This issue should be tested in Android and iOS. Only one device of each is enough, and it doesn't matter if it's tablet or phone (the UI is the same for both). Basically, test that the ordering question type works similar as in Moodle LMS. Some things to take into account: In the app, to drag and drop an item you need to click the "handler" (the "button") at the start of the item, instead of having to click the whole item. This is to avoid problems with scrolling. The app does NOT support "Layout of items" = "Horizontal". In the app, the items are always displayed vertically. Check different "Grading type", e.g. "Absolute position", "Relative to correct position", etc. There's no need to test them all, IMO testing 2-3 or so is enough. These grading types don't change anything when answering, but the info and colors displayed when reviewing does change. Test both with deferred feedback and with immediate feedback. Please notice that with immediate feedback, the colors of correct/incorrect aren't displayed when you use the "Check" button, they're only displayed when you finish the attempt. Test that it works offline. Extra test: install the qtype_ordering plugin in a 4.3 site or older, and test that the app says the question isn't supported. We only support the core question of Moodle 4.4.
