Feature: Teachers can't change status variables to have empty acronyms or descriptions
    In order to update status variables
    As a teacher
    I need to see an error notice below each acronym / description that I try to set to be empty

    Background:
        Given the following "courses" exist:
            | fullname | shortname | summary | category |
            | Course 1 | C101      | Prove the attendance activity settings works | 0 |
        And the following "users" exist:
            | username    | firstname | lastname |
            | student1    | Sam       | Student  |
            | teacher1    | Teacher   | One      |
        And the following "course enrolments" exist:
            | user        | course | role    |
            | student1    | C101   | student |
            | teacher1    | C101   | editingteacher |
        And I log in as "teacher1"
        And I follow "Course 1"
        And I turn editing mode on
        And I add a "Attendance" to section "1" and I fill the form with:
            | Name        | Attendancepreftest       |
        And I follow "Attendancepreftest"
        And I follow "Settings"
