  @javascript
  Scenario: Forum rescale grade should not be possible when users are graded
    Given I am on the "Test forum name" "forum activity editing" page logged in as teacher1
    And I expand all fieldsets
    And I set the field "Ratings > Aggregate type" to "Count of ratings"
    And I set the field "Ratings > Type" to "Point"
    And I press "Save and return to course"
    And I am on the "Test forum name" "forum activity" page
    And I follow "Discussion subject"
    And I set the field "rating" to "30"
    When I am on the "Test forum name" "forum activity editing" page
    And I expand all fieldsets
    Then the "Maximum grade" "field" should be disabled
