玩笑做出反應原住民如何測試index.PLATFORM.js

Question

怎麼可以這樣進行測試，以獲得開玩笑覆蓋率100％

// @flow 
import { AppRegistry } from 'react-native' 
import App from './src/App' 


AppRegistry.registerComponent('app',() => App) 

是這種是「index.ios.js」和「索引文件.android.js'

新的React Native安裝附帶的默認測試應該按照您的需要進行。

import 'react-native'; 
import React from 'react'; 
import Index from './index.PLATFORM.js'; 

// Note: test renderer must be required after react-native. 
import renderer from 'react-test-renderer'; 

it('renders correctly',() => { 
    const tree = renderer.create(
    <Index /> 
); 
});
