reactjs – JestJS – > Invariant Violation：无法在“Conne

Invariant Violation: Could not find “store” in either the context or props of “Connect(Portfolio)”. Either wrap the root component in a,or explicitly pass “store” as a prop to “Connect(Portfolio)”.

我不确定为什么我在我的Jest测试中收到此错误,因为我的应用程序正在运行,我可以通过调度操作更改我的状态.

index.js

import React from 'react'
import ReactDOM from 'react-dom'
import { createStore,applyMiddleware,compose } from 'redux'
import { Provider } from 'react-redux'
import thunk from 'redux-thunk'
import reducer from './reducer'
import App from './App'

const element = document.getElementById('coinhover');

const store = createStore(reducer,compose(
    applyMiddleware(thunk),window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()
));

ReactDOM.render(
    <Provider store={ store }>
        <App />
    </Provider>,element);

组合组件

import React from 'react'
import { connect } from 'react-redux'

import local_coins from '../../coins.json'
import * as api from '../../services/api'

const mapStateToProps = ({ portfolio }) => ({
    portfolio
});

let localCoins = local_coins;

class Portfolio extends React.Component {
    constructor(props) {
        super(props)
        this.state = {
            loading: true,assets: props.portfolio,total: 0
        };
    }

    componentDidMount() {
        this.setState({ loading: false });
    }

    render() {
        const assets = this.state.assets;
        const total  = this.state.total;

        return (
