Jest测试在react-loadable中失败

Question

我们有一个使用react-loadable加载的组件，在组件内部也有使用react-loadable加载的子组件。我在jest中遇到的问题是无法加载子组件，尝试了几个来自互联网的建议。请对此提供帮助，以下是必需的详细信息：

lazyload.js

import Loadable from 'react-loadable';
import Loader from './components/ui/genericComponents/Loader';
export const lazyload = (func, fallback) => {
    return Loadable({
        loader: func,
        loading: fallback || Loader,
    });
};

Component.js

import {lazyload} from '../lazyload'
const childComponent1=lazyload(()=>import('./child/childComponent1'));
const childComponent2=lazyload(()=>import('./child/childComponent2'));
const childComponent3=lazyload(()=>import('./child/childComponent3'));

Component.test.js

import React from 'react';
import {configure,mount} from 'enzyme';
import {Component} from '../src/Component';
import axios from 'axios';
import MockAdapter from 'axios-mock-adapter';
configure({ adapter: new Adapter() });

let Wrapper;
beforeAll(() => {
    Wrapper= Enzyme.mount(<Component{...someprops} />);
});

describe('TestSuite for Component',()=>{
//some axios calls
console.log(wrapper.debug()) //I could see the entire wrapper
it('childComponent1',()=>{
console.log(wrapper.debug()) //I only see the loader and not the child Components
})
it('childComponent2',()=>{
console.log(wrapper.debug()) //I only see the loader and not the child Components
})
})

这里的第一个答案与您的问题类似：How test a React Loadable component

这为我解决了这个问题！

简而言之，可以这样做：

// Import your components
    
import Loadable from 'react-loadable';
    
Loadable.preloadAll()
    
describe('TestName', () => {
    //tests
});
