### Question:
Astar { public static PathFinder createPathFinder(MapTile map, int maxSearchDistance, Heuristic heuristic) { return new PathFinderImpl(map, maxSearchDistance, heuristic); } private  Astar(); static PathFinder createPathFinder(MapTile map, int maxSearchDistance, Heuristic heuristic); static Heuristic createHeuristicClosest(); static Heuristic createHeuristicClosestSquared(); static Heuristic createHeuristicManhattan(int minimumCost);  }### Answer:
@Test void testCreatePathFinder() { final MapTileGame map = new MapTileGame(); map.addFeature(new MapTileGroupModel()); map.addFeature(new MapTilePathModel()); assertNotNull(Astar.createPathFinder(map, 1, new HeuristicClosest())); }
