Try-and-trap-catch-terminating-errors

try and trap catch only terminating and semi-terminating errors. Thus, if the current error action preference is not Stop then non-terminating errors are not caught. Note that the default PowerShell error action preference is Continue.

In order to catch all errors use

    $ErrorActionPreference = 'Stop'

Scripts

• test.1.1.try.ps1 - try does not catch an error.
• test.1.2.try.ps1 - try catches an error.
• test.2.1.trap.ps1 - trap does not catch an error.
• test.2.2.trap.ps1 - trap catches an error, then continue.
• test.2.3.trap.ps1 - trap catches an error, then break.
