function LoggingTest::testEnableLogging

Tests that we can log the existence of a query.

This test is only marked as legacy to be able to test the deprecated db_query function().

@group legacy

@expectedDeprecationMessage db_query() is deprecated in drupal:8.0.0. It will be removed before drupal:9.0.0. Instead, get a database connection injected into your service from the container and call query() on it. For example, $injected_database->query($query, $args, $options).
