You may have noticed that there during testing of Moodle 2.5 release there are little warnings popping out of the woodwork whilst testing like:
Did you remember to call setType() for 'id'? Defaulting to PARAM_RAW cleaning.
This is a new developer warning, to help us improve the security/robustness of our forms in Moodle, introduced by MDL-34311.
We've noticed that a few of your have been encountering these messages and passing your tests because it does not affect the functionality of Moodle. I'd like to ask if you do encounter these warnings (or any other warning whilst running QA tests), please fail the test.
We are aiming to eliminate any of these developer warnings before release, and having the failed QA tests is a good way to ensure we do not miss any of them.
Thanks a lot for all your hard work testing Moodle 2.5!
