+
+  @javascript
+  Scenario: Teacher can override assignment deadlines
+    Given I navigate to "Submissions" in current page administration
+    Then the following should exist in the "generaltable" table:
+      | First name    | Due date                           |
+      | Sam1 Student1 | Friday, 3 January 2031, 8:00 AM    |
+      | Sam2 Student2 | Thursday, 2 January 2020, 8:00 AM  |
+      | Sam3 Student3 | Wednesday, 1 January 2020, 8:00 AM |
+
+  @javascript
+  Scenario: Students see overridden assignment deadlines
+    When I am on the "Test assignment name" Activity page logged in as student1
+    Then I should see "Due: Friday, 3 January 2031, 8:00"
+    And I am on the "Test assignment name" Activity page logged in as student2
+    And I should see "Due: Thursday, 2 January 2020, 8:00"
+    And I am on the "Test assignment name" Activity page logged in as student3
+    And I should see "Due: Wednesday, 1 January 2020, 8:00"
+
+  @javascript
+  Scenario: Teacher can reorder group overrides
+    Given I am on the "Test assignment name" Activity page logged in as teacher1
+    And I navigate to "Overrides" in current page administration
+    And I select "Group overrides" from the "jump" singleselect
+    When I click on "Move down" "link" in the "Group 1" "table_row"
+    # Verify the position of Group 1 and Group 2 has swapped in the list.
+    Then the following should exist in the "generaltable" table:
+      | Group   | Overrides |               -3-                  |
+      | Group 2 | Due date  | Thursday, 2 January 2020, 8:00 AM  |
+      | Group 1 | Due date  | Wednesday, 1 January 2020, 8:00 AM |
+    And I navigate to "Submissions" in current page administration
+    Then "Sam3 Student3" row "Due date" column of "submissions" table should contain "Thursday, 2 January 2020, 8:00"
+
+  @javascript
+  Scenario: Inactive override due to hidden assignment
+    Given I am on "Course 1" course homepage with editing mode on
+    And I open "Test assignment name" actions menu
+    When I choose "Hide" in the open action menu
+    And I am on the "Test assignment name" Activity page
+    And I navigate to "Overrides" in current page administration
+    Then I should see "* This override is inactive because the user's access to the activity is restricted. This can be due to group or role assignments, other access restrictions, or the activity being hidden."
+    And "Edit" "icon" should exist in the "Sam1 Student1" "table_row"
+    And "copy" "icon" should exist in the "Sam1 Student1" "table_row"
+    And "Delete" "icon" should exist in the "Sam1 Student1" "table_row"
