With Master only You will need to do at least 3 upgrades to test this fully Starting in 3.7.x Upgrade straight to master with this patch Confirm there are no errors Confirm that displaygroupingfavourites is listed as a new setting Starting in 3.8.x or master without this patch (before-patch) Go to Admin settings > Plugins > Course overview, make sure displaygroupingstarred is enabled Move to master with this patch (after-patch) Run the upgrade Confirm there are no errors Confirm that displaygroupingfavourites is not listed as a new setting Go to Admin settings > Plugins > Course overview, make sure displaygroupingfavourites is enabled Run the SQL SELECT * FROM mdl_config_plugins WHERE name = 'displaygroupingstarred'; and confirm that no rows are returned Starting in 3.8.x or master without this patch (before-patch) Go to Admin settings > Plugins > Course overview, and disable displaygroupingstarred In config.php, add this line $CFG->forced_plugin_settings = ['block_myoverview' => ['displaygroupingstarred' => 1] ]; Go to Admin settings > Plugins > Course overview, and confirm displaygroupingstarred is now enabled with a config.php message Move to master with this patch (after-patch) Run the upgrade Confirm you see this message during the upgrade: Setting block_myoverview->displaygroupingstarred has been renamed to block_myoverview->displaygroupingfavourites. Old setting present in config.php. If you use CLI upgrade, the >s will be escaped. This limitation is present in other core upgrade code, so I assume this is normal. Confirm that displaygroupingfavourites is not listed as a new setting Go to Admin settings > Plugins > Course overview, make sure displaygroupingfavourites is disabled In config.php, change displaygroupingstarred to displaygroupingfavourites Go to Admin settings > Plugins > Course overview, and confirm displaygroupingfavourites is now enabled with a config.php message Run the SQL SELECT * FROM mdl_config_plugins WHERE name = 'displaygroupingstarred'; and confirm that no rows are returned With 3.8 and Master Run behat Run with the --tags=@block_myoverview Test function In Admin settings > Plugins > Course overview, make sure displaygroupingstarred (for 3.8) and displaygroupingfavourites (for master) is enabled Create a user in at least one course This can be admin, you just need to enrol them in the courses as a student/teacher You may need many courses if you want to test all the permutations of the course overview filter On the dashboard, make sure you have the Course Overview block present Star a course Set the course filter to Starred Make sure the output is as expected Reload the page and confirm that the previous setting is remembered, and displays the correct courses Repeat the last 3 steps but with the other filter options Set the filter back to Starred As admin, navigate back to Admin settings > Plugins > Course overview, and disable displaygroupingstarred (for 3.8) or displaygroupingfavourites (for master) Go back to the dashboard as your user Confirm that Starred is not selected, and some other item is, most likely All (except). Confirm that the courses listed seem to match the expected output for the select filter Confirm that there are no errors (js console, PHP, etc)
