出于某種原因，我得到：
第一次測驗通過：“愛所有人”
第二次測驗失敗：預期：“十五愛”收到：“十五愛全愛”
據我了解，我需要使用 afterEach 來拆除原始配置。我試過這個，但它似乎沒有“擦除”totalScore。
謝謝你的幫助！
測驗檔案：
const Tennis = require("../src/index");
describe("Tennis game", () => {
let tennis;
beforeEach(() => {
tennis = new Tennis();
});
afterEach(() => {
tennis.resetGame();
});
const scoreShouldBe = (expected) => {
tennis.getScore();
expect(tennis.totalScore).toBe(expected);
};
test("Love all", () => {
scoreShouldBe("Love all");
});
test("Fifteen love", () => {
tennis.firstPlayerScore();
scoreShouldBe("Fifteen love");
});
});
Index.js 檔案：
class Tennis {
constructor() {
this.firstPlayerScoreTimes = 0;
this.totalScore = "";
}
getScore() {
if (this.firstPlayerScoreTimes === 1) {
this.totalScore = "Fifteen love";
}
this.totalScore = "Love all";
}
firstPlayerScore() {
this.firstPlayerScoreTimes ;
}
resetGame() {
this.totalScore = "";
}
}
module.exports = Tennis;

=在類中的getScore方法中洗掉，Tennis因為它將新字串添加到舊字串中。
class Tennis {
constructor() {
this.firstPlayerScoreTimes = 0;
this.totalScore = "";
}
getScore() {
if (this.firstPlayerScoreTimes === 1) {
this.totalScore = "Fifteen love";
}
this.totalScore = "Love all";
}
firstPlayerScore() {
this.firstPlayerScoreTimes ;
}
resetGame() {
this.totalScore = "";
}
}
module.exports = Tennis;

您的測驗運行良好，您需要更新的是您的生產代碼。
當前邏輯，當firstPlayerScoreTimes為 1 時，您將分數設定為Fifteen love并將Love all字串附加到分數。我想這不是你的要求。讓我們更新getScore函式：
getScore() {
if (this.firstPlayerScoreTimes === 1) {
return this.totalScore = "Fifteen love"; // stop, that's enough
}
this.totalScore = "Love all";
}
