+
+  Scenario Outline: Users should see their own participation groups in "separate groups" mode, and all
+  participation groups in "visible groups" mode.
+    Given I am on the "<choice>" "choice activity" page logged in as "<user>"
+    Then I <all> "All participants"
+    And I <G1> "Group 1"
+    And I <G2> "Group 2"
+    And I should not see "Group 3"
+
+    Examples:
+      | choice  | user     | all            | G1             | G2             |
+      | choice1 | teacher1 | should see     | should see     | should see     |
+      | choice1 | user1    | should not see | should see     | should not see |
+      | choice1 | user2    | should not see | should not see | should see     |
