### Question:
OnmsTopologyProvider extends AbstractTopologyProvider implements GraphProvider { @Override public void load(String filename) { OnmsMap map = getMap(Integer.parseInt(filename)); List<Vertex> vertices = getVertex(map.getId(),null); List<Edge> edges = getEdges(vertices); clearVertices(); addVertices(vertices.toArray(new Vertex[] {})); clearEdges(); addEdges(edges.toArray(new Edge[] {})); } OnmsTopologyProvider(); OnmsMapDao getOnmsMapDao(); void setOnmsMapDao(OnmsMapDao onmsMapDao); OnmsMapElementDao getOnmsMapElementDao(); void setOnmsMapElementDao(OnmsMapElementDao onmsMapElementDao); DataLinkInterfaceDao getDataLinkInterfaceDao(); void setDataLinkInterfaceDao(DataLinkInterfaceDao dataLinkInterfaceDao); @Override void save(); void save(String filename); @Override void refresh(); @Override void load(String filename);  }### Answer:
@Test public void testLoad1() { m_topologyProvider.load("1"); }
@Test public void testLoad2() { m_topologyProvider.load("2"); }
