-] Service property 'Status' for 'Bits' Should be $DesiredStatus 123ms
   Expected: {}
   But was:  {Running}
   1: Get-Service -Name 'Bits' | Select-Object -ExpandProperty 'Status' | Should be $Desir
edStatus
   at <ScriptBlock>, <No file>: line 1
   at <ScriptBlock>, C:\Users\Deepak_Dhami\Documents\GitHub\poshspec\Private\Invoke-Poshsp
ecExpression.ps1: line 12

The idea is to use a CSV file as a template for all the service and their compliant status.
How do I do something like this with PoshSpec ?

Describe 'IT Compliance for Services' {
    $ObjectFromCSV = @([PSCustomObject]@{
        Name='Bits';
        Status='Stopped'
    })

    $ObjectFromCSV.Foreach({
        Service $PSItem.Name Status {Should be $PSItem.Status}

    })
}

I would say that is an architectural limitation of PoshSpec that will not be addressed in the short-term. I think there are two work arounds: you can create a loop for each State you want to test and hard code the test value; or, you can declare a variable with Global scope.
