    // Given
    final ForEach<ElementSeed, Iterable<String>> op = new ForEach.Builder<ElementSeed, Iterable<String>>().input(Collections.singletonList(new EdgeSeed("doesNotExist", "doesNotExist", true))).operation(new OperationChain.Builder().first(new ToSingletonList<EntitySeed>()).then(new GetElements()).then(new ToCsv.Builder().includeHeader(false).generator(new CsvGenerator.Builder().vertex("vertex").destination("dest").build()).build()).build()).build();
    // When
    final List<Iterable<String>> results = Lists.newArrayList(graph.execute(op, getUser()));
    // Then
    assertThat(results).hasSize(1);
