Setup Create a SCORM activity. Download the RuntimeMinimumCalls_SCORM12.zip and attach it to your SCORM activity. Login as a student and attempt the SCORM activity. Do this for at least one more student. Feel free to do multiple attempts as well. Login as the teacher again and go to the SCORM activity. Open the " Reports " tab. Test Check the "Basic report" tab Confirm that you see a checkbox on the column header of the attempts table's first column. Let's call this the master checkbox. Confirm that without any item being selected on initial load, the " Delete selected attempts " button is rendered as disabled. Check the behaviour of the master checkbox. Confirm that: When it's ticked, all attempts become selected and its hidden label becomes " Deselect all " (you might wanna inspect using the dev tools of your browser) When everything's selected and you untick it, all attempts become deselected and its label becomes " Select all " Check the effect of clicking of one or more checkboxes beside each attempt. Confirm that: When you tick all checkboxes, the master checkbox becomes ticked and its hidden label becomes " Deselect all " When all checkboxes are ticked and you untick at least one checkbox, the master checkbox becomes unticked and its hidden label becomes " Select all " Check the behaviour of the " Delete selected attempts " button. Confirm that: When at least one checkbox is selected, the button is enabled. When there's no checkbox selected, the button is disabled. Repeat the test for the " Interactions report " and the " Objectives report " pages.
