Concise code using ChessHelper

The ChessHelper class provides methods allowing to directly apply a move on a given position, returning the destination position. This is used to avoid having to apply all board updates in a nested loop.

@Autowired
private ChessRules chessRules;

@Autowired
private PgnMarshaller pgnMarshaller;

@Test
public void testGame() throws PgnMoveException, IllegalMoveException {
    String[] history = {"f3", "e5", "g4", "Qh4"};
    ChessPosition position = chessRules.getInitialPosition();

    for ( String pgnMove: history) {
        ChessMovePath path = pgnMarshaller.convertPgnToMove(position, pgnMove);
        position = ChessHelper.applyMove(chessRules, position, path);
    }

    System.out.println(position);
}

This will output:
