Help: Test Extension

[lsntdev]

I would like to know how we can test the extension, seems that getPluginForTest wont get the extension, Here are the sample of test I was trying to do:

const expect = require('expect');
import React from 'react';
import ReactDOM from 'react-dom';

import { MyExtension } from '../extension/plugins/Extension';
import { getPluginForTest } from '../../MapStore2/web/client/plugins/__tests__/pluginsTestUtils';
import { createStateMocker } from '../../MapStore2/web/client/reducers/__tests__/reducersTestUtils';
import controlsReducer from '../../MapStore2/web/client/reducers/controls';

const DUMMY_ACTION = { type: "DUMMY_ACTION" };

describe('MyExtension', () => {
    const stateMocker = createStateMocker({ controls: controlsReducer });
    beforeEach((done) => {
        document.body.innerHTML = '<div id="container"></div>';
        setTimeout(done);
    });

    afterEach((done) => {
        ReactDOM.unmountComponentAtNode(document.getElementById("container"));
        document.body.innerHTML = '';
        setTimeout(done);
    });
    it('is open?', () => {
        const {Plugin, containers} = getPluginForTest(MyExtension, stateMocker(DUMMY_ACTION), {BurgerMenuPlugin: {}});
        expect(Object.keys(containers)).toContain('BurgerMenu');
        ReactDOM.render(<Plugin />, document.getElementById("container"));
        console.log(document.getElementById("container").innerHTML);
        expect(true).toBe(true);
    });
});

I got the following:

MyExtension
    ✖ is open?
