不知道为什么我在我的简单Main.test文件中收到此错误.

Main.js的构造函数

export class Main extends Component {
    constructor(props) {
        super(props);

        this.state = {
            location: splitString(props.location.pathname,'/dashboard/')
        }

        if (R.isEmpty(props.view)) {
            isViewServices(this.state.location)
                ? this.props.gotoServicesView()
                : this.props.gotoUsersView()
        }
    }

Main.test的

import React from 'react'
import * as enzyme from 'enzyme'
import toJson from 'enzyme-to-json'
import { Main } from './Main'
import Sidebar from '../../components/Common/sidebar'

const main = enzyme.shallow(
