+  Scenario Outline: Grade report should only show participation groups
+    Given I am on the "<workshop>" "workshop activity" page logged in as "teacher1"
+    And I follow "Switch to the next phase"
+    And I press "Continue"
+    And I should see "All participants" in the "<mode> groups" "select"
+    And I should see "Group 1" in the "<mode> groups" "select"
+    And I should see "Group 2" in the "<mode> groups" "select"
+    And I should not see "Group 3" in the "<mode> groups" "select"
+    And the field "<mode> groups" matches value "All participants"
+    And I should see "User1G1"
+    And I should see "User2G2"
+    And I should see "User3None"
+    And I should see "User4NPgroup"
+    When I select "Group 1" from the "<mode> groups" singleselect
+    Then I should see "User1G1"
+    And I should not see "User2G2"
+    And I should not see "User3None"
+    And I should not see "User4NPgroup"
+
+    Examples:
+      | workshop  | mode     |
+      | workshop1 | Separate |
+      | workshop2 | Visible  |
+
