React-native/Enzyme：在自然元素上抛出“未知道具”

Question

我正在使用Jest编写测试& React Native中的酶能够充分测试我的组件行为和内部函数。 浅测试似乎确定，但使用时安装它只是抛出

这里是我的package.json。

     "js", 
     "json", 
     "es6" 
    ], 
    "preset": "jest-react-native" 
    } 
} 

现在我的测试很简单。 global.Promise = require.requireActual（'promise'）;

import 'react-native'; 
import React from 'react'; 
import { mount, shallow } from 'enzyme'; 
import { mountToJson } from 'enzyme-to-json'; 

import { LoginScene } from '../../../../../../src/bundles/application/ui/scene/public/LoginScene'; 
import configureStore from '../../../../../../src/configureStore'; 
import { Provider } from 'react-redux'; 

import { getState, getInstance } from '../../../../../../src/testing/enzymeUtils'; 

test('LoginScene', async() => { 
    const store = await configureStore(); 
    let loginScene; 

    const wrapper = mount(
     <Provider store={store}> 
      <LoginScene/> 
     </Provider> 
    ); 

    expect(mountToJson(wrapper)).toMatchSnapshot(); 

    loginScene = wrapper.find(LoginScene); 
    getInstance(loginScene)._handleFieldChange('username', 'despirithium'); 
    getInstance(loginScene)._handleFieldChange('password', 'azerty'); 

    expect(getState(wrapper.find(LoginScene)).username).toBe('despirithium'); 
    expect(getState(wrapper.find(LoginScene)).password).toBe('azerty'); 
}); 

我会浅呈现此，但因为我需要将我的场景包装到提供程序中，这是不可能的。

您可能需要将提供者包装在一个div中。 “...组件必须返回单个根元素...” - https://facebook.github.io/react/docs/components-and-props.html
