Prerequisite Note: This test is using 2 apps to test 1.3 and 1.1 interactions; any other LTI 1.3 Test application could be used instead. Steps should be rather identical, what matters is to be able to post 2 resources with the same resource id and a tag value, both under 1.1 and 1.3 flows.

We verify the restored backup still contains the resourceid (since it is now stored on a new location). As admin, restore the attached course backup-moodle2-course-2-ztestcourse38-20200526-1227-nu.mbz Restore as new course Keep all default options Perform restore Once in the restored course Verify 2 ZTest links are present Click on any of those Verify ZTest opens without error Click AnyCall Click get lineitems button and click send button Verify payload matches the following JSON, just the id field should differ: [ { "id" : "https://moodle.zeedeeyou.com/mod/lti/services.php/4/lineitems/29/lineitem?type_id=1" , "label" : "ZTest Quiz No Resource Id" , "scoreMaximum" : 20 , "resourceId" : "" , "tag" : "" , "resourceLinkId" : "23" , "ltiLinkId" : "23" }, { "id" : "https://moodle.zeedeeyou.com/mod/lti/services.php/4/lineitems/30/lineitem?type_id=1" , "label" : "ZTest Quiz With ResourceId" , "scoreMaximum" : 20 , "resourceId" : "ztest-quiz-1" , "tag" : "" , "resourceLinkId" : "24" , "ltiLinkId" : "24" }, { "id" : "https://moodle.zeedeeyou.com/mod/lti/services.php/4/lineitems/31/lineitem?type_id=1" , "label" : "API ZTest 748" , "scoreMaximum" : 22 , "resourceId" : "748" , "tag" : "finalgrade" } ]
