如何检查酶jest测试用例中的对象值

const expectedObject = { name: 'John', age: 25 };
const actualObject = { name: 'John', age: 25 };
expect(actualObject).toEqual(expectedObject);

const person = { name: 'John', age: 25 };
expect(person).toHaveProperty('name');
expect(person).toHaveProperty('age', 25);

const expectedPartialObject = { name: 'John' };
const actualObject = { name: 'John', age: 25 };
expect(actualObject).toMatchObject(expectedPartialObject);

const actualObject = { name: 'John', age: 25 };
expect(actualObject).toMatchSnapshot();

expect.extend({
  toBeYoungPerson(received) {
    const { name, age } = received;
    const isYoung = age < 30;
    if (isYoung) {
      return {
        message: () => `expected ${name} to be a young person`,
        pass: true,
      };
    } else {
      return {
        message: () => `expected ${name} to be an old person`,
        pass: false,
      };
    }
  },
});

const person = { name: 'John', age: 25 };
expect(person).toBeYoungPerson();
