### Question:
Astar { public static Heuristic createHeuristicManhattan(int minimumCost) { return new HeuristicManhattan(minimumCost); } 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 testCreateHeuristicManhattan() { assertEquals(HeuristicManhattan.class, Astar.createHeuristicManhattan(1).getClass()); }
