Testing this is most easy if you are able to edit the Moodle code. you should have developer debug on for this. Set up Create a quiz. Add three multiple-choice questions, each on a separate page. Make sure there is a student enroled in the course. Hack code Edit question\type\multichoice\question.php, and at the top of the function apply_attempt_state, insert these two lines. debugging( "In apply_attempt_state" ); This means that you will get debug info on screen every time a question is initialised. Test Log in as student. Go to the quiz. Verify that there are no 'In apply_attempt_state' messages. Click 'Start attempt'. Verify that you do not get stopped on the page with URL startattempt.php. Verify that on the first page of the quiz (attempt.php) there is a single 'In apply_attempt_state' message. Answer the question, and click 'Next'. Verify that it stops on processattempt.php with a single 'In apply_attempt_state' message, and the message 'Error output, so disabling automatic redirect.' Click 'Continue'. Verify that you are on page 2 of the quiz with a single 'In apply_attempt_state' message. Click 'Finsh attempt...'. Verify that you are on processattempt.php with one 'In apply_attempt_state' message. Click contine. Verify that you are on the quiz summary page (summary.php) with no 'In apply_attempt_state' messages. Do 'Submit all and finish'. Verify that it stops on processattempt.php with three 'In apply_attempt_state' messages Click 'Continue'. Verify that you are on the attempt review page (review.php) with three 'In apply_attempt_state' messages (cause the review shows all questions on one page. Click 'Finish review'. Verify that you are on the quiz info page (view.php) with no 'In apply_attempt_state' messages. Don't forget to undo the edit in question\type\multichoice\question.php once you have finished. In addition to this manual test, the unit test and Behat tests will provide a pretty thorough regression test.
