Same name and namespace in other branches

1. 9 core/modules/views/tests/src/Kernel/Plugin/SqlQueryTest.php \Drupal\Tests\views\Kernel\Plugin\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.
