Powershell Script throwing error when I call a function

Question

I am getting the below error when i call the method in PowerShell. Any help would be thankful very much.

Error:

Error in The term 'Test' is not recognized as the name of a cmdlet, function, script file , or operable program. Check the spelling of the name, or if a path was included , verify that the path is correct and try again.

Code

Try
{   
    Test
}
Catch
{
    $ErrorMessage = $_.Exception.Message
    Write-Host "Error in" 
    Write-Host $ErrorMessage
}


function Test()
{
  Write-Host "Test Method Called"
}

Answer 1

The reason your call to Test fails is that PowerShell scripts are not pre-compiled, but evaluated from top to bottom.

Since the Test function is only declared at the end of your script, it does not "exist" when the Try-Catch block is executed.

Simply swap the order:

function Test()
{
  Write-Host "Test Method Called"
}

Try
{   
    Test
}
Catch
{
    $ErrorMessage = $_.Exception.Message
    Write-Host "Error in" 
    Write-Host $ErrorMessage
}
