Verifies the keys and values in a session configuration file.


Test-PSSessionConfigurationFile [-Path] <String> [<CommonParameters>]


The Test-PSSessionConfigurationFile cmdlet verifies that a session configuration file contains valid keys and the values are of the correct type. For enumerated values, the cmdlet verifies that the specified values are valid.

By default, Test-PSSessionConfigurationFile returns $True if the file passes all tests and $False if it does not. To find any errors, use the Verbose common parameter.

Test-PSSessionConfigurationFile verifies the session configuration files, such as those created by the New-PSSessionConfigurationFile cmdlet. For information about session configurations, see about_Session_Configurations ( For information about session configuration files, see about_Session_Configuration_Files (

This cmdlet was introduced in Windows PowerShell 3.0.


Example 1: Test a session configuration file

PS C:\> Test-PSSessionConfigurationFile -Path "FullLanguage.pssc"

This command uses the Test-PSSessionConfigurationFile cmdlet to test a new session configuration file before using it in a session configuration.

Example 2: Test the session configuration file of a session configuration

PS C:\> Test-PSSessionConfigurationFile -Path (Get-PSSessionConfiguration -Name Restricted).ConfigFilePath

This command tests the session configuration file that is being used to in the Restricted session configuration. The value of the Path parameter is a Get-PSSessionConfiguration command that gets the Restricted session configuration. The path of the session configuration file is stored in the value of the ConfigFilePath property of the session configuration.

Example 3: Test all session configuration files

PS C:\> function Test-AllConfigFiles
    Get-PSSessionConfiguration | ForEach-Object { if ($_.ConfigFilePath)
    {$_.ConfigFilePath; Test-PSSessionConfigurationFile -Verbose `
     -Path $_.ConfigFilePath }}

This function tests all session configuration files that are used in all session configurations on the local computer.

The function uses the Get-PSSessionConfiguration cmdlet to get all session configurations on the local computer. The command pipes the session configuration to the ForEach-Object cmdlet, which runs a command on each of the session configurations.

The ConfigFilePath property of a session configuration contains the path of the session configuration file that is used in the session configuration, if any.

If the value of the ConfigFilePath property is populated (is true), the command gets (prints) the ConfigFilePath property value. Then it uses the Test-PSSessionConfigurationFile cmdlet to test the file in the ConfigFilePath value. The Verbose parameter returns the file error when the file fails the test.



Specifies the path and file name of a session configuration file (.pssc). If you omit the path, the default is the current folder. Wildcard characters are supported, but they must resolve to a single file. You can also pipe a session configuration file path to Test-PSSessionConfigurationFile.
