CI tests will check this. And manual testing instructions @ MDL-66743 (that are a dupe of the ones originally here) will complete the testing indirectly. ---- ---- Were: The new scenario added in mod/quiz/tests/behat/backup.feature should be sufficent to verify that this change has not caused any regressions for activity modules. If you want to do a manual test, find a quiz with some attempts, and make a backup and restore including user data. (If you really want to make the effort, you could also instal mod_studentquiz, and run all its auomated tests, or test its backup/restore manually. However this is probably overkill.) To test that the change allows other types of plugins to backup and restore question attempt data, run all the automated tests from the backup-restore branch of https://github.com/moodleou/moodle-report_embedquestion (which also requires filter_embedquestion installed). You will also need to have applied the fix from MDL-66743 . This can be done with the following commands in the root of your Moodle workspace: git clone https://github.com/moodleou/moodle-filter_embedquestion.git filter/embedquestion/ git clone -b backup-restore https://github.com/moodleou/moodle-report_embedquestion.git report/embedquestion/ php admin/tool/phpunit/cli/init.php vendor/bin/phpunit --testsuite report_embedquestion_testsuite
