使用react-test-renderer测试异步componentDidMount()

import React from 'react';
import { render } from 'react-test-renderer';
import MyComponent from './MyComponent';

test('异步 componentDidMount() 测试', () => {
  const component = render(<MyComponent />);
});

test('异步 componentDidMount() 测试', () => {
  const component = render(<MyComponent />);
  component.getInstance().componentDidMount(); // 模拟异步操作完成后的状态变化
  // 执行断言或其他验证
});

test('异步 componentDidMount() 测试', () => {
  const component = render(<MyComponent />);
  component.getInstance().componentDidMount();
  expect(component.toJSON()).toMatch('Hello World');
});
