Drupal 8.x

I maintain several drupal 8 websites using the same instance. They all uses a custom module I developed.
I have a .po file containing the translations I need. I can import them using the admin interface and all is well.

How can I setup automatic import of the module .po file ? And trigger the update/import on all websites when the .po file is updated ? I've spent much time in the drupal 8 documentation to no luck, unfortunately.

Hello everybody,
I am trying to do the porting of field_permission module for Drupal8 but I am having some problems in developing tests.

The form sending test works and passes all tests only by removing the default values from the checkbox field of the form, while when manually tested, it works correctly.

I understand that in a testing phase, checkboxes can only be activated and cannot be deactivated,
and now when I launch the test, all checkbox fields are selected if the field contains a default value.
