如何使此终端应用程序通过节点测试？

所以这是一个小型的终端游戏，剪刀石头布的，我需要编写其余代码的帮助，以便它可以通过我的节点测试。我已经能够编写代码并输入hand1和hand2的决策，并获得显示谁获胜的结果，但是当我运行它们时，它似乎并没有通过节点测试。

节点测试将“领带”检测为正确的，但未检测出获胜的手或擦洗输入为正确的，但是当我在终端中使用它时，所有操作均有效。这是节点测试所说的图像

需要重写的代码在下面的函数rockPaperScissors（hand1，hand2）中

    'use strict';

const assert = require('assert');
const readline = require('readline');
const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});


function rockPaperScissors(hand1, hand2) {

  if (hand1 === hand2) {
    return "It's a tie!";
  } else if (hand1 === 'rock') {
    if (hand2 === 'paper') {
      return "Hand two wins!";
    } else if (hand2 === 'scissors') {
      return "Hand one wins!";
    } 
  }

  if (hand1 === 'paper') {
    if (hand2 === 'rock') {
      return "Hand one wins!";
    } else if (hand2 === 'scissors') {
      return "Hand two wins!";
    }
  }

  if (hand1 === 'scissors') {
    if (hand2 === 'paper') {
      return "Hand one wins!";
    } else if (hand2 === 'rock') {
      return "Hand two wins!";
    }
  }




}











function getPrompt() {
  rl.question('hand1: ', (answer1) => {
    rl.question('hand2: ', (answer2) => {
      console.log( rockPaperScissors(answer1, answer2) );
      getPrompt();
    });
  });
}

// Tests

if (typeof describe === 'function') {

  describe('#rockPaperScissors()', () => {
    it('should detect a tie', () => {
      assert.equal(rockPaperScissors('rock', 'rock'), "It's a tie!");
      assert.equal(rockPaperScissors('paper', 'paper'), "It's a tie!");
      assert.equal(rockPaperScissors('scissors', 'scissors'), "It's a tie!");
    });
    it('should detect which hand won', () => {
      assert.equal(rockPaperScissors('rock', 'paper'), "Hand two wins!");
      assert.equal(rockPaperScissors('paper', 'scissors'), "Hand two wins!");
      assert.equal(rockPaperScissors('rock', 'scissors'), "Hand one wins!");
    });
    it('should scrub input to ensure lowercase with "trim"ed whitepace', () => {
      assert.equal(rockPaperScissors('rOcK', ' paper '), "Hand two wins!");
      assert.equal(rockPaperScissors('Paper', 'SCISSORS'), "Hand two wins!");
      assert.equal(rockPaperScissors('rock ', 'sCiSsOrs'), "Hand one wins!");
    });
  });
} else {

  getPrompt();

}

您必须修剪和小写hand1和hand2参数的值：

function rockPaperScissors(hand1, hand2) {
  hand1 = hand1.trim().toLowerCase();
  hand2 = hand2.trim().toLowerCase();
  ...

该装饰功能从文本中删除多余的空格。toLowerCase函数将所有字符转换为小写。

现在，您的rockPaperScissors函数如下所示：



function rockPaperScissors(hand1, hand2) {
  hand1 = hand1.trim().toLowerCase();
  hand2 = hand2.trim().toLowerCase();

  if (hand1 === hand2) {
    return "It's a tie!";
  } else if (hand1 === 'rock') {
    if (hand2 === 'paper') {
      return "Hand two wins!";
    } else if (hand2 === 'scissors') {
      return "Hand one wins!";
    } 
  }

  if (hand1 === 'paper') {
    if (hand2 === 'rock') {
      return "Hand one wins!";
    } else if (hand2 === 'scissors') {
      return "Hand two wins!";
    }
  }

  if (hand1 === 'scissors') {
    if (hand2 === 'paper') {
      return "Hand one wins!";
    } else if (hand2 === 'rock') {
      return "Hand two wins!";
    }
  }




}
