"""
This test ensure `inherit_id` update is correctly replicated on cow views.
The view receiving the `inherit_id` update is either:
1. in a module loaded before `website`. In that case, `website` code is not
   loaded yet, so we store the updates to replay the changes on the cow views
   once `website` module is loaded (see `_check()`). This test is testing that
   part.
2. in a module loaded after `website`. In that case, the `inherit_id` update is
   directly replicated on the cow views. That behavior is tested with
   `test_module_new_inherit_view_on_parent_already_forked` and
   `test_specific_view_module_update_inherit_change` in `website` module.
