从2个现有对象创建新对象

// 定义一个构造函数
function Person(name, age) {
  this.name = name;
  this.age = age;
}

// 使用构造函数创建新对象
var person1 = new Person("John", 25);
var person2 = new Person("Jane", 30);

// 定义一个类
class Person {
  String name;
  int age;
  
  // 构造方法
  public Person(String name, int age) {
    this.name = name;
    this.age = age;
  }
}

// 使用类创建新对象
Person person1 = new Person("John", 25);
Person person2 = new Person("Jane", 30);

import unittest

# 定义一个测试类
class MyTestCase(unittest.TestCase):
    def test_something(self):
        # 测试代码
        self.assertEqual(1 + 1, 2)

# 创建测试对象
my_test = MyTestCase()
