As there are CSS changes, please make sure you clear the site / browser cache before testing. Open up a forum activity and start a new discussion Drag a file into the 'attachments' area check that the filename + progress bar is displayed as expected check the progress bars are hidden and the normal icon/thumbnail is shown once the upload is complete Drag 2 more files (at the same time) into the area check the filenames + progress bars are both shown check the progress bars are hidden and the normal icon/thumbnail is shown once the upload is complete Delete all the files - check the drag & drop message is displayed correctly Upload a file with a very long filename ( > 50 chars) - check the name is truncated properly Attempt to upload a file greater than the current filesize limit - check the uploaded files are redisplayed after the error message is dismissed Upload the same file twice, then cancel the 'overwrite / rename' dialog - check the uploaded files are redisplayed correctly Visit Site admin > users > upload users Drag and drop a file into the filepicker box Check the progress bars are displayed correctly Check the file is displayed correctly after the upload is complete Delete the file, then drag and drop a file that is greater than the filesize limit check the file display returns to normal after the error message is dismissed Visit a course page and turn editing on Drag and drop a file onto the course Make sure the styling of the progress bar has not been broken by the CSS changes Note - this will need testing in at least Firefox and Chrome. Preferably also IE10 (IE9 and below do not support drag and drop upload). On supported browsers, the progress bar should have rounded corners and a subtle drop shadow to the right of the internal green bar.
