rerender可以这样做
如果你想在测试中更新一个渲染组件的props，这个函数可以用来更新渲染组件的props。
例如：

import { render, screen } from '@testing-library/react';
import '@testing-library/jest-dom';
import React from 'react';

const Button = (props: React.ButtonHTMLAttributes<HTMLButtonElement>) => <button {...props}>click me</button>

describe('76118663', () => {
  let rerender: ReturnType<typeof render>['rerender'];
  const props: React.ButtonHTMLAttributes<HTMLButtonElement> = { type: 'button' };
  beforeEach(() => {
    rerender = render(<Button {...props} />).rerender;
  });
  test('should override button disabled prop', () => {
    expect(screen.queryByRole('button')).toBeEnabled();
    rerender(<Button {...props} disabled />);
    expect(screen.queryByRole('button')).toBeDisabled();
  });

  test('should override button type prop and reset disabled prop', () => {
    rerender(<Button {...props} type='submit' />);
    expect(screen.queryByRole('button')).toBeEnabled();
    expect(screen.queryByRole('button')).toHaveAttribute('type', 'submit');
  })
})

测试结果：
