Testing needs to be done for the following question types: Drag and drop onto image (qtype_ddimageortext) Drag and drop markers (qtype_ddmarker) Matching (qtype_match) For testing you need a Moodle course and at least two users who can create questions. Create a Moodle course Create two user (eg. editingteacher), teacher 1 and teacher2. Enrol teacher1 and teacher2 in the your course Login as teacher1 into this course Go to the question bank Press "Create a new question ..." button Choose a 'Drag and drop onto image' and press the "Add" button While filling the question fields, make a note of the original default value of ‘Default mark’, ‘Shuffle drag items each time question is attempted’ fields, then change the values of these fields and remember them Press "Save changes" button Press "Create a new question ..." button again Choose a 'Drag and drop onto image' the press "Add" button Verify " that the values of the fields you have changed in previous 'Drag and drop onto image' question appear on the form as defaults. Logout Login as teacher 2 into this course Go to the question bank Press "Create a new question ..." button Choose a 'Drag and drop onto image' and press the "Add" button Verify  that default values are displayed again (so values changed for teacher1 previously doesn't appear). In other words, when user create a new question and modify some default setting, they are saved as user preference, so that the next time when a new question of the same type is created by the same user, the default values are taken from the user_preferences table for this user. I.e, teacher1 gets their preference as defaults for a new 'Drag and drop onto image', whereas teacher2 will get original default values .   The testing has to be done in the same way for: "Drag and drop markers" (qtype_ddmarker) with fields: 'Default mark' 'Highlight drop zones which have not had the correct marker dropped on them' 'Shuffle drag items each time question is attempted' "Matching" (qtype_match) with fields: 'Default mark' 'Shuffle'
