### Question:
DataSetLoaderProvider implements LoaderProvider<Graph<Node, Edge>> { @Override public DataSetLoader<Graph<Node, Edge>> yamlLoader() { throw new UnsupportedDataSetFormatException("YAML data sets are not supportred for Neo4j"); } DataSetLoaderProvider(final GraphElementFactory graphElementFactory); @Override DataSetLoader<Graph<Node, Edge>> xmlLoader(); @Override DataSetLoader<Graph<Node, Edge>> yamlLoader(); @Override DataSetLoader<Graph<Node, Edge>> jsonLoader(); @Override DataSetLoader<Graph<Node, Edge>> csvLoader(); @Override DataSetLoader<Graph<Node, Edge>> xlsLoader();  }### Answer:
@Test(expected = UnsupportedDataSetFormatException.class) public void testYamlLoaderNotSupported() { LOADER_PROVIDER.yamlLoader(); }
