Requirments It is quite difficult to write testing instructions for all possible edge cases effected by this patch. Given test instructions might not be 100% accurate, also will require a basic understanding of the changes made by the patch and expected results. A course with two groups (1,2) with atleast 2 student in each (student 1,2 - group 1 and student 3-4 in group 2) Create a discussion by each student in a forum, and make a reply by the same user to it. Sequentially by 1 ,2 ,3,4 Dont visit the forum in middle of the test (or the course for that matter). Test the following:- TEST 1 Course group mode : visible course groupmode force : true forum groupmode: doesnt matter Student 1 should see all posts in my home page Student 2 should see all posts in my home page Student 3 should see all posts in my home page Student 4 should see all posts in my home page Make sure post count is right Go to the course page and make sure recent activity block only display posts in his/her group TEST 2 Course group mode : SEPARATE course groupmode force : true forum groupmode: doesnt matter Student 1 should see only student 2's posts in my home page Student 2 should see only no posts in my home page Student 3 should see only student 4's posts in my home page Student 4 should see only no posts in my home page Make sure post count is right Go to the course page and make sure recent activity block only display posts in his/her group TEST 3 Course group mode : doesn't matter course groupmode force : false forum groupmode: SEPARATE Student 1 should see only student 2's posts in my home page Student 2 should see only no posts in my home page Student 3 should see only student 4's posts in my home page Student 4 should see only no posts in my home page Make sure post count is right Go to the course page and make sure recent activity block only display posts in his/her group TEST 4 Course group mode : doesn't matter course groupmode force : false forum groupmode: visisble Student 1 should see all posts in my home page Student 2 should see all posts in my home page Student 3 should see all posts in my home page Student 4 should see all posts in my home page Make sure post count is right Go to the course page and make sure recent activity block only display posts in his/her group TEST 5 Course group mode : doesn't matter course groupmode force : false forum groupmode: no groups Student 1 should see all posts in my home page Student 2 should see all posts in my home page Student 3 should see all posts in my home page Student 4 should see all posts in my home page Make sure post count is right Go to the course page and make sure recent activity block only display posts in his/her group TEST 6 Course group mode : NOGROUPS course groupmode force : true forum groupmode: doesn't matter Student 1 should see all posts in my home page Student 2 should see all posts in my home page Student 3 should see all posts in my home page Student 4 should see all posts in my home page Make sure post count is right Go to the course page and make sure recent activity block only display posts in his/her group Note:- All posts means all posts made after the user last visited the course, expect the user's own posts which are never shown
