function SqlQueryTest::testGetConnection

Tests the method \Drupal\views\Plugin\views\query\Sql::getConnection().

@covers \Drupal\views\Plugin\views\query\Sql::getConnection

This needs to be a kernel test because the tested method uses the method \Drupal\Core\Database\Database::getConnection() which is a 'final' method and therefore cannot be mocked.
