Generic Notes These testing instructions should be carried out twice (once with jsrev = -1, once without) to confirm that the correct versions of JS are used and work as expected. Tip : Open your browser's developer toolkit, open the 'Network' activity tab, and restrict to 'Scripts'. Note : You may find that the script you're looking for is included with a number of other scripts - this is because of our combo loading. You can turn off comboloading to make it easier to check the relevant script by setting $CFG->yuicomboloading = false; , but you should check that functionality works with combo loading enabled. To test the minified code: Required settings: // Ensure you aren't overriding $CFG->jsrev $CFG->debug = 0; Notes Check that the minified version of this module is loaded. It will have -min.js in the filename but please ensure content is also be minified and to test the non-minified code: Required settings: $CFG->jsrev = -1; $CFG->debug = (E_ALL | E_STRICT); Notes Check that the non-minified version of this module is loaded. It will have -debug.js in the filename and the file content should not be minified. Module-specific test instructions Open any page in Moodle which uses the navigation block Confirm that you can still expand/collapse nodes Confirm that when you expand a Course node, there is a call to /lib/ajax/getnavbranch.php and the branch loads any relevant content Testing keyboard use Use the tab key to get to the navigation Confirm that left/right open and close branches Confirm that enter/space toggle opening/closing of branches Open down to a course and tab to the Participants list Confirm that space always toggles a node Confirm that the 'enter' key toggles the 'Current course' node Confirm that the 'enter' key selects the 'Participants' node
