Reactjs 如何编写快速刷新测试

如何编写测试以查看快速刷新重新加载钩子/组件（或模拟相同效果）时钩子/组件会发生什么情况

现在我正在使用

@测试库/react hooks

测试钩子

import { act, renderHook } from '@testing-library/react-hooks';
it('should return undefined', () => {
  const useV1 = () => {
    const [count] = useState(1);
    const value = useMyHook(count);
    return { value };
  }
  const useV2 = () => {
    const [count] = useState(5);
    const value = useMyHook(count);
    return { value };
  }

  const { result } = renderHook(() => {
    useV1()
  });
  act(() => {
    // how to simulate fast-refresh reload?
    fastRefresh(() => {
      useV2();
    });
  })
  expect(result.current.value).toBeDefined();
});
