@Override
public GraphTraversalSource traversal(final Graph graph) {
    if ((Boolean) graph.configuration().getProperty("skipTest"))
        return graph.traversal();
        //throw new VerificationException("This test current does not work with Gremlin-Python", EmptyTraversal.instance());

        return g.withStrategies(PartitionStrategy.build()
                .partitionKey(key)
                .readPartitions(query.get("p")) // TODO This should be a query.get("p").toArray(EMPTY)

        List<String> labels = Splitter.on(",").omitEmptyStrings().splitToList(query.get("l"));
        if (!labels.isEmpty()) {
            String label = labels.get(0);
            String[] otherLabels = labels.subList(1, labels.size()).toArray(EMPTY);

                    .vertices(hasLabel(label, otherLabels))
                    .create());
        }
    }

    // Use "?m=" to filter to metadata only
    if (query.containsKey("m")) {
        String metadataLabel = g.getGraph().configuration().getString("bdio.metadataLabel");
        return g.withStrategies(SubgraphStrategy.build()
