I am pretty happy with how thorough the behat tests mod/quiz/tests/behat/editing_require_previous.feature and mod/quiz/tests/behat/attempt_require_previous.feature are for this. However, for a new feature like this, it would be good to have some human eyeballs on it too. Rather than give detailed steps (if you want those, read the Behat tests) and let you do some exploratory testing: If the quiz allows it (How questions behave: Interactive, or Immediate) Then, on the Edit quiz page, there are some lock icons that let you say the student can only see question N once question N - 1 has been answered. But, only if Questoin N - 1 makes that sensible (e.g. you can't depend on an Essay or Description). When doing this, we don't try to analyse random questions. You can always depend on a random question, but it that becomes an Essay in a particular attempt, the dependency has no effect. The whole point of this is that when a student attempts the quiz (or a teacher previews) you cannot see Question N until you have finished Question N - 1 (Checked it until there are no more tries.) Once the whole quiz is submitted, then on the review page, all questions are visible, even if you could not see them during the attempt. The point of this feature is so you can have quizzes like: Q1: In Moodle, where do you go to add users to your course? A1: Course administration -> Users -> Enrolled users Q2: On the Enrolled users screen, how do you add another user?
