I found this little snippet online that allows you to preparse your Powershell scripts to ensure there are no syntax errors in it. This is useful if you need to know the script is error-free but are otherwise unable to run it.

# Contents of file TestScript.ps1
param($path, [switch]$verbose)

if ($verbose) {
    $VerbosePreference = ‘Continue’
}

trap { Write-Warning $_; $false; continue }
& `
{
    $contents = get-content $path
    $contents = [string]::Join([Environment]::NewLine, $contents)
    [void]$ExecutionContext.InvokeCommand.NewScriptBlock($contents)
    Write-Verbose "Parsed without errors"
    $true
}
