对基本的井字棋游戏进行自动化测试

Question

正如标题所说，我正在为 tic tac toe 游戏制作自动化测试用例，但是我在尝试测试的方法中使用扫描仪 nextInt 方法，我只是不明白如何使我的测试用例自动填充输入，而不是比程序询问用户。下面是两个方法：

主类方法：

public static void playGame(String playerOne, String playerTwo, char[][] gameBoard, int playerNum, Scanner input) {
        int moveSelected = 0;
        while (moveSelected >= 10 || moveSelected <= 0) {
            moveSelected = 0;
            try {
                if (playerNum == 1) {
                    System.out.println(playerOne + " please input your spot selection(1-9)");
                } else {
                    System.out.println(playerTwo + " please input your spot selection(1-9)");
                }
                moveSelected = input.nextInt();
            }
            catch(InputMismatchException e){
                System.err.println("Wrong input! Integer Values Only.");
                input.next();
            }
        }

        playerMove(moveSelected, playerNum, gameBoard);
        displayBoard(gameBoard);
    }

测试方法：

public void testplayGame(){
        Scanner input = new Scanner(System.in);
        char[][] gameBoard = {{' ', '|', ' ', '|', ' '},
                {'-', '+', '-', '+', '-'},
                {' ', '|', ' ', '|', ' '},
                {'-', '+', '-', '+', '-'},
                {' ', '|', ' ', '|', ' '}};
        for(int i =1; i<10;i++) {
            assertEquals(fstTest.playGame("p1","p2",gameBoard,1,input));
        }
    }
