Test-WithCulture

SYNOPSIS

Test your PowerShell code using a different culture.

SYNTAX

scriptblock (Default)

Test-WithCulture [-Culture] <CultureInfo> [-Scriptblock] <ScriptBlock> [-ArgumentList <Object[]>]
[<CommonParameters>]

file

Test-WithCulture [-Culture] <CultureInfo> -FilePath <ScriptBlock> [-ArgumentList <Object[]>]
 [<CommonParameters>]

When writing PowerShell commands, sometimes the culture you are running under becomes critical. For example, European countries use a different datetime format than North Americans which might present a problem with your script or command. Unless you have a separate computer running under the foreign culture, it is difficult to test. This command will allow you to test a scriptblock or even a file under a different culture, such as DE-DE for German.

Note that this command is not an absolute test. There may be commands that fail to produce the alternate culture results you expect.

EXAMPLES

Example 1

PS C:\> Test-WithCulture de-de -Scriptblock {(Get-Date).addDays(90)}
06.10.2026 15:01:50

PS C\> Test-WithCulture fr-fr -Scriptblock {
  Get-winEvent -log system -max 500 |
  Select-Object -Property TimeCreated,ID,OpCodeDisplayName,Message |
  Sort-Object -property TimeCreated |
  Group-Object {$_.TimeCreated.ToShortDateString()} -NoElement
}
