Javascript &引用；测试运行完成一秒钟后，Jest没有退出；天然味精

我试着做一个简单的测试

import 'react-native';
import React from 'react';
import App from '../src/App';
import {render} from '@testing-library/react-native';

// Silence the warning https://github.com/facebook/react-native/issues/11094#issuecomment-263240420
jest.mock('react-native/Libraries/Animated/src/NativeAnimatedHelper');

it('renders correctly', async () => {
  const {findByText, findAllByText} = render(<App />);
  const homeText = await findByText(/home/i);
  expect(homeText).toBeTruthy();
});

在web环境中，我看到可以解决停止某些服务的问题，例如

mongoose.close（）

，但在RN idk中，应该停止什么来解决该消息。你能帮我吗

编辑：此pic显示控制台使用

--detectOpenHandles

标志运行

代码如下

  const itemStyle = {color: 'black', fontSize: 26};

  if (isLoading) {
    return <Text>Cargando...</Text>;
  }

  if (error) {
    return <Text>Error al cargas birras</Text>;
  }

你能试试npm测试--detectOpenHandles吗？如果有任何日志，我可以试试这个标志，但是没有任何额外的日志，日志在那里结束：（必须是

中的某个异步操作。你能共享该文件的代码吗？是的，我的主屏幕中有一个api调用，请给我一点时间用该文件的代码编辑帖子。对此有任何更新吗？我最近遇到了相同的错误。你能尝试
