Setup Set the autosave frequency (autosavefrequency) to something low i.e. 5 seconds. Saving text Load a page that has an atto editor on it (i.e. profile settings page) and begin entering text. Wait 5 seconds for the entered text to auto-save Observe the notification that appears. Make sure it looks appropriately sized and doesn't interfere with anything else. Repeat the same test but for a page with many editors, i.e. the edit quiz question page for a multiple choice question. Loading drafts After performing the previous set of tests, reload your page and ensure that drafts are loaded correctly and that the notification behaves appropriately. Pages with autosave disabled As a student completing a quiz question with an atto editor (i.e. essay question), ensure that the editor_atto_wrapper class is not inserted into any div in the DOM. This is intentional as these quiz has it's own autosave and we shouldn't be inserting padding in these editors. Error cases Enter some text into an editor and make sure a draft saves fine. Verify this by finding it in the mdl_editor_atto_autosave table (SELECT * FROM mdl_editor_atto_autosave). Cause an error condition to occur. We can do this by changing the mdl_editor_atto_autosave table to a different name (ALTER TABLE mdl_editor_atto_autosave RENAME TO mdl_asdasdasf). Reload the page. You should observe an error notification on the editor. Don't forget to change the table name back. LTR/RTL Ensure that everything behaves as expected in both right-to-left and left-to-right languages.
