Feature: We can use natural aggregation and weights will be normalised to a total of one hundred
  In order to override weights
  As a teacher
  I need to add assessments to the gradebook.

  Background:
    Given the following "courses" exist:
      | fullname | shortname | category | groupmode |
      | Course 1 | C1 | 0 | 1 |
    And the following "users" exist:
      | username | firstname | lastname | email | idnumber |
      | teacher1 | Teacher | 1 | teacher1@asd.com | t1 |
      | student1 | Student | 1 | student1@asd.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 |
