如何使用jest对componentWillReceiveProps(nextProps)进行单元测试？

npm install --save-dev jest babel-jest @babel/preset-env @babel/preset-react react-test-renderer

import React from 'react';
import { shallow } from 'enzyme';
import Component from './Component';

describe('Component', () => {
  it('should update state correctly when receiving new props', () => {
    const wrapper = shallow(<Component />);
    const instance = wrapper.instance();

    // 模拟传入新的props
    const nextProps = {
      prop1: 'new value',
      prop2: 123,
    };

    // 调用componentWillReceiveProps方法
    instance.componentWillReceiveProps(nextProps);

    // 断言state是否正确更新
    expect(instance.state.prop1).toEqual(nextProps.prop1);
    expect(instance.state.prop2).toEqual(nextProps.prop2);
  });
});

npx jest
