<#
    .SYNOPSIS
        Configures the tests to run with the authentication information stored in AppVeyor
        (if that information exists in the environment).
 
    .DESCRIPTION
        Configures the tests to run with the authentication information stored in AppVeyor
        (if that information exists in the environment).
 
        The Git repo for this module can be found here: http://aka.ms/PowerShellForGitHub
 
    .NOTES
        Internal-only helper method.
 
        The only reason this exists is so that we can leverage CodeAnalysis.SuppressMessageAttribute,
        which can only be applied to functions.
 
        We call this immediately after the declaration so that AppVeyor initialization can heppen
        (if applicable).
