I have created a CSV file with WooCommerce tax rates and want to import it with a PHP script. How can I do this?

I wrote this code:

<?php

// path to the file on my system
require "../wp-content/plugins/woocommerce/woocommerce.php";
$wc_importer = new WooCommerce\Admin\Importers\WC_Tax_Rate_Importer();
$wc_importer->import('test.csv');

but when I run it like this:

$ php -d display_errors=1 -f import.php

nothing happens. There is no output to the console. Thank for your help.

PS: I understand this site does not welcome WooCommerce questions but I believe this question is more about PHP programming than WooCommerce hence trying to post it here.

I think there could be couple of issues here:

1. How to import the package correctly
2. How to direct messages to console
