When creating a technique, if you use a condition based on a variable content, it will not canonify its value, leading to malformed conditions.
The logic should already be written since on the CfEngine technique side it is properly canonified.

We currently generate something like:

function Test-Technique {
  [CmdletBinding()]
  param (
      [parameter(Mandatory=$true)]
      [string]$reportId,
      [parameter(Mandatory=$true)]
      [string]$techniqueName,
      [parameter(Mandatory=$true)]
      [string]$File,
      [switch]$auditOnly
  )

  $local_classes = New-ClassContext
  $resources_dir = $PSScriptRoot + "\resources" 

  $local_classes = Merge-ClassContext $local_classes $(File-Content -File "${file}" -Lines "my_content" -Enforce "true" -componentName "File content" -reportId $reportId -techniqueName $techniqueName -auditOnly:$auditOnly).get_item("classes")

  $class = "any.(file_lines_present_${file}_repaired)" 
  if (Evaluate-Class $class $local_classes $system_classes) {
    $local_classes = Merge-ClassContext $local_classes $(File-Content -File "C:\result.txt" -Lines "un peu de contenu
sur
plusieurs lignes" -Enforce "true" -componentName "File content" -reportId $reportId -techniqueName $techniqueName -auditOnly:$auditOnly).get_item("classes")
  } else {
    _rudder_common_report_na -componentName "File content" -componentKey "C:\result.txt" -message "Not applicable" -reportId $reportId -techniqueName $techniqueName -auditOnly:$auditOnly
  }

}

And we want something like:

function Test-Technique {
  [CmdletBinding()]
  param (
      [parameter(Mandatory=$true)]
      [string]$reportId,
      [parameter(Mandatory=$true)]
      [string]$techniqueName,
      [parameter(Mandatory=$true)]
      [string]$File,
      [switch]$auditOnly
  )

  $local_classes = New-ClassContext
  $resources_dir = $PSScriptRoot + "\resources" 

  $local_classes = Merge-ClassContext $local_classes $(File-Content -File "${file}" -Lines "my_content" -Enforce "true" -componentName "File content" -reportId $reportId -techniqueName $techniqueName -auditOnly:$auditOnly).get_item("classes")

  $class = "any.(file_lines_present_" + $(Canonify-Class $file) + "_repaired)" 
  if (Evaluate-Class $class $local_classes $system_classes) {
    $local_classes = Merge-ClassContext $local_classes $(File-Content -File "C:\result.txt" -Lines "un peu de contenu
sur
plusieurs lignes" -Enforce "true" -componentName "File content" -reportId $reportId -techniqueName $techniqueName -auditOnly:$auditOnly).get_item("classes")
  } else {
    _rudder_common_report_na -componentName "File content" -componentKey "C:\result.txt" -message "Not applicable" -reportId $reportId -techniqueName $techniqueName -auditOnly:$auditOnly
  }

}

The diff is on the lines:

$class = "any.(file_lines_present_${file}_repaired)" 

and

$class = "any.(file_lines_present_" + $(Canonify-Class $file) + "_repaired)"
