    FoldingStateDescriptor<?, ?> descrIntercepted = (FoldingStateDescriptor<?, ?>) descriptorCapture.get();
    TypeSerializer<?> serializer = descrIntercepted.getSerializer();
    // check that the Path class is really registered, i.e., the execution config was applied
    assertTrue(serializer instanceof KryoSerializer);
    assertTrue(((KryoSerializer<?>) serializer).getKryo().getRegistration(Path.class).getId() > 0);
}
