React:这个Pomodoro时钟怎么能通过‘`freecodecamp测试12和13’？

import React, { useState, useEffect } from "react";

const PomodoroClock = () => {
  const [workTime, setWorkTime] = useState(25 * 60); // 工作时间，默认25分钟
  const [breakTime, setBreakTime] = useState(5 * 60); // 休息时间，默认5分钟
  const [timeLeft, setTimeLeft] = useState(workTime); // 倒计时剩余时间
  const [isWorking, setIsWorking] = useState(true); // 是否处于工作状态

  useEffect(() => {
    // 每秒更新倒计时剩余时间
    const timer = setInterval(() => {
      setTimeLeft((prevTime) => prevTime - 1);
    }, 1000);

    // 当倒计时剩余时间为0时，根据当前状态切换到相应的时间
    if (timeLeft === 0) {
      if (isWorking) {
        setTimeLeft(breakTime);
      } else {
        setTimeLeft(workTime);
      }
      setIsWorking((prevState) => !prevState); // 切换工作状态
    }

    // 组件卸载时清除定时器
    return () => clearInterval(timer);
  }, [timeLeft, isWorking, workTime, breakTime]);

  // 格式化倒计时剩余时间为mm:ss格式
  const formatTime = (time) => {
    const minutes = Math.floor(time / 60).toString().padStart(2, "0");
    const seconds = (time % 60).toString().padStart(2, "0");
    return `${minutes}:${seconds}`;
  };

  return (
    <div>
      <h1>{isWorking ? "工作时间" : "休息时间"}</h1>
      <h2>{formatTime(timeLeft)}</h2>
    </div>
  );
};

export default PomodoroClock;
