Several additions to External Tool (LTI)

A lot of the LTI service related changes can be tested with the following: Create a new General Tool For the Launch URL, use: http://www.imsglobal.org/developers/LTI/test/v1p1/tool.php Upon launch you can verify launch parameters. In addition, upon launch, there is a link to send back grade data. In order to test this, your site must be publicly available. But, with this, you can test reading the current grade in Moodle, sending back a new grade to Moodle or deleting the grade in Moodle. For the ltisource plugin updates, one would have to author a plugin to test this functionality. If that is not possible, then just testing to make sure that the new code doesn't cause regression should suffice: Ensure you can backup/restore a General Tool. Ensure you can perform an LTI launch. Use the instructions above to test launching. For grade updates, ensure grades in the gradebook are updated correctly when the grade is changed in the General Tool instance settings. To fully test grades though, you need to test on a public site and send grade data to the site. To do this, please refer back up to the first set of testing instructions. For testing the resize JS in mod/lti/view.php, use the following: Create a new General Tool For the Launch URL, use: http://www.imsglobal.org/developers/LTI/test/v1p1/tool.php Select "Embed without blocks" for the Launch Container. Save changes and view the activity. Resize the window. The embedded LTI object should resize after the window has resized. For testing deprecated mod/lti/grade.php file: Create a General LTI activity. (Launch URL can be http://www.imsglobal.org/developers/LTI/test/v1p1/tool.php ) Make sure the General LTI activity is graded. Navigate to the course gradebook and look at the Grader Report. Find the column for the General LTI activity and click on the column header (EG: click on the name of the activity). The link should take you to viewing the General LTI activity. If debugging is set to developer, then it will also show you a debug message about the mod/lti/grade.php file being deprecated. For testing changes to mod/lti/settings.php file: Ensure that Site administration > Plugins > Activity modules > LTI page still loads up correctly as it did before this ticket. Any problems should apparent like, section error or LTI section is not a page, but rather a folder. It should only be a folder if there is a LTI source plugin that has a settings.php file. Lastly, be sure to run unit tests for mod/lti.
