public function DatabaseLegacyTest::testDbFieldNames in Drupal 8

Tests deprecation of the db_field_names() function.

@expectedDeprecation db_field_names() is deprecated in drupal:8.0.0. It will be removed from drupal:9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call fieldNames() on it. For example, $injected_database->schema()->fieldNames($fields).
