Feature: Gradebook calculations for natural weights normalisation before the fix 20150619
  In order to make sure the grades are not changed after upgrade
  As a teacher
  I need to be able to freeze gradebook calculations

  Background:
    Given the following "courses" exist:
      | fullname | shortname | category | groupmode |
      | Course 1 | C1 | 0 | 1 |
    And gradebook calculations for the course "C1" are frozen at version "20150619"
    And the following "users" exist:
      | username | firstname | lastname | email | idnumber |
      | teacher1 | Teacher | 1 | teacher1@example.com | t1 |
      | student1 | Student | 1 | student1@example.com | s1 |
    And the following "course enrolments" exist:
      | user | course | role |
      | teacher1 | C1 | editingteacher |
      | student1 | C1 | student |
    And the following "grade categories" exist:
      | fullname | course |
      | Sub category 1 | C1 |
    And the following "activities" exist:
      | activity | course | idnumber | name | intro | grade |
      | assign | C1 | a1 | Test assignment one | Submit something! | 300 |
      | assign | C1 | a2 | Test assignment two | Submit something! | 100 |
      | assign | C1 | a3 | Test assignment three | Submit something! | 150 |
      | assign | C1 | a4 | Test assignment four | Submit nothing! | 150 |
    And the following "activities" exist:
      | activity | course | idnumber | name | intro | gradecategory | grade |
      | assign | C1 | a5 | Test assignment five | Submit something! | Sub category 1 | 20 |
      | assign | C1 | a6 | Test assignment six | Submit something! | Sub category 1 | 10 |
      | assign | C1 | a7 | Test assignment seven | Submit nothing! | Sub category 1 | 15 |
    And I log in as "teacher1"
    And I am on "Course 1" course homepage
    And I navigate to "Setup > Gradebook setup" in the course gradebook

  Scenario: Grade items weights are normalised when all grade item weights are overridden (sum exactly 100). Extra credit is set to zero (before the fix 20150619).
    When I set the following settings for grade item "Test assignment seven":
      | Extra credit | 1 |
    And the field "Weight of Test assignment five" matches value "66.667"
    And the field "Weight of Test assignment six" matches value "33.333"
    And the field "Weight of Test assignment seven" matches value "50.0"
    And I set the field "Override weight of Test assignment five" to "1"
    And I set the field "Override weight of Test assignment six" to "1"
    And I set the field "Weight of Test assignment five" to "60"
    And I set the field "Weight of Test assignment six" to "40"
    And I press "Save changes"

    Then I should see "Your weights have been adjusted to total 100."
    And the field "Weight of Test assignment five" matches value "60.000"
    And the field "Weight of Test assignment six" matches value "40.000"
    And the field "Weight of Test assignment seven" matches value "0.0"
    # The weight of "seven" should be 15/30=50% (15 is the maxgrade for "seven" and 30 are max grades for this category (max grade of "five" plus max grade of "six")
    And I reset weights for grade category "Sub category 1"
    And the field "Weight of Test assignment five" matches value "66.667"
    And the field "Weight of Test assignment six" matches value "33.333"
    And the field "Weight of Test assignment seven" matches value "50.0"
