Feature: Uniqueness The course custom fields can be mandatory or not
  In order to make users required to fill a custom field
  As a manager
  I can change the uniqueness of the fields

  Background:
    Given the following "custom field categories" exist:
      | name              | component   | area   | itemid |
      | Category for test | core_course | course | 0      |
    Given the following "users" exist:
      | username | firstname | lastname | email                |
      | teacher1 | Teacher   | 1        | teacher1@example.com |
    And the following "courses" exist:
      | fullname | shortname | format |
      | Course 1 | C1        | topics |
      | Course 2 | C2        | topics |
    And the following "course enrolments" exist:
      | user     | course | role           |
      | teacher1 | C1     | editingteacher |
      | teacher1 | C2     | editingteacher |

      | Name        | Test field |
