Enable completion in Moodle and in your course. Add some resources and activities with manual and automatic completion. Access that course using the app and check that you can see the right completion icon in each module (or no completion icon if not enabled). Check that you can change the completion of manual completion resources. The list is updated when doing so. In Moodle, add a module with logging supported (forum, resource, url, ...) and set automatic completion when viewed. In the app check that the module is marked as not completed, view that module in the app, go back to the resources list and check that now is marked as completed. In Moodle, add a module whose visibility depends on another module completion (not completed yet). Check that you can't see that resource in the app. Complete the required module (either by manual completion or viewing it in the app) and check that now the new module is in the list.
