Question

我正在使用Jest＆amp; amp; React Native中的酶可以完全测试我的组件行为和内部功能。浅测试似乎没问题但是当使用mount时它会抛出

这是我的package.json。

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

现在我的测试非常简单。 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');
});

我会浅显示这个但是因为我需要将我的场景包装到提供者中，所以不可能。

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

React-native / Enzyme：mount在本机元素上抛出“未知道具”
