- * Fix orphaned calendar events that were broken by MDL-67494.
- *
- * This script will look for all the calendar events which userids
- * where broken by a wrong upgrade step, affecting to Moodle 3.9.5
- * and up.
- *
- * It performs checks to both:
- *    a) Detect if the site was affected (ran the wrong upgrade step).
- *    b) Look for orphaned calendar events, categorising them as:
- *       - standard: site / category / course / group / user events
- *       - subscription: events created via subscriptions.
- *       - action: normal action events, created to show common important dates.
- *       - override: user and group override events, particular, that some activities support.
- *       - custom: other events, not being any of the above, common or particular.
- * By specifying it (--fix) try to recover as many broken events (missing userid) as
- * possible. Standard, subscription, action, override events in core are fully supported but
- * override or custom events should be fixed by each plugin as far as there isn't any standard
- * API (plugin-wise) to launch a rebuild of the calendar events.

-@tool @tool_customlang
-Feature: Within a moodle instance, an administrator should be able to modify langstrings for the entire Moodle installation.
-  In order to change langstrings in the adminsettings of the instance,
-  As an admin
-  I need to be able to access and change values in the the language customisation of the language pack.
-
-  Background:
-    # This is a very slow running test and on slow databases can take minutes to complete.
-    Given I mark this test as slow setting a timeout factor of 4
-
-    And I log in as "admin"
-    And I navigate to "Language > Language customisation" in site administration
-    And I set the field "lng" to "en"
-    And I press "Open language pack for editing"
-    And I press "Continue"
-    And I set the field "Show strings of these components" to "moodle.php"
-    And I set the field "String identifier" to "administrationsite"
-    And I press "Show strings"
-    And I set the field "core/administrationsite" to "Custom string example"
-
-  @javascript
-  Scenario: Edit an string but don't save it to lang pack.
-    When I press "Apply changes and continue editing"
-    Then I should see "Site administration" in the "page-header" "region"
-    And I should not see "Custom string example" in the "page-header" "region"
-
-  @javascript
-  Scenario: Customize an string as admin and save it to lang pack.
-    Given I press "Save changes to the language pack"
-    And I should see "There are 1 modified strings."
-    When I click on "Continue" "button"
-    Then I should see "Custom string example" in the "page-header" "region"
-    And I should not see "Site administration" in the "page-header" "region"
