+One JSON object describing the course scenario: `{"groupmode":"separategroups|visiblegroups|nogroups","accessallgroups":true|false,"viewer":"<username>"}`. `groupmode` selects the course group mode, `accessallgroups` says whether the viewer holds moodle/site:accessallgroups in the course context, and `viewer` picks the logged in fixture user (teacher, user0, user1, user21, user22, userall, usertch).
