This is very similar to MDL-77090, but at the time, I missed that this
also needed to be handled. (Question metadata is, I think, only used
by the quiz 'Try another question like this one' feature.)
The behaviour-specific data was getting corrupted when the regrade
recreated the first step, because $oldstep->get_behaviour_data() was
stripping off the leading '-' characters from the names, and they were
not being added back.
To all the walkthrough, questiontype, question, upgradelibnewqe,
behaviourtype_test and edit_form testcase classes::
- Namespaced with component[\level2-API]
- Moved to level2-API subdirectory when required.
- Fixed incorrect use statements with leading backslash.
- Remove file phpdoc block
- Remove MOODLE_INTERNAL if not needed.
- Changed code to point to global scope when needed.
- Fix some relative paths and comments here and there.
- All them passing individually.
- Complete runs passing too.
Special mention to:
- When belonging to other component and being valid api:
- form related tests have been moved to tests/form subdir.
