Javascript 有我必须为之编写代码的预测试。可以让代码工作，但无法通过测试

我还是个新手。三个月学习javascript。因此，在写入方向上进行任何推送都会有帮助

所以我现在正在做一项作业，这是我们第一次做测试。测试是预先为我们准备的，我们只需要编写代码并通过测试。我在通过测试时遇到了问题，即使我的代码正在执行测试所检查的内容

const inquirer = require('inquirer');


class Employee {

    constructor(name, id, email) {
        this.name = name;
        this.id = id;
        this.email = email;
    }

    getName() {
        return inquirer.prompt([
            {
            type: 'input',
            name: 'name',
            message: "What is the employee's name?"
            }
        ]).then(answers => {
            this.name = answers.name;
            this.getId();
        })
    }

    getId() {
        return inquirer.prompt([
            {
                type: 'number',
                name: 'id',
                message: "What is the employee's ID?"
            }
        ]).then(answers => {
            this.id = answers.id;
            this.getEmail();
        })
    }

    getEmail(){
        return inquirer.prompt([
            {
                type: 'input',
                name: 'email',
                message: "What is the employee's email?"
            }
        ]).then(answers => {
            this.email = answers.email;
            this.getRole();
        })
    }

    getRole(){
        this.role = 'employee'
        console.log(this)
    }
}

const e = new Employee();
e.getName();

测试是这样的

const Employee = require("../lib/Employee");

test("Can instantiate Employee instance", () => {
  const e = new Employee();
  expect(typeof(e)).toBe("object");
});

test("Can set name via constructor arguments", () => {
  const name = "Alice";
  const e = new Employee(name);
  expect(e.name).toBe(name);
});

test("Can set id via constructor argument", () => {
  const testValue = 100;
  const e = new Employee("Foo", testValue);
  expect(e.id).toBe(testValue);
});

test("Can set email via constructor argument", () => {
  const testValue = "test@test.com";
  const e = new Employee("Foo", 1, testValue);
  expect(e.email).toBe(testValue);
});

test("Can get name via getName()", () => {
  const testValue = "Alice";
  const e = new Employee(testValue);
  expect(e.getName()).toBe(testValue);
});

test("Can get id via getId()", () => {
  const testValue = 100;
  const e = new Employee("Foo", testValue);
  expect(e.getId()).toBe(testValue);
});

test("Can get email via getEmail()", () => {
  const testValue = "test@test.com";
  const e = new Employee("Foo", 1, testValue);
  expect(e.getEmail()).toBe(testValue);
});

test("getRole() should return \"Employee\"", () => {
  const testValue = "Employee";
  const e = new Employee("Alice", 1, "test@test.com");
  expect(e.getRole()).toBe(testValue);
});

当我运行代码时，它会创建一个包含所有问题答案的对象，但测试只会返回失败的结果，因为雇员不是构造函数

有人给了我一些提示或方法来引导我走错方向吗？

我不知道你是否明白，但我也有同样的问题。问题是您必须添加module.exports=Employee； 否则不能在其他文件中使用。 希望这有帮助
