getDefaultAmountOfStepsPerRun()

ILIAS\Test\Setup\MoveTestSettingsMigration::getDefaultAmountOfStepsPerRun

(

)

Tell the default amount of steps to be executed for one run of the migration.

Return Migration::INFINITE if all units should be migrated at once.

Implements ILIAS\Setup\Migration.

Definition at line 38 of file MoveTestSettingsMigration.php.

                                                   : int
    {
        return 100;
    }

getLabel()

ILIAS\Test\Setup\MoveTestSettingsMigration::getLabel

(

)

Returns

string - a meaningful and concise description for your migration.

Implements ILIAS\Setup\Migration.

Definition at line 33 of file MoveTestSettingsMigration.php.

                              : string
    {
        return 'Migrate test settings from tst_tests to tst_test_settings';
    }

getPreconditions()

ILIAS\Test\Setup\MoveTestSettingsMigration::getPreconditions

(

Environment

$environment

)

Objectives the migration depend on.

Exceptions

UnachievableException

if the objective is not achievable

Returns

Objective[]

    {
        return [new \ilDatabaseInitializedObjective()];
    }

getRemainingAmountOfSteps()

ILIAS\Test\Setup\MoveTestSettingsMigration::getRemainingAmountOfSteps

(

)

Count up how many "things" need to be migrated.

This helps the admin to decide how big he can create the steps and also how long a migration takes

Implements ILIAS\Setup\Migration.

Definition at line 88 of file MoveTestSettingsMigration.php.

    {
        $result = $this->db->query("SELECT COUNT(test_id) AS cnt FROM tst_tests WHERE settings_id IS NULL");
        return (int) $this->db->fetchObject($result)->cnt;
    }

prepare()

ILIAS\Test\Setup\MoveTestSettingsMigration::prepare

(

Environment

$environment

)

Prepare the migration by means of some environment.

This is not supposed to modify the environment, but will be run to prime the migration object to run step and getRemainingAmountOfSteps afterwards.

Implements ILIAS\Setup\Migration.
