Notes Please test on both the Clean and Boost themes. You don’t need to run the full set of tests on each theme, you just need to confirm that the drag / drop styling works on both themes. Setup Log in as admin Create a course Enrol a user as a teacher (t1) Enrol a user as a student (s1) Assignment due date as teacher Log in as t1 Create an assignment activity Allow online text as a submission type Enable the cutoff date and set it to a couple of dates after the due date (but before the "Remind me to grade by" date) Make sure all availability dates are set to 8am on their respective days Click save and display Click edit settings to return to the assignment settings page Cog icon up the top right > edit settings In a separate tab or window go to the calendar View the appropriate month for the due date Confirm that you see an assignment event for the due date Note: The styling isn’t correct but that’s a separate issue (see MDL-60176 ) Start to drag the assignment event Confirm that the days after the cutoff day are greyed out (the day of the cutoff is still acceptable because setting the due date to the cutoff date is valid, according to the mfrom validation) Confirm that the days prior to the allow submissions from day are greyed out (same applies as above) Confirm that you get an error message when you try to drop the event on an invalid day Confirm that if you drop the event on a valid day that the calendar is updated correctly Confirm that the due date for the assignment is updated (you can reload the tab with the settings open to see the updated due date value) Note: Only the date for the due date should be updated, the time will not be changed. In the assignment settings tab change the “Allow submissions from” time from 8am to 8:05am Change the “cut-off date” time from 8am to 7:55am Reload the calendar tab Confirm that the day of the “Allow submissions from” date is no longer a valid drop zone (because the due date has a time of 8am so dropping it there would be earlier than the 8:05 cutoff) Confirm that the day of the “Cut-off date” is not longer valid (same reasoning as above) In the assignment settings tab change the cut off date to after the "remind me to grade by" date Reload the calendar Confirm that dragging the due date is now bound by the "remind me to grade by" date rather than the "cut-off date" (since it's now the earlier of the two).
